American-Canadians can travel with a valid Canadian or U.S. passport.

• passport
• birth certificate
• certificate of citizenship or naturalization
• certificate of Indian status along with photo identification

If you are a US permanent resident, you must carry both proof of citizenship and proof of status in the United States, such as a valid US permanent resident card.
