PRECISION DRILLING CORPORATION
4200~ 150-6th Avenue, S.W.
Calgary, Alberta, Canada 72? 3Y7

Ladies and Gentlemen:

         In connection with the proposed issuance by Precision Drilling
Corporation (the "Corporation"), a corporate body under the laws of
Alberta, of up to an additional 1,518,955 common shares without par value
of the Company ("Common Shares") arising from the exercise of options
granted pursuant to the 2004 Stock Option Plan of the Corporation (the
"Plan"), we have examined such documents as we have deemed necessary or
appropriate in order to express this opinion. This opinion is limited to
the laws of the Province of Alberta, Canada including the laws of Canada
applicable therein. Based on the foregoing, we are of the opinion that;

1.       the Corporation has been duly incorporated and is validly
         subsisting as a corporation under the laws of Alberta and is in
         good standing with respect to the filing of annual returns with
         the office of the Registrar of Corporations for Alberta;

2.       the Common Shares have been duly authorized for issuance by all
         necessary corporate action;

3.       the execution and filing of a subsequent listing application to
         the New York Stock Exchange for the listing thereon of the Common
         Shares has been duly authorized by all necessary corporate action;
         and

4.       upon the issuance of the Common Shares pursuant to the Plan, the
         Common Shares will be validly issued, fully paid and
         non-assessable, and the holders thereof will have no personal
         liability as such under the existing laws of Alberta, which is the
         jurisdiction in which the Corporation is incorporated and which is
         the principal place of business of the Corporation.

         This opinion is rendered to you in connection with the 2004 Stock
Option Plan of the Corporation. This opinion may not be relied upon by you
for any other purposes, or relied upon by you or furnished to any other
person, firm or corporation without our prior written consent.


Yours truly,


/s/ Borden Ladner Gervais LLP
