                OPINION AND CONSENT OF VIRGINIA K. SOURLIS, ESQ.

May 6, 2005

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.
