$

Market Linked Securities – Leveraged Upside Participation and Contingent Downside, Principal at Risk Securities

Linked to the EURO STOXX 50^® Index

Due December 4, 2019

Following the determination of the Starting Level, the amount you will be paid on your Securities at maturity will not be affected by the closing level of the Reference Asset on any day other than the Calculation Day. If the Ending Level is less than the Starting Level and the percentage decrease is more than 20.00%, you will lose more than 20.00%, and possibly all, of your initial investment in the Securities. In addition, the Securities will not bear interest, and no other payments on your Securities will be made prior to maturity.

The difference between the estimated value of your Securities and the Original Offering Price reflects costs that the Bank expects to incur and profits that the Bank expects to realize in connection with hedging activities related to the Securities. These costs and profits will likely reduce the secondary market price, if any, at which the Underwriters are willing to purchase the Securities. The Underwriters may, but are not obligated to, purchase any Securities. As a result, you may experience an immediate and substantial decline in the market value of your Securities on the Trade Date and you may lose a substantial portion of your initial investment. The Bank's profit in relation to the Securities will vary based on the difference between (i) the amounts received by the Bank in connection with the issuance and the reinvestment return received by the Bank in connection with such amounts and (ii) the costs incurred by the Bank in connection with the issuance of the Securities and the hedging transactions it effects. The Bank's affiliates or the Underwriters’ affiliates may also realize a profit from a hedging transaction with our affiliate and/or an affiliate of Wells Fargo Securities, LLC ("WFS") in connection with your Securities as described under “The Bank’s Estimated Value of the Securities”.

The return on your Securities will relate to the price return of the Reference Asset and will not include a total return or dividend component. The Securities are derivative products based on the performance of the Reference Asset. The Securities do not constitute a direct investment in any of the shares, units or other securities represented by the Reference Asset. By acquiring Securities, you will not have any direct economic or other interest in, claim or entitlement to, or any legal or beneficial ownership of any such share, unit or security and will not have any rights as a shareholder, unitholder or other security holder of any of the issuers including, without limitation, any voting rights or rights to receive dividends or other distributions. 

Scotia Capital (USA) Inc., our affiliate, will purchase the Securities from us for distribution to other registered broker dealers including WFS or will offer the Securities directly to investors. Scotia Capital (USA) Inc. or any of its affiliates or agents may use this pricing supplement in market-making transactions in Securities after their initial sale.  If you are buying Securities from Scotia Capital (USA) Inc. or another of its affiliates or agents, the final pricing supplement to which this pricing supplement relates may be used in a market-making transaction.  See "Supplemental Plan of Distribution (Conflicts of Interest)" in this pricing supplement and on page PS-32 of the accompanying product prospectus supplement.

Investor Suitability

The Securities may be suitable for you if:

The investor suitability considerations identified above are not exhaustive. Whether or not the Securities are a suitable investment for you will depend on your individual circumstances and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the suitability of an investment in the Securities in light of your particular circumstances. You should also review ''Additional Risks'' beginning on page P-11 of this pricing supplement and the ''Additional Risk Factors Specific to the Notes'' beginning on page PS-6 of the accompanying product prospectus supplement for risks related to an investment in the Securities.

Hypothetical Payments AT MATURITY On the Securities

The examples set out below are included for illustration purposes only. The hypothetical Percentage Changes of the Reference Asset used to illustrate the calculation of the Redemption Amount at Maturity (rounded to two decimal places) are not estimates or forecasts of the Starting Level, the Ending Level or the level of the Reference Asset on the Calculation Day or on any Trading Day prior to the Maturity Date. All examples assume that a holder purchased Securities with an aggregate Principal Amount of $1,000.00, the Threshold Level of 80.00% of the Starting Level, a Participation Rate of 160.00%, the midpoint of the specified range for the Participation Rate, and that no market disruption event occurs on the Calculation Day. Amounts below may have been rounded for ease of analysis.

Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of the Bank. If the Bank were to default on its payment obligations, you may not receive any amounts owed to you under the Securities and you could lose your entire investment.

P-8

The following graph represents hypothetical returns only and is not indicative of actual results. The graph demonstrates the hypothetical return on the Securities at maturity for the set of Percentage Changes of the Reference Asset from -100.00% to 100.00% using the same assumptions as set forth above. Your investment may result in a loss of more than 20.00%, and possibly all, of your initial investment in the Securities at maturity.

P-9

Hypothetical Returns on the Securities

Each Security has a Principal Amount of $1,000.

(1) The annualized rates of return are calculated on a semi-annual bond equivalent basis with compounding.

(2) The hypothetical Starting Level (the closing level of the Index on April 26, 2018).

The above figures are for purposes of illustration only and may have been rounded for ease of analysis. The actual amount you receive on the Maturity Date and the resulting pre-tax rates of return will depend on the actual Ending Level and Participation Rate.

