Ladies and Gentlemen:

RE:   REGISTRATION STATEMENT ON FORM S-3
      OUR REFERENCE: CREB013

We have acted as counsel to Workstream Inc., a corporation organized under the
laws of Canada (the "Company"), in connection with the preparation of a
registration statement on Form S-3, (as the same may be amended, the
"Registration Statement") relating to the offer and sale of: 14,167,385 common
shares, without par value (the "Common Shares"), of the Company by certain
selling shareholders named in the Registration Statement; and 2,498,334 common
shares, without par value of the Company issuable pursuant to outstanding
warrants held by certain selling shareholders named in the Registration
Statement (the "Warrant Shares").

In connection therewith, we have examined originals or copies (certified or
otherwise identified to our satisfaction) of the Articles of Incorporation and
By-laws of the Company, the Registration Statement, resolutions adopted by the
Company's Board of Directors with respect to the matters referred to herein, and
other records and documents that we have deemed necessary for the purpose of
this opinion. We have also examined such other documents, papers, statutes and
authorities as we have deemed necessary to form a basis for the opinion
hereinafter expressed. We have assumed the genuineness of all signatures and the
conformity to original documents of all copies submitted to us. As to various
questions of fact material to our opinion, we have relied on statements and
certificates of officers and representatives of the Company and others.

Based upon the foregoing and subject to the assumptions and qualifications
stated herein, it is our opinion that the Common Shares being registered hereby
have been legally issued and are fully paid and non-assessable and that the
Warrant Shares, when issued in accordance with the terms of the underlying
warrants, will be legally issued and fully paid and non-assessable.
