      This letter will constitute an opinion upon the legality of the sale by
Flexible Solutions International Inc., a Nevada corporation, and by certain
shareholders of the Company, of up to 1,164,000 shares of Common Stock, all as
referred to in the Registration Statement on Form S-8 filed by the Company with
the Securities and Exchange Commission.

      We have examined the Articles of Incorporation, the Bylaws and the minutes
of the Board of Directors of the Company and the applicable laws of the State of
Nevada, and a copy of the Registration Statement. In our opinion, the Company
has duly authorized the issuance of the shares of stock mentioned above and such
shares when sold, will be legally issued, fully paid, and nonassessable.

                                          Very truly yours,

                                          HART & HART, LLC