In addition to the following risks included in this pricing supplement, we urge you to read "Additional Risk Factors Specific to the Notes" beginning on page PS-5 of the accompanying product prospectus supplement and "Risk Factors" beginning on page S-2 of the accompanying prospectus supplement and page 6 of the accompanying prospectus.

You should understand the risks of investing in the Securities and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Securities in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying prospectus, prospectus supplement and product prospectus supplement.

The Bank's Estimated Value Does Not Represent Future Values of the Securities and may Differ from Others' Estimates

The Bank's estimated value of the Securities is determined by reference to the Bank's internal pricing models when the terms of the Securities are set. This estimated value is based on market conditions and other relevant factors existing at that time and the Bank's assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors as well as an estimate of the difference between the amounts we or our hedge provider pay and receive in a hedging transaction with our affiliate and/or an affiliate of WFS in connection with your Securities. Different pricing models and assumptions could provide valuations for Securities that are greater than or less than the Bank's estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the value of the Securities could change significantly based on, among other things, changes in market conditions, our creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which the Bank would be willing to buy Securities from you in secondary market transactions. See "The Bank's Estimated Value of the Securities" in this pricing supplement.

The Bank's Estimated Value is not Determined by Reference to Credit Spreads for our Conventional Fixed-Rate Debt

The internal funding rate used in the determination of the Bank's estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. If the Bank were to use the interest rate implied by our conventional fixed-rate credit spreads, we would expect the economic terms of the Securities to be more favorable to you. Consequently, our use of an internal funding rate would have an adverse effect on the terms of the Securities and any secondary market prices of the Securities. See "The Bank's Estimated Value of the Securities" in this pricing supplement.

The Securities Differ from Conventional Debt Instruments

The Securities are not conventional notes or debt instruments. The Securities will not provide you with interest payments prior to maturity as a conventional fixed-rate or floating-rate debt security with the same maturity would. The return that you will receive on the Securities, which could be negative, may be less than the return you could earn on other investments.  Even if your return is positive, your return may be less than the return you would earn if you bought a conventional senior interest bearing debt security of the Bank.

No Interest

The Securities will not bear interest and, accordingly, you will not receive any interest payments on the Securities.

Your Investment is Subject to the Credit Risk of The Bank of Nova Scotia

The Securities are senior unsecured debt obligations of the Bank, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus, prospectus supplement and product prospectus supplement, the Securities will rank on a parity with all of the other unsecured and unsubordinated debt obligations of the Bank, except such obligations as may be preferred by operation of law. Any payment to be made on the Securities, including the Redemption Amount at Maturity, depends on the ability of the Bank to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of the Bank may affect the market value of the Securities and, in the event the Bank were to default on its obligations, you may not receive the amounts owed to you under the terms of the Securities. If you sell the Securities prior to maturity, you may receive substantially less than the Principal Amount of your Securities.

The Securities are Subject to Market Risk

The return on the Securities is directly linked to the performance of the Reference Asset and indirectly linked to the value of the Reference Asset Constituent Stocks and the extent to which the Percentage Change is positive or negative. The level of the Reference Asset can rise or fall sharply due to factors specific to the Reference Asset Constituent Stocks, as well as general market factors, such as general market volatility and levels, interest rates and economic and political conditions.

An Investment in the Securities Is Subject to Risks Associated with Non-U.S. Securities

The Reference Asset Constituent Stocks are listed on non-U.S. stock exchanges. Non-U.S. stock exchanges may impose trading limitations intended to prevent extreme fluctuations in individual security prices and may suspend trading in certain circumstances. These actions could limit variations in the closing level of the Reference Asset which could, in turn, adversely affect the value of the Securities and any amounts payable.

P-12

---

Investments in securities linked to the value of non-U.S. equity securities involve particular risks. The non-U.S. securities markets whose stocks comprise the Reference Asset may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect non-U.S. markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize the non-U.S. securities markets, as well as cross-shareholdings in non-U.S. companies, may affect trading prices and volumes in those markets. Also, there is generally less publicly available information about non-U.S. companies than about those U.S. companies that are subject to the reporting requirements of the U.S. Securities and Exchange Commission, and non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies.

