There's a couple of services out there that help map which OTA stations people can access. Quebec City & Winnipeg aren't that close to any US population centres so they don't get nearly as many stations as places like Montreal or Vancouver. I was quite sad when I got to Calgary and couldn't pick up any US signals. That being said, the CRTC has some restrictions on these kinds of signals. You aren't allowed to import DirecTV/Dish equipment. Shaw Direct used to advertise to snowbirds that they could bring their dishes to their US homes but got their hands slapped by the FCC and stopped.
