Dear Sirs/Mesdames:

We refer to the prospectus of Advantage Energy Income Fund (the "Trust") dated
January 31, 2005 relating to the qualification for distribution of 5,250,000
trust units of the Trust (the "Prospectus").


We consent to the use through incorporation by reference in the Prospectus of
our report dated November 12, 2003 to the directors of MarkWest Resources Canada
Corp. on the following financial statements:

         Balance sheet as at December 31, 2002;
         Statements of earnings, retained earnings (deficit) and cash flows for
         the year ended December 31, 2002.

We report that we have read the Prospectus and have no reason to believe that
there are any misrepresentations in the information contained therein that are
derived from the financial statements upon which we have reported or that are
within our knowledge as a result of our audit of such financial statements.

 This letter is provided solely for the purpose of assisting the securities
 regulatory authorities to which it is addressed in discharging their
 responsibilities and should not be used for any other purpose. Any use that a
 third party makes of this letter, or any reliance or decisions made based on
 it, are the responsibility of such third parties. We accept no responsibility
 for loss or damages, if any, suffered by any third party as a result of
 decisions made or actions taken based on this letter.

 Yours truly,

"Signed"
