Re:  Registration Statement on Form S-8 Under the Securities Act of 1933

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-8 to be filed
by you with the Securities and Exchange Commission on or about the date
hereof (the "Registration Statement") in connection with the registration
under the Securities Act of 1933, as amended, of the 2000 Flexible Stock
Plan (4,500,000 shares).(the "Plan" and "Shares" as appropriate).  As
legal counsel for CTC Communications Group, Inc., we have examined the
proceedings taken and are familiar with the proceedings proposed to be
taken by you in connection with the issuance and sale of the Shares
pursuant to the Plan.

     It is our opinion that the Shares, when issued and sold in the manner
described in and required by the Plan, will be legally and validly issued,
fully-paid and non-assessable.

     We hereby consent to the use of our opinion as herein set forth as an
exhibit to the Registration Statement and to the use of our name under
Item 5, Interest of Named Experts and Counsel, in the Registration
Statement.  Leonard R. Glass, Esq., a member of this firm, is a
stockholder of CTC Communications Group, Inc.


               Very truly yours,
