If I set up Plex TV, will I only have access to live tv from local over the air broadcasts?

I am in Toronto, Canada and would like to set up Plex TV to have access to Live TV for the cable networks in the area (Rogers /Bell Digital). Is this at all possible? I just want to have access to all of the sports channels.

If Ontario is like Quebec, no. The only way to get cable tv in the DVR is with a hdhomerun prime, which uses cards from tv providers to know what channels you can see… And as far as I know, that is US only/not in Canada.
