I must admit when I heard TSN was going to five channels I didn't read the fine print that what it was doing was not really adding three completely new channels per se but was more or less splitting its main TSN channel into four regional channels much like Sportsnet is already structured with Sportsnet Pacific, Sportsnet West, Sportsnet Ontario and Sportsnet East - with often the same live programming being on all four of those channels simultaneously such as when they are showing a live CFL game.
So now here in Southern Ontario it is TSN4 that is the main TSN channel. So anybody with just basic cable gets TSN4 here and not TSN1, TSN3 or TSN5.
TSN1 is the main feed for BC, Alberta and the Yukon, TSN2 is unchanged it is a national channel just as it always has been with different programming, TSN3 is the main TSN feed for Manitoba, NWT and Northern Ontario, TSN5 is the Ottawa Valley region, Quebec and Atlantic Canada.
