A lot of opinion over the fact that Canada, in its entire history, has only used conscription twice and it was for two major conflicts

I never claimed otherwise.

The arguments you are attempting to make are moot when considering this very big fact

Not really. It has nothing to do with how many times Canada has used conscription.

If it is hard to imagine a war Canada would be fighting to defend itself worry not because the arctic is thawing and a few countries are salivating over it.

I imagine if a straight up war of conquest over Canada's north happened, more Canadian's would be willing to help with that and conscription would probably be unnecessary. That highly depends on our feelings of national unity, which to me seem to be at an all time low (in my lifetime). I feel that any attempt by the federal government to introduce compulsory military service would be disastrous as there's high tensions when it comes to the prairie provinces and Quebec. Why would they consent to their peoples being forced to fight and die for a united Canada when they don't feel like Canada should be united?

I don't know how they would plan to address this, but I feel Canada would need a large reason to be unified if they were to introduce conscription, and the current climate isn't it.
