     RE:  OFFERING OF SHARES OF COMMON STOCK OF ARDIS TELECOM & 
          TECHNOLOGIES, INC.

Ladies and Gentlemen:

     On April 9, 1999 ARDIS Telecom & Technologies, Inc., a Delaware 
corporation and successor by merger to Canmax Inc. (the "Company"), expects 
to file with the Securities and Exchange Commission Post-Effective Amendment 
No. 1 to Registration Statement on Form S-3 (the "Registration Statement") 
under the Securities Act of 1933, as amended (the "Act"). The Registration 
Statement relates to the offering (the "Offering") of up to 863,364 shares 
(the "Registrable Shares") of the common stock, $.001 par value per share 
(the "Common Stock"), by certain stockholders of the Company (collectively, 
the "Selling Stockholders"). This firm has acted as your counsel in 
connection with the preparation and filing of the Registration Statement, and 
you have requested our opinion with respect to certain legal aspects of the 
Offering.

     In rendering our opinion, we have examined and relied upon the original 
or copies, certified to our satisfaction, of (i) the Certificate of 
Incorporation of the Company, as amended through the date hereof, (ii) the 
Bylaws of the Company, as amended through the date hereof, (iii) copies of 
various resolutions of the Board of Directors of the Company and (iv) such 
other documents and instruments as we have deemed necessary.

     In our examination, we have assumed the genuineness of all signatures 
and the authenticity of all documents submitted to us as originals, and the 
conformity to original documents of all documents submitted to us as 
certified or reproduction copies. As to various questions of fact material 
to this opinion, we have relied upon representations or certificates of 
officers or directors of the Company and upon documents, records and 
instruments furnished to us by the Company, without independent check or 
verification of their accuracy.



     Based on the foregoing examination and subject to the comments and 
assumptions set forth below, we are of the opinion that the Registrable 
Shares to be sold by the Selling Stockholders in the Offering were validly 
issued, are fully paid and are nonassessable.

     This opinion is limited in all respects to the General Corporation Law 
of the State of Delaware as in effect on the date hereof. For purposes of 
this opinion, we have assumed that the shares of common stock of Canmax Inc. 
exchanged for the Registrable Shares upon the merger of Canmax Inc. into the 
Company were validly issued, full paid and nonassessable under Wyoming law.

     We bring to your attention the fact that this legal opinion is an 
expression of professional judgment and not a guarantee of result. This 
opinion is given as of the date hereof, and we assume no obligation to update 
or supplement such opinion to reflect any facts or circumstances that may 
hereafter come to our attention or any changes in laws or judicial decisions 
that may hereafter occur.

     We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and to the use of our name under the caption "Legal 
Matters" in the Prospectus forming a part of the Registration Statement. In 
giving such consent, we do not admit that we come within the category of 
persons whose consent is required by Section 7 of the Act or the rules and 
regulations of the Securities and Exchange Commission thereunder.

                                       Very truly yours,

                                       /s/ ARTER & HADDEN LLP
                                       ----------------------
