Thanks guys for all this - I've been away so have only just caught up. This situation is more than a little depressing it seems, as far as handguns go, and I think I'll have to give it a pass and stick to long guns.
But I agree with Halftail's various points. And as far as muzzleloading flintlock long guns goes, Canada is still gloriously free of paperwork - I can buy or build a gun, buy ball and powder (which is classified as an explosive, not as 'ammunition'), and shoot target or varmint on my own land, without having to get a permit or register anything. The only restrictions where I live are imposed by the local county which does not allow recreational shooting on Sundays or from half hour before dawn to half hour after dusk. Pretty good if you ask me.
