What is most obvious is that Assad will not just "go" because someone halfway around the world "calls" for it. It would take many bombs and troops on the ground. In the aftermath, it would probably take decades of occupation by more troops on the ground. 

Trudeau refuses to increase military spending above 1.2%, even as the rest of NATO who are not already over the 2% bottom limit are working towards it. So our contribution would be a handful of decades-old planes and at best a bunch of overweight troops (sorry, that is the state of our military readiness -- a known problem). 

Now that deficits are already 300% of the planned "modest deficits," there is no room for improvements in the budget either. So this "calling for..." amounts to about the same as wishing for your fairy godmother to wave her wand and make Assad disappear.
