Re: North Square Investments Trust Registration Statement on Form N-1A File Nos. 333-226989 and 811-23373

Ladies and Gentlemen:

As counsel to North Square Investments Trust, a Delaware statutory trust (the “Trust”), we have been asked to render our opinion with respect to the issuance of shares of beneficial interest of the Trust (the “Shares”), representing, as applicable, interests in North Square Spectrum Alpha Fund, North Square Dynamic Small Cap Fund, North Square Advisory Research Small Cap Growth Fund, North Square Multi Strategy Fund, North Square Preferred and Income Securities Fund, North Square Tactical Growth Fund, North Square Tactical Defensive Fund and North Square Trilogy Alternative Return Fund, each a series of the Trust.

As counsel for the Trust, we have participated in the preparation of the Post-Effective Amendment to the Trust’s Registration Statement on Form N-1A to be filed with the Securities and Exchange Commission (the “Commission”) to become effective on September 28, 2023, pursuant to paragraph (b) of Rule 485 under the Securities Act of 1933, as amended (the “Securities Act”) (as so amended, the “Registration Statement”) in which this letter is included as Exhibit (i). We have reviewed such documents and made such examination of law as we have deemed appropriate to give the opinion expressed below. We have relied, without independent verification, on a certificate of the Delaware Secretary of State and, as to matters of fact material to the opinion set forth below, inquiries of officers of the Trust and such other documents and certificates as to factual matters as we have deemed necessary to render the opinion expressed herein. We also have assumed that the ownership of all Shares will be duly recorded in the books of the Trust or its transfer or similar agent. The opinion expressed below is limited to the

Delaware Statutory Trust Act, as amended, 12 Del. C. §§ 3801-3863. Members of this firm are admitted to the bars of the State of New York and the District of Columbia.

Based upon the foregoing and subject to the following, we are of the opinion that the Shares, when issued, will be validly issued, fully paid and non-assessable by the Trust.

We note that, pursuant to Section 4.5 of Article IV of the Declaration of Trust, the Trustees have the power, as frequently as they may determine, to cause each shareholder of any particular series or class, to pay directly, in advance or arrears, for charges of the Trust’s transfer, shareholder servicing or similar agent, an amount fixed from time to time by the Trustees, by setting off such charges due from such shareholder from declared but unpaid dividends owed such shareholder and/or by reducing the number of Shares in the account of such shareholder by that number of full and/or fractional Shares which represents the outstanding amount of such charges due from such shareholder.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to our firm as legal counsel for the Trust in the Registration Statement. This consent shall not constitute an acknowledgment that we are within the category of persons whose consent is required by Section 7 of the Securities Act, as amended, and the rules and regulations thereunder.

Very truly yours,
