He means that while technically possible by simply putting up a Direct TV or other US based satellite dish it is illegal since they are not authorized through rights holders to transmit in Canada. If Fox wants to be seen legally in Canada they have to use one of the Canadian satellite or cable distributors. At the moment although I could be wrong none of the Canadian services carry FNC but of course CNN is everywhere. I'm not sure what is stopping Fox since they certainly have just as much to gain in Canada as CNN. I suppose there might be behind the scenes political pressure to keep Fox out but I've never heard anything about that. A wide array of other US specialty channels exist on the Canadian services although not all of course.
Is it actually illegal to receive Fox on a satellite dish? Or would it just be the satellite owner who would be infringing on intellectual property rights if it intended to transmit unlicensed content to Canada?
[I know this is off-topic on this thread, but intellectual property law is quite interesting.]