Securities prices in non-U.S. countries are subject to political, economic, financial and social factors that apply in those geographical regions. These factors, which could negatively affect those securities markets, include the possibility of recent or future changes in a non-U.S. government’s economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to non-U.S. companies or investments in non-U.S. equity securities and the possibility of fluctuations in the rate of exchange between currencies, the possibility of outbreaks of hostility and political instability and the possibility of natural disaster or adverse public health development in the region. Moreover, non-U.S. economies may differ favorably or unfavorably from the U.S. economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

An Investment in the Securities Is Subject to Risks Associated with the Eurozone and Exchange Rate Risk

The U.K.’s referendum to leave the European Union may adversely affect the performance of the Reference Asset

The Reference Asset Constituent Stock issuers are Eurozone member companies. The U.K.'s referendum on June 23, 2016 to leave the European Union, which we refer to as "Brexit," has and may continue to cause disruptions to capital and currency markets worldwide and to the market tracked by the Reference Asset in particular. The full impact of the Brexit decision, however, remains uncertain. A process of negotiation, which is likely to take a number of years, will determine the future terms of the U.K.'s relationship with the European Union. The performance of the Reference Asset may be negatively affected by interest rate, exchange rate and other market and economic volatility, as well as regulatory and political uncertainty.

The Participation Rate Applies Only at Maturity

You should be willing to hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, the price you receive will likely not reflect the full economic value of the Participation Rate or the Securities themselves, and the return you realize may be less than the then-current Percentage Change even if such return is positive. You will receive the full benefit of the Participation Rate, if applicable, only if you hold your Securities to maturity.

The Redemption Amount at Maturity Is Not Linked to the Level of the Reference Asset at Any Time Other Than the Calculation Day

The Redemption Amount at Maturity will be based on the Ending Level (subject to adjustments as described herein).  Therefore, for example, if the closing level of the Reference Asset declined substantially as of the Calculation Day compared to the Pricing Date, the Redemption Amount at Maturity may be significantly less than it would otherwise have been had the Redemption Amount at Maturity been linked to the closing level of the Reference Asset prior to the Calculation Day.  Although the actual level of the Reference Asset at maturity or at other times during the term of the Securities may be higher than the Ending Level, you will not benefit from the closing level of the Reference Asset at any time other than the Calculation Day.

P-13

If the Levels of the Reference Asset or the Reference Asset Constituent Stocks Change, the Market Value of Your Securities May Not Change in the Same Manner

Your Securities may trade quite differently from the performance of the Reference Asset or the Reference Asset Constituent Stocks. Changes in the levels of the Reference Asset or the Reference Asset Constituent Stocks may not result in a comparable change in the market value of your Securities. We discuss some of the reasons for this disparity under "—The Price at Which the Securities may be Sold prior to Maturity will Depend on a Number of Factors and May Be Substantially Less Than the Amount for Which They Were Originally Purchased" below.

Holding the Securities is Not the Same as Holding the Reference Asset Constituent Stocks

Holding the Securities is not the same as holding the Reference Asset Constituent Stocks. As a holder of the Securities, you will not be entitled to the voting rights or rights to receive dividends or other distributions or other rights that holders of the Reference Asset Constituent Stocks would enjoy.

No Assurance that the Investment View Implicit in the Securities Will Be Successful

Furthermore, we cannot give you any assurance that the future performance of the Reference Asset or the Reference Asset Constituent Stocks will result in your receiving an amount greater than or equal to the Principal Amount of your Securities.  Certain periods of historical performance of the Reference Asset or the Reference Asset Constituent Stocks would have resulted in you receiving less than the Principal Amount of your Securities if you had owned securities with terms similar to these Securities in the past.   See "Information Regarding the Reference Asset" in this pricing supplement for further information regarding the historical performance of the Reference Asset.

The Reference Asset Reflects Price Return Only and Not Total Return

The return on your Securities is based on the performance of the Reference Asset, which reflects the changes in the market prices of the Reference Asset Constituent Stocks. It is not, however, linked to a ''total return'' index or strategy, which, in addition to reflecting those price returns, would also reflect dividends paid on the Reference Asset Constituent Stocks. The return on your Securities will not include such a total return feature or dividend component.

Past Performance is Not Indicative of Future Performance

The actual performance of the Reference Asset over the life of the Securities, as well as the amount payable at maturity, may bear little relation to the historical performance of the Reference Asset or to the hypothetical return examples set forth elsewhere in this pricing supplement. We cannot predict the future performance of the Reference Asset.

We May Sell an Additional Aggregate Principal Amount of the Securities at a Different Issue Price

We may decide to sell an additional aggregate Principal Amount of the Securities subsequent to the date of the final pricing supplement. The issue price of the Securities in the subsequent sale may differ substantially (higher or lower) from the Original Offering Price provided on the cover of this pricing supplement.

Changes Affecting the Reference Asset Could Have an Adverse Effect on the Value of the Securities

The policies of STOXX Limited, the index sponsor (the “Sponsor”) concerning additions, deletions and substitutions of the Reference Asset Constituent Stocks and the manner in which the Sponsor takes account of certain changes affecting those Reference Asset Constituent Stocks may adversely affect the level of the Reference Asset. The policies of the Sponsor with respect to the calculation of the Reference Asset could also adversely affect the level of the Reference Asset. The Sponsor may discontinue or suspend calculation or dissemination of the Reference Asset. Any such actions could have a material adverse effect on the value of, and any amounts payable on, the Securities.

