CAR 21 Subpart P details the requirements for the issue and renewal of a Permit to Fly. CAR GEN Subpart D details the requirements for airworthiness, maintenance and arrangements for the release of aircraft for flight operating under a Permit to Fly.
A Permit to Fly can be granted to the operator of an aircraft only for the purpose of flying the aircraft to a place where maintenance, permanent repair or alterations are to be performed; or for the purpose of conducting a flight associated with the approval of a modification.
The application for a Permit to Fly can be made by using FORM SM 12.
