I don't think that Canada in your alternative universe would've been worse off than Finland in this one. Finland's neutrality kept it safe ever since the WW2.
Swiss Neutrality did not save them in WW2 either, only German strategic calculus and the idea within the German high command that a mountain campaign would be too costly in military terms. It wasn't their neutrality that saved them, it was military deterrence. Push did NOT come to shove for them.
You cannot seriously assert that if Germany beats the UK and Russia, they will decide to simply leave Switzerland alone?