P-14

---

The Bank Cannot Control Actions by the Sponsor and the Sponsor Has No Obligation to Consider Your Interests

The Bank and its affiliates are not affiliated with the Sponsor and have no ability to control or predict its actions, including any errors in or discontinuation of public disclosure regarding methods or policies relating to the calculation of the Reference Asset. The Sponsor is not involved in the Securities offering in any way and has no obligation to consider your interest as an owner of the Securities in taking any actions that might negatively affect the market value of your Securities.

The Price at Which the Securities May Be Sold Prior to Maturity will Depend on a Number of Factors and May Be Substantially Less Than the Amount for Which They Were Originally Purchased

Depending on the actual or anticipated level of the Reference Asset and other relevant factors, the market value of the Securities may decrease and you may receive substantially less than 100.00% of the Original Offering Price if you sell your Securities prior to maturity.

The Securities Lack Liquidity

The Securities will not be listed on any securities exchange or automated quotation system. Therefore, there may be little or no secondary market for the Securities. Scotia Capital (USA) Inc. may, but is not obligated to, make a market in the Securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Securities easily. Because we do not expect that other broker-dealers will participate significantly in the secondary market for the Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which Scotia Capital (USA) Inc. is willing to purchase the Securities from you. If at any time Scotia Capital (USA) Inc. was not to make a market in the Securities, it is likely that there would be no secondary market for the Securities. Accordingly, you should be willing to hold your Securities to maturity. 

Hedging Activities by the Bank and/or the Underwriters May Negatively Impact Investors in the Securities and Cause Our Respective Interests and Those of Our Clients and Counterparties to Be Contrary to Those of Investors in the Securities

The Bank or one or more of our respective affiliates and/or the Underwriters has hedged or expects to hedge the obligations under the Securities by purchasing futures and/or other instruments linked to the Reference Asset. The Bank or one or more of our respective affiliates and/or the Underwriters also expects to adjust the hedge by, among other things, purchasing or selling any of the foregoing, and perhaps other instruments linked to the Reference Asset or one or more of the Reference Asset Constituent Stocks, at any time and from time to time, and to unwind the hedge by selling any of the foregoing on or before the Calculation Day.

The Bank or one or more of our respective affiliates and/or the Underwriters may also enter into, adjust and unwind hedging transactions relating to other basket- or index-linked securities whose returns are linked to changes in the level or price of the Reference Asset or the Reference Asset Constituent Stocks. Any of these hedging activities may adversely affect the level of the Reference Asset—directly or indirectly by affecting the price of the Reference Asset Constituent Stocks—and therefore the market value of the Securities and the amount you will receive, if any, on the Securities. In addition, you should expect that these transactions will cause the Bank, our respective affiliates and/or the Underwriters, or our respective clients or counterparties, to have economic interests and incentives that do not align with, and that may be directly contrary to, those of an investor in the Securities. The Bank, our respective affiliates and/or the Underwriters will have no obligation to take, refrain from taking or cease taking any action with respect to these transactions based on the potential effect on an investor in the Securities, and may receive substantial returns with respect to these hedging activities while the value of the Securities may decline.

P-15

---

Market Activities by the Bank or the Underwriters for Their Own Respective Accounts or for Their Respective Clients Could Negatively Impact Investors in the Securities

The Bank, the Underwriters and their respective affiliates provide a wide range of financial services to a substantial and diversified client base. As such, each of the Bank, the Underwriters and their respective affiliates may act as an investor, investment banker, research provider, investment manager, investment advisor, market maker, trader, prime broker or lender. In those and other capacities, we and/or our affiliates and the Underwriters and/or their respective affiliates purchase, sell or hold a broad array of investments, actively trade securities (including the Securities or other securities that we have issued), the Reference Asset Constituent Stocks, derivatives, loans, credit default swaps, indices, baskets and other financial instruments and products for our own accounts or for the accounts of our customers, and we and the Underwriters will have other direct or indirect interests in those securities and in other markets that may not be consistent with your interests and may adversely affect the level of the Reference Asset and/or the value of the Securities. Any of these financial market activities may, individually or in the aggregate, have an adverse effect on the level of the Reference Asset and the market for your Securities, and you should expect that our interests and those of our affiliates and those of the Underwriters and/or of their respective affiliates, or our or their clients or counterparties, will at times be adverse to those of investors in the Securities.

The Bank, the Underwriters and their respective affiliates regularly offer a wide array of securities, financial instruments and other products into the marketplace, including existing or new products that are similar to the Securities or other securities that we may issue, the Reference Asset Constituent Stocks or other securities or instruments similar to or linked to the foregoing. Investors in the Securities should expect that the Bank, the Underwriters and their respective affiliates will offer securities, financial instruments, and other products that may compete with the Securities for liquidity or otherwise.

