	Known all by these presents that the undersigned hereby
constitutes
and appoints each of James A. Klein, Jr. and Donald R.

(1) execute for and on
behalf of the
undersigned, in the undersigned's capacity as an officer, director and/or 10%
or
more stockholder
of Adherex Technologies, Inc. (the "Company"), Forms ID, 3, 4 and 5 (and any
amendments
thereto) in accordance with Section 16(a) of the Securities Exchange Act of
1934, as amended
(the "1934 Act") and the rules promulgated thereunder; (2) do and perform any
and all acts for
and on behalf of the undersigned which may be necessary or desirable to
complete
and execute
any such Form ID, 3, 4 or 5 or Schedule (and any amendments thereto) and to
file
timely such
form with the United States Securities and Exchange Commission and any stock
exchange or
similar authority; and (3) take any other action of any type whatsoever in
connection with the
foregoing which in the opinion of such attorney-in-fact may be of benefit to,
in
the best interest
of, or legally required by, the undersigned, it being understood that the
documents executed by
such attorney-in-fact on behalf of the undersigned pursuant to this Power of
Attorney shall be in
such form and shall contain such terms and conditions as such attorney-in-
fact

such attorney-in-fact's discretion.

	The undersigned hereby grants to each such attorney-in-fact full power
and
authority to
do and perform any and every act and thing whatsoever requisite, necessary or

virtue of this power of
attorney and the rights and powers herein granted.  The undersigned
acknowledges
that the
