Dear Sir or Madam:


Re:  Registration Statement on Form S-8 Relating to the Executive
     Stock Option Plan (the "Plan")
     ------------------------------------------------------------

Reference is made to the above-captioned Registration Statement on Form S-8
(the "Registration Statement") filed by DataMirror Corporation (the "Company")
on the date hereof with the Securities and Exchange Commission under the
Securities Act of 1933, as amended, relating to the registration of a total of
792,500 Common Shares of the Company issuable pursuant to options granted under
the Plan (the "Shares").

We have examined, and are familiar with, and have relied as to factual matters
solely upon, a copy of the Plan, the currently effective articles and by-laws
of the Company, resolutions of the Board of Directors and the shareholders of
the Company and originals or copies of such other documents, certificates and
proceedings as we have deemed necessary for the purpose of rendering this
opinion.

In our examinations, we have assumed the genuineness of all signatures, the
legal capacity of all individuals, the authenticity of all documents submitted
to us as originals and the conformity to the originals of all documents
submitted to us as certified, conformed, telecopies, facsimiles or photostatic
copies.



Based on the foregoing, we are of the opinion that the Shares have been duly
authorized and, when issued and paid for in accordance with the terms of the
Plan and the terms of any agreement relating to such issuance, will be validly
issued and fully paid and non-assessable.

We acknowledge that we are referred to in Item 8 of the Registration Statement
and we hereby consent to the use of this opinion and consent for filing with
the Registration Statement as Exhibits 5.1 and 23.1 thereto.

This opinion is rendered solely for the benefit of DataMirror Corporation and
may not be used or relied upon for any other purpose or used or relied upon by
any other person without our prior written consent.


                                  Yours truly,

                                  (signed) BLAKE, CASSELS & GRAYDON LLP



                                                              EXHIBIT 23.2
