The notes are being issued by The Bank of Nova Scotia (“BNS”). There are important differences between the notes and a conventional debt security, including different investment risks and certain additional costs. See “Risk Factors” beginning on page TS-6 of this term sheet and beginning on page PS-6 of product prospectus supplement EQUITY INDICES LIRN-1.

The initial estimated value of the notes as of the pricing date is expected to be between $9.15 and $9.61 per unit, which is less than the public offering price listed below. See “Summary” on the following page, “Risk Factors” beginning on page TS-6 of this term sheet and “Structuring the Notes” on page TS-11 of this term sheet for additional information. The actual value of your notes at any time will reflect many factors and cannot be predicted with accuracy.

October     , 2017

The Leveraged Index Return Notes^® Linked to the Dow Jones Industrial Average^SM, due October  , 2022 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the CDIC or the FDIC, and are not, either directly or indirectly, an obligation of any third party. The notes will rank equally with all of our other unsecured senior debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of BNS. The notes provide you a leveraged return if the Ending Value of the Market Measure, which is the Dow Jones Industrial Average^SM (the “Index”), is greater than the Starting Value.  If the Ending Value is equal to or less than the Starting Value but greater than or equal to the Threshold Value, you will receive the principal amount of your notes.  If the Ending Value is less than the Threshold Value, you will lose a portion, which could be significant, of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Participation Rate) are based on our internal funding rate, which is the rate we would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements.  Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging related charge described below, will reduce the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes will be greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This range of estimated values was determined by reference to our internal pricing models, which take into consideration certain factors, such as our internal funding rate on the pricing date and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-11.

All disclosures contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation, and changes in its components, have been derived from publicly available sources. The information reflects the policies of, and is subject to change by, S&P Dow Jones Indices LLC (the “Index sponsor”). The Index sponsor, which licenses the copyright and all other rights to the Index, has no obligation to continue to publish, and may discontinue publication of, the Index. The consequences of the Index sponsor discontinuing publication of the Index are discussed in the section entitled “Description of LIRNs—Discontinuance of an Index” beginning on page PS-20 of product prospectus supplement EQUITY INDICES LIRN-1.  None of us, the calculation agent, or MLPF&S accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

Publication of the Index

Unless otherwise stated, all information on the Index provided in this term sheet is derived from S&P Dow Jones Indices LLC. The Index is a price-weighted index, which means an underlying stock’s weight in the Index is based on its price per share rather than the total market capitalization of the issuer. The Index is designed to provide an indication of the composite performance of 30 common stocks of corporations representing a broad cross-section of U.S. industry. The corporations represented in the Index tend to be market leaders in their respective industries and their stocks are typically widely held by individuals and institutional investors.

The Index is maintained by an Averages Committee comprised of three representatives of S&P Dow Jones Indices LLC and two representatives of The Wall Street Journal (“WSJ”). While there are no rules for component selection, a stock typically is added only if it has an excellent reputation, demonstrates sustained growth and is of interest to a large number of investors.

Unlike most other indices, which are reconstituted according to a fixed review schedule, constituents of the Index are reviewed on an as-needed basis. Changes to the common stocks included in the Index tend to be made infrequently, and the underlying stocks of the Index may be changed at any time.

The Index initially consisted of 12 common stocks and was first published in the WSJ in 1896. The Index was increased to include 20 common stocks in 1916 and to 30 common stocks in 1928. The number of common stocks in the Index has remained at 30 since 1928, and, in an effort to maintain continuity, the constituent corporations represented in the Index have been changed on a relatively infrequent basis. Nine main groups of companies constitute the Index, with the approximate sector weights of the Index as of August 31, 2017 indicated in parentheses: Technology (31.5%); Health Care (15.5%); Financials (11.6%); Industrials (10.5%); Consumer Services (9.6%); Oil & Gas (8.8%); Consumer Goods (8.0%); Telecommunications (3.3%); and Basic Materials (1.2%).

Computation of the Index

The level of the Index is the sum of the primary exchange prices of each of the 30 component stocks included in the Index, divided by a divisor that is designed to provide a meaningful continuity in the level of the Index. Because the Index is price-weighted, stock splits or changes in the component stocks could result in distortions in the Index level. In order to prevent these distortions related to extrinsic factors, the divisor is periodically changed in accordance with a mathematical formula that reflects adjusted proportions within the Index. The current divisor of the Index is published daily in the WSJ and other publications. In addition, other statistics based on the Index may be found in a variety of publicly available sources.

The following graph shows the daily historical performance of the Index in the period from January 1, 2008 through September 21, 2017.  We obtained this historical data from Bloomberg L.P.  We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On September 21, 2017, the closing level of the Index was 22,359.23.

 

Historical Performance of the Index

This historical data on the Index is not necessarily indicative of the future performance of the Index or what the value of the notes may be. Any historical upward or downward trend in the level of the Index during any period set forth above is not an indication that the level of the Index is more or less likely to increase or decrease at any time over the term of the notes.

Before investing in the notes, you should consult publicly available sources for the levels of the Index.

Summary of Canadian Federal 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 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 applicable product prospectus supplement.

