What do I need to travel to Canada and America?

I'm heading to Toronto and New York in the Summer - can you please advise what I need to travel, ie Visa? We'll be crossing the border on train.
Thanks

Depends on your nationality. If you are either Canadian or American, you just need a passport to cross the border and you do not need a visa. if you are from another country, you will need your passport...and maybe a visa. You can use the site below to learn if you need visas or not. just fill in all the blanks and click for the info.

Also, if you're an American, there's something new called a passport card. It's $45 instead of $100. It's for crossing borders by land and sea, but not by air.

If you're not american, you just need a passport to travel, you don't need a visa unless you plan on staying awhile or working here.

Here's some links that might help for traveling in the US
