Canadian here, BC to be specific, We have hunting rifles, and plenty of other rifles, not to mention the goddamned natives shoot anything that goes onto the reserves, so we'd do pretty well. In my town we have a very large Steamwheeler that's been beached as a museum with the coal engines intact(the parts may not work now, but we'd be able to recreate them easily), and a great supply of fish from the lakes. Also, orchards, orchards everywhere.
Guns would give us some time to figure shit out and get our magic going, assuming we can learn it in the new place we are in. I don't have guns in my house since I have a kid, but my dad has mine, and even then, I have a BB gun powerful enough to kill dog-sized animals. Pacifistic we may be, but we can defend ourselves.
