Crossing the Border Into Montana From Canada

Testing is no longer required.

The CDC order requiring persons to show a negative COVID-19 test result or documentation of recovery from COVID-19 before boarding a flight to the United States is rescinded. Air passengers will not need to get tested and show a negative COVID-19 test result, nor show documentation of recovery from COVID-19, prior to boarding a flight to the United States, regardless of vaccination status or citizenship. Of note, CDC’s Order requiring proof of vaccination for noncitizen nonimmigrants to travel to the United States is still in effect.

MONTANA COVID-19 UPDATES

The state of Montana does not require masks and masks are no longer required on public transit in Montana. There may be tribe-specific orders on American Indian reservations.

DOCUMENTATION: UNITED STATES — CANADIAN BORDER CROSSING

When crossing the border, a current passport is required for all travelers. If you are crossing the border with minors, be sure to have notarized travel permission letters from their parents or legal guardians. If you are traveling solo with your children, be sure to bring a note of permission from the other parent. United States citizens under the age of 16 may use their birth certificate or naturalization certificate for travel between the United States and Canada.
