Canada will fight alongside democracies, dealing with threats to international security, and sometimes for humanitarian purposes that overlap with security interests. I don't think Canada has the ability to dedicate lots of resources to every humanitarian crisis. It's only going to happen when there's a confluence between security interests and humanitarian interests.
Libya, for instance, was both. For Canada, the stake in Libya was NATO. That was a security interest. It was also essentially an R2P mission, even if people didn't call it that. But Canada can't dedicate all of its fighters and all its planes and all of its ships to everything that goes on in the world. It has to make choices, and the choices will be when the humanitarian interests are coincident with security interests, not when they're off on their own.
