                OPINION AND CONSENT OF VIRGINIA K. SOURLIS, ESQ.

December 7, 2004

Liska Biometry, Inc.
CANADA

Gentlemen:

I have  acted  as  securities  counsel  for  Liska  Biometry,  Inc.,  a  Florida
corporation  (the  "Company"),  in connection  with the  Company's  Registration
Statement on Form S-8 (the "Registration Statement"), pursuant to the Securities
Act of 1933,  as  amended,  relating  to common  stock to be issued  pursuant to
certain consulting and director agreements (the  "Agreements").  This opinion is
being  furnished in response to Item 601 of Regulation S-K and the  instructions
to Form S-8. I am  familiar  with the  proceedings  to date with  respect to the
proposed Agreements and the issuance of common stock pursuant thereto,  and have
examined such records,  documents and matters of law and satisfied  myself as to
such matters of fact as I have considered relevant for purposes of this opinion.

On the basis of the foregoing, we are of the opinion that:

      1.    The Company is a corporation  duly  organized and existing under the
            laws of the State of Florida.

      2.    The  Agreements  have been duly and validly  authorized and adopted,
            and the shares of common  stock of the Company (the  "Shares")  that
            may be  issued  and sold from  time to time in  accordance  with the
            Agreements  have been duly  authorized  for issuance and will,  when
            issued,  sold and paid for in  accordance  with the  Agreements,  be
            validly issued, fully paid and non-assessable.

The  foregoing  opinion is limited to the federal laws of the United  States and
the  corporate  laws of the State of New  Jersey,  and I am not  expressing  any
opinion as to the effect of the laws of any other jurisdiction.

In  rendering  the  foregoing  opinion,  I have relied to the extent I deem such
reliance  appropriate as to certain matters on statements,  representations  and
other information  obtained from public  officials,  officers of the Company and
other sources believed by me to be responsible.

I hereby consent to the filing of this opinion as an exhibit to the Registration
Statement.  In giving  such  consent,  I do not  thereby  admit that I am in the
category of persons whose consent is required under Section 7 of the Act.


                                     Very truly y ours,


                                     /s/ Virginia K. Sourlis, Esq.
                                     -------------------------------------------
