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

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 (as to 750,000 shares) and the 1999 Equity
Incentive Plan for Non-Employee Directors (as to 250,000
shares) (collectively, the "Plans" and "Shares").  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 Plans.

     It is our opinion that the Shares, when issued and sold
in the manner described in and required by the Plans, 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.  By
giving the foregoing consent, we do not admit that we are
persons whose consent is required under Section 7 of the
Act.


Very truly yours,

/s/ Law Office of Leonard R. Glass, P.A.