In addition, our and their affiliates or any dealer participating in the offering of the Securities or its affiliates may, at present or in the future, publish research reports on the Reference Asset or the Reference Asset Constituent Stocks. This research is modified from time to time without notice and may, at present or in the future, express opinions or provide recommendations that are inconsistent with purchasing or holding the Securities. Any research reports on the Reference Asset or the Reference Asset Constituent Stocks could adversely affect the level of the Reference Asset and, therefore, adversely affect the value of and your return on the Securities. You are encouraged to derive information concerning the Reference Asset from multiple sources and should not rely on the views expressed by us, the Underwriters or our or their affiliates or any participating dealer or its affiliates.

The Bank, the Underwriters and Their Respective Affiliates Regularly Provide Services to, or Otherwise Have Business Relationships with, a Broad Client Base, Which Has Included and May Include the Issuers of the Reference Asset Constituent Stocks

The Bank, the Underwriters and their respective affiliates regularly provide financial advisory, investment advisory and transactional services to a substantial and diversified client base. You should assume that the Bank or the Underwriters will, at present or in the future, provide such services or otherwise engage in transactions with, among others, the issuers of the Reference Asset Constituent Stocks, or transact in securities or instruments or with parties that are directly or indirectly related to these entities. These services could include making loans to or equity investments in those companies, providing financial advisory or other investment banking services, or issuing research reports. You should expect that the Bank, the Underwriters and their respective affiliates, in providing these services, engaging in such transactions, or acting for their own accounts, may take actions that have direct or indirect effects on the Securities or other securities that the Bank may issue, the Reference Asset Constituent Stocks or other securities or instruments similar to or linked to the foregoing, and that such actions could be adverse to the interests of investors in the Securities. In addition, in connection with these activities, certain personnel within the Bank or the Underwriters and their respective affiliates may have access to confidential material non-public information about these parties that would not be disclosed to investors in the Securities.

Other Investors in the Securities May Not Have the Same Interests as You

The interests of other investors may, in some circumstances, be adverse to your interests. Other investors may make requests or recommendations to us regarding the establishment of transactions on terms that are adverse to your interests, and investors in the Securities are not required to take into account the interests of any other investor in exercising remedies, voting or other rights in their capacity as noteholders. Further, other investors may enter into market transactions with respect to the Securities, assets that are the same or similar to the Securities, assets referenced by the Securities (such as stocks or stock indices) or other similar assets or securities which may adversely impact the market for or value of your Securities. For example, an investor could take a short position (directly or indirectly through derivative transactions) in respect of securities similar to your Securities or in respect of the Reference Asset.

P-16

The Calculation Agent Can Postpone the Calculation Day for the Securities if a Market Disruption Event with Respect to the Reference Asset Occurs

If the Calculation Agent determines, in its sole discretion, that, on a day that would otherwise be the Calculation Day, a market disruption event with respect to the Reference Asset has occurred or is continuing for the Reference Asset, the Calculation Day will be postponed until the first following Trading Day on which no market disruption event occurs or is continuing, although the Calculation Day will not be postponed by more than eight scheduled Trading Days. Moreover, if the Calculation Day is postponed to the last possible day, but a market disruption event occurs or is continuing on that day, that day will nevertheless be the Calculation Day, and the Calculation Agent will determine the applicable Ending Level that must be used to determine the Redemption Amount at Maturity. See "General Terms of the Notes—Unavailability of the Level of the Reference Asset on a Valuation Date" beginning on page PS-19 in the accompanying product prospectus supplement and “Summary—Market Disruption Event” herein.

There Is No Affiliation Between Any Reference Asset Constituent Stock Issuers or the Sponsor and Us and We Are Not Responsible for Any Disclosure by Any of the Other Reference Asset Constituent Stock Issuers or the Sponsor

The Bank, the Underwriters and their respective affiliates may currently, or from time to time in the future, engage in business with the issuers of the Reference Asset Constituent Stocks. Nevertheless, none of us, the Underwriters or our or their affiliates assumes any responsibility for the accuracy or the completeness of any information about the Reference Asset or any of the other Reference Asset Constituent Stocks. Before investing in the Securities you should make your own investigation into the Reference Asset and the issuers of the Reference Asset Constituent Stocks. See the section below entitled "Information Regarding the Reference Asset" in this pricing supplement for additional information about the Reference Asset.

A Participating Dealer or its Affiliates May Realize Hedging Profits Projected by its Proprietary Pricing Models in Addition to any Selling Concession, Creating a Further Incentive for the Participating Dealer to Sell the Securities to You

If any dealer participating in the distribution of the Securities (referred to as a "participating dealer") or any of its affiliates conducts hedging activities for us in connection with the Securities, that participating dealer or its affiliate will expect to realize a projected profit from such hedging activities. If a participating dealer receives a concession for the sale of the Securities to you, this projected profit will be in addition to the concession, creating a further incentive for the participating dealer to sell the Securities to you.

