POWER OF ATTORNEY

   Know all by these presents that the undersigned hereby constitutes and
appoints each of D. Scott Murray, James A. Klein, Jr. and Donald R. Reynolds,
and each of them acting alone, signing singly, the undersigned's true and
lawful attorney-in-fact to: (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 Schedules 13D or 13G (and any amendments thereto) under Section
13(d) and 16(a) of the Securities Exchange Act of 1934, as amended (the
"1934 Act") in accordance with 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 or Schedule (and any amendments thereto) and to file timely
such Form or Schedule with the United States Securities and Exchange
Commission and any stock exchange or similar authority; and (3) take a
ny 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
may approve in 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 proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might
or could do if personally present, with full power of substitution or
revocation, hereby ratifying and confirming all that such attorney-in-fact,
or such attorney-in-fact's substitute or substitutes, shall lawfully do or
cause to be done by virtue of this power of attorney and the rights and powers
herein granted.  The undersigned acknowledges that the foregoing attorneys-
in-fact, in serving in such capacity at the request of the undersigned, are
not assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 13(d) or 16(a) of the 1934 Act.

   This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file such Forms or Schedules with respect
to the undersigned's holdings of and transactions in securities issued by the
Company, unless earlier revoked by the undersigned in a signed writing
delivered to each of the foregoing attorneys-in-fact.

   IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 20th day of February 2007.

                                          /s/ Jeffrey Solash
