Why Did the Power Go Out in Canada?

Here's an interesting thought: The United States and Canada power grids are essentially separate. Electricity, or the sale of it, is money. Countries want to protect those interests. So the big question going around our office is why would Canada be affected something that apparently started in Michigan (according to this story)? I know that there's several officials (county-side at least) that were quite worried last night and waiting for the proverbial shoe to drop in terms of terrorism against this continent. They may say it's not terrorism, but even if was someone hacking into the computer system, that can still be considered a terroristic act. It's an attack.

We'll see what our glorious appointed one feeds us in his next tv/radio appearance.