Uncertain Tax Treatment

Significant aspects of the tax treatment of the Securities are uncertain. You should consult your tax advisor about your tax situation. See "Canadian Income Tax Consequences" and "U.S. Federal Income Tax Consequences" in this pricing supplement.

The conclusion that no portion of the interest paid or credited or deemed to be paid or credited on a Security will be “Participating Debt Interest” subject to Canadian withholding tax is based in part on the current published administrative position of the CRA. There cannot be any assurance that CRA’s current published administrative practice will not be subject to change, including potential expansion in the current administrative interpretation of Participating Debt Interest subject to Canadian withholding tax. If, at any time, the interest paid or credited or deemed to be paid or credited on a Security is subject to Canadian withholding tax, you will receive an amount that is less than the Redemption Amount. You should consult your own adviser as to the potential for such withholding and the potential for reduction or refund of part or all of such withholding, including under any bilateral Canadian tax treaty the benefits of which you may be entitled. For a discussion of the Canadian federal income tax consequences of investing in the notes, see “Canadian Income Tax Consequences” below, “Canadian Taxation—Debt Securities” on page 50 of the accompanying prospectus dated February 1, 2017, and “Supplemental Discussion of Canadian Federal Income Tax Consequences” on page PS-24 of the accompanying product prospectus supplement.

INFORMATION REGARDING THE REFERENCE ASSET

EURO STOXX 50^® Index

The following is a summary description of the EURO STOXX 50^® Index (referred to in this section as the “Index”) based on information obtained from the website of the Sponsor, STOXX Limited at stoxx.com. All information regarding the Index contained herein, including its make-up, method of calculation and changes in its components, has been derived from publicly available sources and its accuracy cannot be guaranteed. That information reflects the policies of, and is subject to change by, the Sponsor.

Supplemental Plan of Distribution (Conflicts of Interest)

Pursuant to the terms of a distribution agreement, Scotia Capital (USA) Inc., an affiliate of The Bank of Nova Scotia, will purchase the Securities from The Bank of Nova Scotia for distribution to other registered broker-dealers or will offer the Securities directly to investors.

In addition, Scotia Capital (USA) Inc. or another of its affiliates or agents may use this pricing supplement in market-making transactions after the initial sale of the Securities. While the Underwriters may make markets in the Securities, they are under no obligation to do so and may discontinue any market-making activities at any time without notice. See the sections titled "Supplemental Plan of Distribution" in the accompanying prospectus supplement and product prospectus supplement.

The price at which you purchase the Securities includes costs that the Bank, the Underwriters or their affiliates expect to incur and profits that the Bank, the Underwriters or their affiliates expect to realize in connection with hedging activities related to the Securities, as set forth above. These costs and profits will likely reduce the secondary market price, if any secondary market develops, for the Securities.  As a result, you may experience an immediate and substantial decline in the market value of your Securities on the Original Issue Date.

Conflicts of Interest

Each of Scotia Capital (USA) Inc., and Scotia Capital Inc. is an affiliate of the Bank and, as such, has a ''conflict of interest'' in this offering within the meaning of FINRA Rule 5121. In addition, the Bank will receive the gross proceeds from the initial public offering of the Securities, thus creating an additional conflict of interest within the meaning of Rule 5121. Consequently, the offering is being conducted in compliance with the provisions of Rule 5121. Neither Scotia Capital (USA) Inc. nor Scotia Capital Inc. is permitted to sell Securities in this offering to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.

The Underwriters and their respective affiliates are full service financial institutions engaged in various activities,  which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.  The Underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for the Bank, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the Underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the Bank.  The Underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The Bank's Estimated Value of the Securities

The Bank's estimated value of the Securities set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the Securities, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the Securities. The Bank's estimated value does not represent a minimum price at which the Bank would be willing to buy your Securities in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the Bank's estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the Securities as well as the higher issuance, operational and ongoing liability management costs of the Securities in comparison to those costs for our conventional fixed-rate debt. For additional information, see "Additional Risk Factors—The Bank's Estimated Value Is Not Determined by Reference to Credit Spreads for Our Conventional Fixed-Rate Debt." The value of the derivative or derivatives underlying the economic terms of the Securities is derived from the Bank's internal pricing model. This model is dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, the Bank's estimated value of the Securities is determined when the terms of the Securities are set based on market conditions and other relevant factors and assumptions existing at that time. See "Additional Risk Factors—The Bank's Estimated Value Does Not Represent Future Values of the Securities and May Differ from Others' Estimates."

