This is back in the 1920s, when Canada still practiced the death penalty as well.
If I was the Prime Minister of Canada, first of all... I'd have a much bigger and more powerful industrial economy than what Canada currently has.
And executing a Canadian would cost the USA the entire state of New York, up in flames.
And there would absolutely be no more trade between Canada the USA, ever again.
All the American branded shit would be Catapulted across the border back into the USA.
(after we studied the fucking shit out of it).
