For what it's worth (not much at this point I would guess), TSN 1050 is now also broadcast from the CN Tower on the HD radio signal of 104.5 CHUM-FM.

You need to have an HD radio receiver to get it. The cheapest new ones (portable or for cars) now seem to be in about the $70 to $100 range.
I got a used one like this cheaper on ebay last year, although it appears this brand and model is no longer available.

The sound quality is a little better, as is reception indoors and on buses etc., and may be better at night and in places where the TSN 1050 AM signal is weak or does not reach.
