Flexible Solutions International, Inc.
6001 54 Ave.
Taber, Alberta
Canada  T1G 1X4


     We have acted as legal counsel for Flexible Solutions International,  Inc.,
a Nevada  corporation,  in connection  with the  preparation  of a  registration
statement  on Form  S-4 (the  "Registration  Statement")  to be  filed  with the
Securities  and Exchange  Commission  pursuant to the Securities Act of 1933, as
amended  (the  "Securities  Act").  The  Registration  Statement  relates to the
redomicile  of the Company  from Nevada to Canada (the  "Redomicile")  under the
Canada  Business  Corporations  Act (the  "CBCA").  References in this letter to
"Flexible  Solutions  International  Canada" are to the Company as it will exist
upon completion of the Redomicile under the CBCA.

     In rendering the opinion set forth below we have reviewed:

          (i)  the  Registration   Statement  and  certain   exhibits   thereto,
               including  the  proposed  Articles  of  Continuation  of Flexible
               Solutions International Canada; and

          (ii) Section 187 of the CBCA.

     Based upon and subject to the foregoing,  we are of the opinion that,  upon
the effective date of the Redomicile of the Company under the CBCA,  each issued
and  outstanding  share of  common  stock of the  Company  shall  automatically,
without  any  action on the part of the  Company  or a  stockholder,  become one
validly  issued,  fully  paid and  non-assessable  outstanding  common  share of
Flexible Solutions International Canada.

                                          Very truly yours,

                                          HART & HART

                                          /s/ William T. Hart

                                          William T. Hart
