I don't know about elsewhere in Canada, but here, Bell and Rogers compete directly in the mobile space, and Bell competes directly with cable, and all of those options have multiple resellers at half the price, thanks to CRTC.

Are the prices the lowest in the world? No. Can you tell a company to fuck off? Yes, you can.

I don't know. The Canada described by OP might be a foreign land compared to the part of Canada I know.
