Baggio Cycle closed in the early 1980s. I did not move to Montreal until 2003, but my wife grew up in Montreal and bought her bike at Baggio when she was young. Their house brand was called Torpado. You still see a fair number of these floating on the streets of Montreal with a various mixture of quality components. The shop is now called Dumoulin Cycles and I think that was probably the end of the Italian importation era for the shop. I looked at many different Torpados and none seem to really match with this bike in terms of construction.
Bloor cycle was out of Toronto. They also are now closed. Their house brand appears to have been called Santini. I have not seen many of them in Montreal.
