If this TSN Radio network comes to fruition, I think it would be wise to get some sports stations in some Canadian markets that don't currently have any access to radio sports. Sudbury, for example, has not had any radio sports except for the Sudbury Wolves, which air on a Christian station, CJTK 95.5, since CIGM 790 was replaced by CIGM-FM (Hot 93.5). There has got to be demand for radio coverage of the NHL, MLB, and other sports in a market that size, especially for those who don't have cable or have cable and don't subscribe to channels like Leafs TV.
Other markets lacking a dedicated sports station include Halifax (which had a Team affiliate in the old CJCH 920), Regina, Saskatoon, Kelowna, and Victoria. Although Windsor itself doesn't have one, they have easy access to several sports stations from across the river, and CKLW has local sports.
