TSN (The Sports Network) in Canada already has 2 feeds, TSN and TSN2. They recently announced the planned roll-out of TSN3, 4 & 5 this fall if approved.
The timing seems a bit strange as they have just lost their contract for most NHL Hockey games, the mainstay of Canadian sports television. The article in last week's Winnipeg Free Press indicates the channels will automatically be available to those who currently have TSN (of course the individual cable companies may have something to say about that.) It also says this will give them the opportunity for more complete coverage of events, specifically mentioning the possibility of offering more than one game on the same draw at curling events. Hopefully it would also mean more complete coverage of Skate Canada International and the Canadian Skating Championships. Got my fingers crossed.
