Beginning on January 1, 2008, travellers to and from Canada will need to have a passport or "other secure, accepted document" to enter or re-enter the United States.  I know this answer doesn't directly address you question of going TO Candada, but you will soon need a passport to RETURN from Canada.

you have to get a passport from your own country.  Do you have a passport to be in the US?

#1\nProof of your U.S. citizenship such as your U.S. passport (For information on obtaining a U.S. passport, check with one of the regional passport agencies located throughout the U.S.) or certified copy of your birth certificate issued by the city, county or state in the U.S. where you were born. If you are a naturalized U.S. citizen and do not have a passport, you should travel with your naturalization certificate. A driver’s license, voter’s registration card or Social Security card is NOT valid proof of citizenship.\n#2\nPhoto identification, such as a current, valid driver’s licens\n(Note: after December 31, 2006 the following applies):\nTravelers to and from Canada will be required to have a U.S. passport or other secure, accepted document to enter or re-enter the United States.  For land border crossings to Canada, other documents that we anticipate will be acceptable are NEXUS and FAST program cards.  No other document is currently available that will be an acceptable substitute for a U.S. passport, NEXUS or FAST card.

In the past few days they raised the ID requirements for leaving and entering the country.  I'm betting that everybody will need a passport.

In Canada the law is that you cannot travel if you have "committed an offense for which a pardon has not been granted" (I got my passport a while ago)

Yes you can. You will have to get a British Passport and an American Passport though.  The two countries have an agreement regarding dual citizenship.  You have a birth right to do so.    Mine is Canadian and UK

To elaborate on a previous answer, any Canadian consulate should have the resources to do this for you as long as you have all the relevant data handy (like identification).  You can find all relevan Canadian passport information at the site below.

Currently, as of today, YOU DO NOT NEED A PASSPORT FOR TRAVEL BETWEEN THE USA MEXICO. You can go anywhere in MEXICO without a passport. You will need your driver's license and your birth certificate (not a copy). \n\nHOWEVER, with that said, starting January 1, 2008 YOU WILL.\n\nHere is the information from the USA Government:\n\nThe Intelligence Reform and Terrorism Prevention Act of 2004 requires that by January 1, 2008, travelers to and from the Caribbean, Bermuda, Panama, Mexico and Canada have a passport or other secure, accepted document to enter or re-enter the United States. In order to facilitate the implementation of this requirement, the Administration is proposing to complete it in phases following a proposed timeline, which will be published in the Federal Register in the near future. \n\nThis is a change from prior travel requirements and will affect all United States citizens entering the United States from countries within the Western Hemisphere who do not currently possess valid passports. This new requirement will also affect certain foreign nationals who currently are not required to present a passport to travel to the United States. Most Canadian citizens, citizens of the British Overseas Territory of Bermuda, and to a lesser degree, Mexican citizens will be affected by the implementation of this requirement. \n\nHere is the link for the U.S. Department of State with the above information:  http://travel.state.gov/travel/cbpmc/cbpmc_2223.html\n\n\nHere is the website for you to apply for an American Passport:\nhttp://travel.state.gov/passport/get/first/first_832.html\n\nYou can print out and complete the application before you go to apply. \n\nYou have to submit your passport application at the post office. \n\nBe aware not all post offices accept passport aplications and some only do it certain days and certain times of the day. Here is a link for you to find out the nearest place you can apply: \n\nhttp://iafdb.travel.state.gov/

Assuming you are in the country already, you just need government issued ID (passport) and your visa number.

To enter back into the US from Mexico you need your US passport starting Dec. 31, 2006.\n\nAnd from Canada you will need the US Passport starting Dec. 31st 2007.

I'm sorry I can't answer your question very well but I know that there are states out there that do.  In North Carolina, for example, you have to prove residency and identity.  It would be really hard, almost impossible, in fact, to have the items on their list of accepted documents unless you are legally in the country.  If you weren't born in the US or Canada then you have to have multiple things like valid passports and school records.

You'll have to get a passport if you're not coming here by January. Starting before the end of January of 2007 ALL people entering the United States, even citizens, will be required to show a passport at all ports of entry. That includes by foot, plane, train, car or boat. \n\nAmerica is a beautiful country with more diverse nature than anywhere in the world. In California you can be in the snow in the mountains, surfing a wave in the ocean and camping in the desert in less than a week.

You just cross over the boarder into British Columbia, going thru Canadian Customs. Just make sure you have some photo ID on you. Have fun!

when you enter the USA , if you are a US citizen, the law requires you to identify yourself as a US citizen.\n\nAs far as traveling to Canada or another country it's your choice what passport you want to use but when you enter the USA you need to use your American passport.\n\nCitizens of Spain do not require a visa to visit Canada as a tourist.
