French Canadians are not "frogs".

That is the French. The French Canadians are "toadies".

If you watch any sea-faring film (like A&E's Horatio Hornblower), you'll see that even back in the late 1700's, the Frenchies were referred to as "Frogs" by the English sailors. Even the French forces fighting in the New World were called "Frogs".
