There are two types of modern gas canisters for backpacking (see Backpacking Gas Canisters 101 for further information).

Generally, stoves built for one type of canister only work with that type of canister. For example, Camping Gaz stoves generally only work with Camping Gaz canisters. There are a few exceptions. Unfortunately, those exceptions aren't very lightweight.

However, there is a relatively lightweight stove that will use either Camping Gaz or threaded canisters. Check out The SuperGnat.
