I know that canisters are required in several locations, but the op never mentioned he hikes those areas. I live in Az, so I don't know anyone who uses them or needed one. I am just surprised to hear that losing it is a regular problem, versus a once in a long time problem. I would get a silnylon or mesh bag big enough to hold the canister and hang it. Even if it is just from a branch...or you can get a portable car alarm and use your key fob.