The Bank's estimated value of the Securities will be lower than the Original Offering Price of the Securities because costs associated with selling, structuring and hedging the Securities are included in the Original Offering Price of the Securities. These costs include the selling commissions paid to the Underwriters and other affiliated or unaffiliated dealers, the projected profits that we or our hedge provider expect to realize for assuming risks inherent in hedging our obligations under the Securities and the estimated cost of hedging our obligations under the Securities. The profits also include an estimate of the difference between the amounts we or our hedge provider pay and receive in a hedging transaction with our affiliate and/or an affiliate of WFS in connection with your Securities. We pay to such hedge provider amounts based on, but at a discount to, what we would pay to holders of a non-structured note with a similar maturity. In return for such payment, such hedge provider pays to us the amount we owe under the Securities. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the Securities. See "Additional Risk Factors—The Bank's Estimated Value of the Securities Will Be Lower Than the Original Offering Price of the Securities" in this pricing supplement.

EVENTS OF DEFAULT AND ACCELERATION

If the Securities have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the Securities, the Calculation Agent will determine the default amount as described below.

Default Amount

The default amount for your Securities on any day (except as provided in the last sentence under "Default Quotation Period" below) will be an amount, in the specified currency for the principal of your Securities, equal to the cost of having a qualified financial institution, of the kind and selected as described below, expressly assume all our payment and other obligations with respect to your Securities as of that day and as if no default or acceleration had occurred, or to undertake other obligations providing substantially equivalent economic value to you with respect to your Securities. That cost will equal:

●     the lowest amount that a qualified financial institution would charge to effect this assumption or undertaking, plus

●   the reasonable expenses, including reasonable attorneys' fees, incurred by the trustees of your Securities in preparing any documentation necessary for this assumption or undertaking.

Default Quotation Period

The default quotation period is the period beginning on the day the default amount first becomes due (the "due date") and ending on the third Business Day after that day, unless:

·      no quotation of the kind referred to above is obtained, or

·      every quotation of that kind obtained is objected to within five Business Days after the due date as described above.

If either of these two events occurs, the default quotation period will continue until the third Business Day after the first Business Day on which prompt notice of an objection is given as described above. If that quotation is objected to as described above within five Business Days after that first Business Day, however, the default quotation period will continue as described in the prior sentence and this sentence.

Qualified Financial Institutions

For the purpose of determining the default amount at any time, a qualified financial institution must be a financial institution organized under the laws of any jurisdiction in the United States of America, Europe or Japan, which at that time has outstanding debt obligations with a stated maturity of one year or less from the date of issue and that is, or whose notes are, rated either:

·     A-1 or higher by Standard & Poor's Ratings Services, or any successor, or any other comparable rating then used by that rating agency, or

·     P-1 or higher by Moody's Investors Service or any successor, or any other comparable rating then used by that rating agency.

If the Securities have become immediately due and payable following an event of default, you will not be entitled to any additional payments with respect to the Securities. For more information, see "Description of the Debt Securities We May Offer—Events of Default" beginning on page 27 of the accompanying prospectus.

Tax Redemption

The Bank (or its successor) may redeem the Securities, in whole but not in part, at a redemption price determined by the Calculation Agent in a manner reasonably calculated to preserve your and our relative economic position, upon the giving of a notice as described below, if:

• as a result of any change (including any announced prospective change) in or amendment to the laws (or any regulations or rulings promulgated thereunder) of Canada (or the jurisdiction of organization of the successor to the Bank) or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in official position regarding the application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after the Pricing Date (or, in the case of a successor to the Bank, after the date of succession), and which in the written opinion to the Bank (or its successor) of legal counsel of recognized standing has resulted or will result (assuming, in the case of any announced prospective change, that such announced change will become effective as of the date specified in such announcement and in the form announced) in the Bank (or its successor) becoming obligated to pay, on the next succeeding date on which a payment is due, additional amounts with respect to the Securities; or
• on or after the Pricing Date (or, in the case of a successor to the Bank, after the date of succession), any action has been taken by any taxing authority of, or any decision has been rendered by a court of competent jurisdiction in, Canada (or the jurisdiction of organization of the successor to the Bank) or any political subdivision or taxing authority thereof or therein, including any of those actions specified in the paragraph immediately above, whether or not such action was taken or decision was rendered with respect to the Bank (or its successor), or any change, amendment, application or interpretation shall be officially proposed, which, in any such case, in the written opinion to the Bank (or its successor) of legal counsel of recognized standing, will result (assuming, that such change, amendment or action is applied to the Securities by the taxing authority and that, in the case of any announced prospective change, that such announced change will become effective as of the date specified in such announcement and in the form announced) in the Bank (or its successor) becoming obligated to pay, on the next succeeding date on which a payment is due, additional amounts with respect to the Securities;

and, in any such case, the Bank (or its successor), in its business judgment, determines that such obligation cannot be avoided by the use of reasonable measures available to it (or its successor).

