You do not have trench war fare everywhere but Winnipeg and Ontario be two large areas.It's over 4200 km from Ottowa to Vancouver. That's more then 5 times the distance from Brussels to Geneva, with no strategic depth. How do you man that trench?
The issue is that in the end Canada will loose but the Americans will need a proper army and have to fight hard to defeat them.
Any American can also be subject to Canadian attacks by partisans.
So the problem Canadians have is the idea that Canadians will not fight for their country or the British empire. That US with their little army (1914) will just walk in and all Canadian will welcome them or run away.
Yes the US has enourmous potential and will defeat Canada but that will not be easy. It will take a year or more. I challenge the Americans to look at the number of soldiers that fought in the WW1.