Summary of U.S. Federal Income Tax Consequences

The following is a general description of certain U.S. federal tax considerations relating to the notes. Prospective purchasers of the notes should consult their tax advisors as to the consequences under the tax laws of the country of which they are residents for tax purposes and the tax laws of the U.S. of acquiring, holding and disposing of the notes and receiving payments under the notes. This summary is based upon the law as in effect on the date of this pricing supplement and is subject to any change in law that may take effect after such date. We urge you to read the more detailed discussion in the “Supplemental Discussion of U.S. Federal Income Tax Consequences” section beginning on page PS-28 of product prospectus supplement EQUITY INDICES LIRN-1.

No statutory, judicial or administrative authority directly discusses how the notes should be treated for U.S. federal income tax purposes. As a result, the U.S. federal income tax consequences of your investment in the notes are uncertain. Accordingly, we urge you to consult your tax advisor as to the tax consequences of your investment in the notes (and of having agreed to the required tax treatment of your notes described below) and as to the application of state, local or other tax laws to your investment in your notes and the possible effects of changes in federal or other tax laws.

Pursuant to the terms of the notes, BNS and you agree, in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary, to characterize your notes as a pre-paid derivative contract with respect to the Index. If your notes are so treated, you should generally recognize long-term capital gain or loss if you hold your notes for more than one year (and otherwise, short-term capital gain or loss) upon the sale, exchange, redemption or maturity of your notes in an amount equal to the difference between the amount you receive at such time and the amount you paid for your notes. 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 notes in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the notes, it is possible that your notes 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 notes could differ materially from the treatment described above.

Possible Change in Law. In 2007, the Internal Revenue Service (the “IRS”) released a notice that may affect the taxation of holders of the notes. According to the notice, the IRS and the U.S. Treasury Department are actively considering whether a holder of an instrument such as the notes should be required to accrue ordinary income on a current basis, and they are seeking taxpayer comments on the subject. It is not possible to determine what guidance they will ultimately issue, if any. It is possible, however, that under such guidance, holders of the notes will ultimately be required to accrue income currently and this could be applied on a retroactive basis. The IRS and the U.S. Treasury Department are also considering other relevant issues, including whether additional

Leveraged Index Return Notes® Linked to the Dow Jones Industrial AverageSM, due October  , 2022

gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, and whether the special “constructive ownership rules” of Section 1260 of the Internal Revenue Code of 1986, as amended (the “Code”) should be applied to such instruments.

Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is furnished to the IRS.

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 notes 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 notes.

If you are a non-U.S. holder, subject to Section 871(m) and FATCA discussed below, you should generally not be subject to generally applicable information reporting and backup withholding requirements with respect to payments on your notes if you comply with certain certification and identification requirements as to your foreign status including providing us (and/or the applicable withholding agent) a properly executed and fully completed applicable IRS Form W-8. Subject to Section 897 and Section 871(m), discussed below, gain from the sale, exchange or redemption of the notes or settlement at maturity generally will not be subject to U.S. tax unless such gain is effectively connected with a trade or business conducted by you in the U.S. or unless you are a non-resident alien individual and are present in the U.S. for 183 days or more during the taxable year of such sale, exchange or settlement and certain other conditions are satisfied.

We will not attempt to ascertain whether the issuer of any underlying equity constituent of the Index would be treated as a “United States real property holding corporation” (“USRPHC”) within the meaning of Section 897 of the Code. If an issuer of any underlying equity constituent of the Index or the notes were so treated, certain adverse U.S. federal income tax consequences could possibly apply, including subjecting any gain realized by a non-U.S. holder in respect of the notes upon a sale, exchange, early redemption or other taxable disposition (including cash settlement) of the notes to U.S. federal income tax on a net basis, and the proceeds from such a taxable disposition to a withholding tax. Non-U.S. holders should consult their tax advisors regarding the potential treatment of any underlying equity constituent for their notes as a United States real property holding corporation or the notes as United States real property interests.

Section 871 (m). A 30% withholding tax (which may be reduced by an applicable income tax treaty) is imposed under Section 871(m) of the Code on certain “dividend equivalents” paid or deemed paid to a non-U.S. holder with respect to a “specified equity-linked instrument” that references one or more dividend-paying U.S. equity securities or indices containing U.S. equity securities.  The withholding tax can apply even if the instrument does not provide for payments that reference dividends.  Treasury regulations provide that the withholding tax applies to all dividend equivalents paid or deemed paid on specified equity-linked instruments that have a delta of one (“delta one specified equity-linked instruments”) issued after 2016 and to all dividend equivalents paid or deemed paid on all other specified equity-linked instruments issued after 2018.

Based on our determination that the notes are not “delta-one” with respect to the Index or any U.S. Index components, our counsel is of the opinion that the notes should not be delta-one specified equity-linked instruments and thus should not be subject to withholding on dividend equivalents. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Furthermore, the application of Section 871(m) of the Code will depend on our determinations made upon issuance of the notes. If withholding is required, we will not make payments of any additional amounts.

Nevertheless, after issuance, it is possible that your notes could be deemed to be reissued for tax purposes upon the occurrence of certain events affecting the Index or Index components or your notes, and following such occurrence your notes could be treated as
