Canada Visa and Entry Requirements

Canada is close, familiar and a foreign country, and the border is where those three facts meet. The Canada Border Services Agency publishes its travel document guidance in sections, one for each kind of traveler, and reading the wrong section is the single easiest mistake to make when planning a trip from the United States.

What the CBSA asks of a US citizen

The agency's own words are that to prove your identity and citizenship, regardless of age, it recommends traveling with a valid passport. It then sets out an alternative: documents that show your full name, your date of birth and your citizenship, which may be used in combination if no single document carries all three. The examples it gives include a birth certificate, a certificate of citizenship or naturalization, and a US enhanced driver's license. Where the proof of citizenship has no photograph on it, you may be asked for separate photo identification.

Carry the passport anyway. It is the document every airline understands, it is the one that gets you back into the United States without a conversation, and it removes an entire category of argument at a land crossing. A passport card works at land and sea crossings but not for a flight.

The eTA is not your requirement

The Electronic Travel Authorization appears on the same CBSA page, in the section headed for international travelers other than US citizens and permanent residents. If you hold a US passport this is not the part of the page that applies to you, and a guide written from British or European advice will tell you otherwise, because for those readers the authorization genuinely is the requirement. If you are a US permanent resident rather than a citizen, or you are traveling with someone who is neither, check which authorization applies before booking.

The CBSA carries one warning worth repeating. Companies that offer to help obtain an authorization for a fee do not act for the Government of Canada, and there is one official place to apply. Anyone charging you for an application is not the government.

Passport validity is the length of your stay

The rule for Canada is not the six month rule you may be used to. The FCDO records that to enter Canada a passport must be valid for the length of your planned stay, which is a lower bar than many other countries set. If you are connecting through a third country on the way, check that country separately, because plenty of them do want six months.

The officer decides, on the day

Whatever documents you carry, admissibility is determined on arrival. The CBSA states plainly that a border services officer decides whether you can enter by confirming your identity and your citizenship. That is not a formality to be argued with, and it is worth knowing in advance if you have a criminal record of any kind, including a single old conviction for impaired driving, because that is a question Canada takes seriously and one to resolve before you travel rather than at the booth.

Children, and the paperwork nobody expects

A child traveling without both parents, or with one parent, or with a grandparent, is a routine situation that officers are trained to look at carefully. Carry a letter of consent from the non traveling parent or parents with contact details, and carry the child's own proof of citizenship. NEXUS membership speeds up the crossing for frequent travelers and is worth the application if you expect to cross more than a few times.
