To be safe, I would only use FT-4 rated wiring, if I were you.
On the City of Calgary web site, they say that permits are required, but I am guessing this only applies to commercial installations: (pg.23+)

This Electrical Inspection Section is enforcing permit requirements for all communication installations being done in the city of Calgary. As per The City of Calgary By-law 55M89, a Communication Permit is required for the installation of communication systems. Inspectors are instructed to ensure permits are obtained for the installation of communication systems. Provisions have been made for the registering, licensing, and obtaining of Communication permits for companies involved in the communication business. In reference to the Canadian Electrical Code (20th Edition), communication system means
“an electrical system whereby voice, sound, or data may be received and/or transmitted, and includes telephone, telegraph, data communications, inter-communications, paging systems, wired music systems, and other systems of similar nature. It excludes alarm systems such as fire, smoke, or intrusion, radio and television broadcast communication equipment, closed circuit television, or community antenna television systems”
Any hybrid system which connects different types of systems together (i.e., an intrusion alarm system connected to a telephone system) may require a permit. Consult with the Electrical Inspection Section to determine if a permit is required for these types of installations.
If the communication installation is done in conjunction with the main electrical installation, then both installations must be listed on the same permit.
