As some of you can read, I've posted about getting prepaid in Canada. While looking I've found pretty much every site that offers service in Canada. What's really cool is alot of the phone will also work in the US as well so it's a pretty sound investment since you can use it as an emergency phone in the states. (To my knowledge this is accurate). Not all of the phones will work but the site are really easy to navigate and find what you want. Here's my list, add more if you know of any!
