Question: American visiting Canada, and vice versa

For us Canadians, we simply need a passport, a driver's license, a birth certificate, and car insurance (if you're driving). If you're flying, you don't need proof of car insurance.<br><br>What about Americans? I'm coming to realize that Americans don't even need their actual passport - they just need a photocopy of it,, and an enhanced driver's license. I've even heard of people walking in with *just* a photocopy of their enhanced driver's license. It doesn't even have to be the real license, just a photocopy of it. ?
