Got it! This is the Black Market Vintage Clothing Store at Queen & John in Toronto
319 Queen Street West.
Must have driven past here a hundred times, funny, the place just doesn't stand out. They need to do something with their decor I guess.

I guess the book store that Charlatan was referring to was Bakka, on the north side of Queen. It's gone now, moved down further to West Queen West, and is called Bakka Phoenix.
The building beside where Bakka was used to be the exterior that was the Lawyer's office in that wonderful '80's CBC offering of Street Legal, which for some reason is now broadcast on Bravo at around 7 AM weekdays.
Since Charl is gone, I'll find a pic and post....
