These are the main ones I can think of off my head.
Rogers
Bell Mobility
Telus Mobility
Virgin Mobile Canada
Fido
Solo Mobile
Some of the provincial telco’s have mobility divisions too, but I’m not sure about all of them.
I’ll try and get some descriptions of these later. I have to take the girl to piano right now.
I think for now a one large general Canadian section would do, or 3 sections of the following:
Bell Mobility, Aliant, MTS, Sasktel, Virgin Mobile, Solo, PC Mobile
Telus Mobility, Amp’d Mobile Canada
Rogers Wireless, Fido, 7-11 Wireless
