The site is not really well. I find nothing on it. But inside, you have a room full of leather and latex wearing.
You have Priape at St-Catherine street:

Its a 2 floors shop. The underfloor is a room full of leather latex and others things.
But for me, the best of the best is a online shop. Its Skinz.