In the event the Bank elects to redeem the Securities, the Calculation Agent shall determine the redemption price in its discretion and deliver to the trustees a certificate, signed by an authorized officer, stating that the Bank is entitled to redeem such Securities pursuant to their terms in whole only.

The Bank will give notice of intention to redeem such Securities to holders of the Securities not more than 45 nor less than 30 days prior to the date fixed for redemption specifying, among other things, the date fixed for redemption, and on or promptly after the redemption date, it will give notice of the redemption price.

Other than as described above, the Securities are not redeemable prior to their maturity.

Canadian Income Tax Consequences

An investor should read carefully the description of principal Canadian federal income tax considerations under “Canadian Taxation” in the accompanying prospectus relevant to a holder (as defined on page 19 of the accompanying prospectus) owning debt securities, and the description of principal Canadian federal income tax considerations under “Supplemental Discussion of Canadian Federal Income Tax Consequences” in the accompanying product prospectus supplement.”

U.S. FEDERAL INCOME TAX CONSEQUENCES

U.S. Tax Treatment. Pursuant to the terms of the Securities, the Bank and you agree, in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary, to characterize your Securities as pre-paid derivative contracts with respect to the Reference Asset. If your Securities are so treated, you should generally recognize gain or loss upon the taxable disposition of your Securities in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Securities. Such recognized gain or loss should generally be long-term capital gain or loss if you have held your Securities for more than one year (otherwise such gain or loss should be short-term capital gain or loss if you have held your Securities for one year or less).The deductibility of capital losses is subject to limitations.

In the opinion of our counsel, Cadwalader, Wickersham & Taft LLP, it would be reasonable to treat your Securities in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the Securities, it is possible that your Securities could alternatively be treated for tax purposes as a single contingent payment debt instrument, or pursuant to some other characterization, such that the timing and character of your income from the Securities could differ materially and adversely from the treatment described above.

spouse), $125,000 for a married individual filing a separate return, or the dollar amount at which the highest tax bracket begins for an estate or trust. The 3.8% tax is determined in a different manner than the income tax. U.S. holders should consult their tax advisors as to the consequences of the 3.8% tax with respect to their investments in the Securities.

Specified Foreign Financial Assets. U.S. holders may be subject to reporting obligations with respect to their Securities if they do not hold their Securities in an account maintained by a financial institution and the aggregate value of their Securities and certain other “specified foreign financial assets” (applying certain attribution rules) exceeds an applicable threshold. Significant penalties can apply if a U.S. holder is required to disclose its Securities and fails to do so.

Non-U.S. Holders. This section applies only if you are a non-U.S. holder. For these purposes, you are a non-U.S. holder if you are the beneficial owner of the Securities and are, for U.S. federal income tax purposes:

• a non-resident alien individual;
• a foreign corporation; or
• an estate or trust that, in either case, is not subject to U.S. federal income tax on a net income basis on income or gain from the Securities.

FATCA. The Foreign Account Tax Compliance Act (“FATCA”) was enacted on March 18, 2010, and imposes a 30% U.S. withholding tax on “withholdable payments” (i.e., certain U.S.-source payments, including interest (and original issue discount), dividends, other fixed or determinable annual or periodical gain, profits, and income, and on the gross proceeds from a disposition of property of a type which can produce U.S.-source interest or dividends) and “passthru payments” (i.e., certain payments attributable to withholdable payments) made to certain foreign financial institutions (and certain of their affiliates) unless the payee foreign financial institution agrees (or is required), among other things, to disclose the identity of any U.S. individual with an account at the institution (or the relevant affiliate) and to annually report certain information about such account. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or do not certify that they do not have any substantial U.S. owners) to withhold tax at a rate of 30%. Under certain circumstances, a holder may be eligible for refunds or credits of such taxes.

Pursuant to final and temporary Treasury regulations and other IRS guidance, the withholding and reporting requirements under FATCA will generally apply to certain “withholdable payments” made on or after July 1, 2014, certain gross proceeds on a sale or disposition occurring after December 31, 2018, and certain foreign passthru payments made after December 31, 2018 (or, if later, the date that final regulations defining the term “foreign passthru payment” are published). If withholding is required, we (or the applicable paying agent) will not be required to pay additional amounts with respect to the amounts so withheld. Foreign financial institutions and non-financial foreign entities located in jurisdictions that have an intergovernmental agreement with the U.S. governing FATCA may be subject to different rules.

Investors should consult their own advisors about the application of FATCA, in particular if they may be classified as financial institutions (or if they hold their Securities through a non-U.S. entity) under the FATCA rules.

Both U.S. and non-U.S. holders should consult their tax advisors regarding the U.S. federal income tax consequences of an investment in the Securities, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction (including that of the Bank and of issuers of the Reference Asset Constituent Stocks).
