Firstly, the big TSN radio station of primary concern to the majority of readers here is safe.... for now. These changes did not effect TSN Radio 1050. But other TSN Radios, including Hamilton's TSN 1150, Vancouver's TSN 1040 and Winnipeg's TSN 1290, are changing formats.
The station formerly known as Hamilton's TSN 1150 is now known as BNN Bloomberg Radio. Vancouver's TSN 1040 is changing formats as well, but not to BNN Bloomberg Radio. Vancouver already has a BNN Bloomberg Radio station at 1410. There's word that Vancouver's 1040 and Winnipeg's 1290 will become Funny-branded stations, much like Hamilton's Funny 820.
