I am familiar enough with the St-Constant area. I heard in Ste-Catherine, on the other side of the 132 there would be a strip club. I could ask a friend of mine about it to know the exact location but I would think it's on Brรฉbeuf near St-Laurent.
Other than that, the only other place I can think about is in St-Philippe (15 south direction NY, next exit after St-Constant/Candiac/Ste-Catherine (rd. 132 jnct)), they use to have the Bar 38. I know it was still open last year, they had ads in the papers. Use to be more than just a strip club from what I heard a long time ago. I am sure it is still pretty much the same today though.
I think I also heard of one strip club in the Chateauguay area but couldn't say where it is or if it is still open.
