Safety Dance.
Men Without Hats (probably my favourite band from Montreal) had a number of singles that got respectable airplay on Canadian radio: "Pop Goes the World," "Moonbeam," and "Hey Men," for example.
Broadcast regulations in Canada that require a certain percentage of music to be Canadian content, has led to what's been called a music industry of "hothouse flowers"—many bands that thrive inside Canada's borders but are virtually unheard of anywhere else. (How many Platinum Blonde singles can you name?) I suspect the Internet has eroded this, somewhat.
