Ladies and Gentlemen:

         We are furnishing this opinion of counsel to WaveRider Communications
Inc., a Nevada corporation (the "Company"), for filing as Exhibit 5.1 to the
Registration Statement on Form S-2 (the "Registration Statement") filed by the
Company with the Securities and Exchange Commission under the Securities Act of
1933, as amended, relating to the issuance of 21,170,142 shares of the common
stock of the Company, $.001 par value per share (the "Shares").

         In arriving at the opinions expressed below, we have examined and
relied on the following documents: (a) the Articles of Incorporation of the
Company, as amended; (b) the Bylaws of the Company; (c) the Registration
Statement and (d) the records of meetings and consents of the Board of Directors
and stockholders of the Company provided to us by the Company. In addition, we
have examined and relied on the originals or copies certified or otherwise
identified to our satisfaction of all such corporate records of the Company and
such other instruments and other certificates of public officials, officers and
representatives of the Company and such other persons, and we have made such
investigations of law, as we have deemed appropriate as a basis for the opinions
expressed below.

         Based upon the foregoing, and subject to the qualifications set forth
herein, we are of the opinion that when the Registration Statement shall have
become effective and when the Shares are purchased as described in the
Registration Statement, the Shares will be validly and legally issued, and fully
paid and nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. This consent shall not be deemed to be an admission that
counsel is an expert within the meaning of Section 7 of the Securities Act of
1933, as amended.

         This opinion is being delivered and is intended for use solely in
regard to the transactions contemplated by the Registration Statement and may
not be used, circulated, quoted in whole or in part or otherwise referred to for
any purpose without our prior written consent and may not be relied upon by any
person or entity other than the Company, its successors and assigns. This
opinion is based upon our knowledge of law and facts as of its date. We assume
no duty to communicate to you with respect to any matter which comes to our
attention hereafter.

                                                     Very truly yours,

                                                     FOLEY HOAG LLP
