Despite the warrior rhetoric from some of our politicians, Canada is not a robust military power. We do, however, have experience and credibility — although it has been diminished recently — in diplomacy, humanitarian assistance and the resettlement of refugees.
There's about 26 or 27 nations in the anti-ISIS coalition, and about half of them are dropping bombs. IMHO Canada would be more useful to what is clearly going to be a multi-generational conflict by being one of the coalition members not currently dropping bombs. There will be lots of roles to play in the years and yes decades ahead.
