there are a few places that hoard really nice crap but the owners are really surly and don't like selling said hoarded crap. That being said La Bicicletta, High Park Cycles and Racer Sportif all have really nice stuff.

Apart from that toronto's largest bike stores are Urbane Cyclist, Sweet Pete's Cyclepath, and Duke's Cycle. Cavern Cycles and La Carrera are the two shops that specialize most in fixed gear bikes and the guys who work them are great.

We can offer more in depth reviews and comparisons in the Toronto thread though as we have nothing better to discuss
