Sonny, you can buy the shoulder or belt holster. I tried both and prefer the belt. I found it was easier (for me) to get at if I had to draw. Check the expiry date and buy the spray with 1% capsaicin. That's the highest % you are allowed in Canada.
I've carried bear spray for years and when my old can expired I would take it into the bush with me and practice. The stuff is potent, make sure your target (or position yourself) down wind from you and don't get any on your hands and accidently rub your eye brow like I did. After washing my face in the creek at least a half a dozen times, I still couldn't see good out of one eye for most of the morning.
