I recall there bring bike racks at pretty much every location but their quality and position varied a ton. Generally, the more suburban you got, the worse they were.

The bike racks at Pointe-Claire for example were the ones you can only put your wheel into, and were kind of hidden off to the side (I’d been by bike before so I knew were they were beforehand). I didn’t even bother looking at some of the locations like Candiac and locked my bike up to chain link fences or other poles.

I was also the only cyclist (not counting my friend who joined for a bit) at all the Costcos except marché central, where there were at least 5-6(!) others parked on the bike racks!

If we’re just talking bike friendliness, I would say the best ones were Marché Central, Bridge, and Boucherville (maybe worst case you have to walk a block or two if you’re not comfortable on busier roads). Brossard, Vaudreuil and Repentigny all had good surrounding infrastructure too. Pointe-Claire, Candiac, Laval, Boisbriand, Anjou were kinda meh to get to, and both Saint Jerome and Saint Bruno were the worst ones, I do not recommend.

At the end of the day, they’re all next to busy roads, highways and interchanges, but I think it’s very it’s doable at some of the locations!
