By execution hereof, the undersigned acknowledges receipt of the Prospectus dated , 2000 (the "Prospectus") of GT Group Telecom Inc.

The terms of the Exchange Notes are identical in all material respects (including stated amount at maturity, interest rate and maturity) to the terms of the Outstanding Notes for which they may be exchanged pursuant to the Exchange Offer, except that the Exchange Notes will have been registered under the Securities Act of 1933, as amended, and, therefore, will not bear legends restricting the transfer thereof. This Letter of Transmittal is to be used by Holders (as defined below) if: (i) certificates representing Outstanding Notes are to be physically delivered to the Exchange Agent herewith by Holders; (ii) tender of Outstanding Notes is to be made by book-entry transfer to the Exchange Agent's account at The Depository Trust Company ("DTC") by any financial institution that is a participant in DTC and whose name appears on a security position listing as the owner of Outstanding Notes (such participants, acting on behalf of Holders, are referred to herein, together with such Holders, as "Acting Holder"); or (iii) tender of Outstanding Notes is to be made according to the 2 guaranteed delivery procedures. DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

To tender Outstanding Notes through ATOP, the electronic instructions sent to DTC and transmitted by DTC to the Exchange Agent must contain the character by which the participant acknowledges its receipt of and agrees to be bound by this Letter of Transmittal. Unless the context requires otherwise, the term "Holder" for purposes of this Letter of Transmittal means: (i) any person in whose name Outstanding Notes are registered on the books of Group Telecom or any other person who has obtained a properly completed bond power from the registered Holder or (ii) any participant in DTC whose Outstanding Notes are held of record by DTC who desires to deliver such Outstanding Notes by book-entry transfer at DTC.

The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as the true and lawful agent and attorney-in-fact of the undersigned (with full knowledge that said Exchange Agent also acts as the agent of Group Telecom and as Trustee under the Indenture for the Outstanding Notes and the Exchange Notes) to cause the Outstanding Notes to be assigned, transferred and exchanged. The undersigned represents and warrants that it has full power and authority to tender, exchange, assign and transfer the Outstanding Notes and to acquire Exchange Notes issuable upon the exchange of such tendered Outstanding Notes, and that, when the same are accepted for exchange, Group Telecom will acquire good and unencumbered title to the tendered Outstanding Notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim. The undersigned also warrants that it will, upon request, execute and deliver any additional documents deemed by the Exchange Agent or Group Telecom to be necessary or desirable to complete the exchange, assignment and transfer of tendered Outstanding Notes. The Exchange Offer is subject to certain conditions as set forth in the Prospectus under the caption "Exchange Offer -- Certain Conditions to the Exchange Offer". The undersigned recognizes that as a result of these conditions (which may be waived, in whole or in part, by Group Telecom) as more particularly set forth in the Prospectus, Group Telecom may not be required to exchange any of the Outstanding Notes tendered hereby and, in such event, the Outstanding Notes not exchanged will be returned to the undersigned at the address shown below the signature of the undersigned.

By acknowledging that it will deliver and by delivering a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes, the undersigned is not deemed to admit that it is an "underwriter" within the meaning of the Securities Act. For purposes of the Exchange Offer, Group Telecom shall be deemed to have accepted validly tendered Outstanding Notes when, as and if Group Telecom has given oral or written notice thereof to the Exchange Agent and complied with the applicable provisions of the Registration Rights Agreement.

All authority conferred or agreed to be conferred by this Letter of Transmittal shall survive the death, incapacity or dissolution of the undersigned and every obligation under this Letter of Transmittal shall be binding upon the undersigned's heirs, personal representatives, successors and assigns.
