Hey Dani,
Welcome!!! I am also from Laval and somewhat of a newbie. I say your posts about gun ranges in Laval and had a hard time finding much information about these. Only thing I was able to find somewhat close to Laval is a gun range called ruisseau-noir.ca and it located out the outskirts of Terrebone. I went to check it out and it has a nice outdoor range. Their pistol bay was hard to reach as it was down a slippery mudslide. The range is well hidden in the woods and unless you have a 4x4 it could be hard to reach during rainy season. Winter is off the limits I imagine. Mind that their membership price is quite affordable. I decided to join CRAFM in Lachine. Driving distance is almost the same from Auteil and their range is awesome as well as their staff. Only down fall is that their iron price. Let me know if you found out anything else that may be useful to me as I am pleased to know I have a neighboor with similiar interests!
