Something I’ve wondered about for a while: Canada is our No. 1 source of oil imports. And Canadian tar-sands are often cited by energy optimists as a virtually unlimited source of future oil.

But, um, has anyone asked Canada about this? Or rather, asked Canadians, as opposed to the Canadian government? ‘Cause it seems like a pretty raw deal for them. Extracting tar-sands oil is horrifically destructive to the environment and the workers involved. And because of NAFTA, Canada is stuck exporting most of it to us, meaning they’re fueling our dreams of empire at the possible expense of their own future energy security. Furthermore, in times of energy scarcity, being a fruitful source of oil immediately contiguous to the world’s largest consumer of oil — and also its most powerful, hyper-militarized country — might prove to be a little, ahem, awkward.

Anyhoo, Oil Drum has a thread going about all this, playing off this Canadian think-tank report (PDF), which raises all the above concerns. Lots of interesting stuff.
