What can I use with a driver's license to prove US citizenship besides a birth certificate traveling to canada

Friend of mine wants to travel up for christmas, and has a driver's license, and social security card, and a few other documents I believe, but no birth certificate... what can he use in its place, if traveling by greyhound from Alabama to Kitchener?

passport or a NEXUS I.D. heres the link on how to get that

also a naturalization certificate.

If you're driving in, all you need is a drivers' license. At least if you're driving in a car that's the rule, until next June, so I assume a bus is the same. You need a passport if you land at an airport there, but not for driving in. I'll they've ever asked of me is my drivers' license.

Oh, and a drivers' license does not prove citizenship. People with greencards can get drivers' licenses (but it does show that you live in the US).

social security card and license should be enough

passport

Entering Canada (or the US, or Mexico), you are required to provide photo ID (which may be passport, US or Canada driver's license, or military ID).

You are ALSO required to provide proof of citizenship (which may be passport, birth certificate, and/or naturalization papers).

Before 01 January 2008, the passport is NOT required if traveling by land or sea AND the individual is a citizen of Canada, US, or Mexico (regardless of which country you enter).

After 01 January 2008, CANADA (and possibly Mexico) will require passports for individuals to enter.

To enter the US, an individual *may* require them as well; after 31 January 2008, the phase-in will begin in earnest, finishing by June 2008.

All three countries WILL DEFINITELY require passports by June 2009, regardless of mode of travel. This is part of the Western Hemisphere Travel Initiative (WHTI).

In certain instances, there are other identifications available for frequent "trusted travelers" (NEXUS, SENTRI, and FAST are examples).
