As a fill in transmitter with limited power, it would have no effect here as CHYM-FM from the Kitchener Waterloo area is a bit choppy at ground level and rock solid from my 11th floor apartment looking northwest.
I would have preferred they buy out a major player with the amount of similar content musically being currently broadcast in Toronto across many stations, but that's another topic.
One thing with low powered stations, you need a good radio to receive them as cheaper receivers tend to "cave in" when confronted with the tough radio environment that downtown Toronto is.
