We are the former independent auditors for Plymouth Rock Technologies Inc.

The Company provided us with a copy of the disclosures in its Current Report on Form 20-F and for the year ended November 30, 2020 (the “Form 20-F”) and requested that we furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not we agree with the statements in Item 16F of the Form 20-F, and if not, stating the respects with which we do not agree.

Yours very truly,
