This is a great neighborhood hardware store. It's actually called Quincaillerie Delorimier, but it's affiliated with the Rona chain. I live a block away and have conducted extensive renovations over several years with the help of this place. Of course I try to buy as much materials as I can at Reno Depot or Home Depot. The big boxes are cheaper, but if I just need a small item I can save myself a time-consuming car trip by walking down to Rona.
They have a pretty complete selection of building supplies and tools, even if you are paying maybe 50% more than the big boxes.
They have a large staff of reasonably knowledgeable young guys who stand around waiting to answer your questions. This is a big plus when you are trying to solve some home repair problem.
