The counter insurgency wars being fought around the world are brutal and morally challenging affairs. The British and Americans have the most experience in this. They can tell you that such warfare is not bloodless and it also comes at a cost. I would agree Canadians do not have the mindset to sustain such warfare overseas. Americans do, but that is because Americans believe in their exceptionalism and in their right to impose their way of life on others. The British, on the other hand, have their Empire, and lots of experience in keeping it together with force. 

Canadians do, however, undertake secret missions all the time to kinetically remove individuals. This is very far under the radar and has been for decades. We do this for mining companies in the main, but also with allies (US, Australia, UK).
