Dual Citizenship in Canada: Which Passport to Use at the Border
By Abhi Mehta, Founder of Canada Citizen Center and Immigration Writer
A guide for Canadian dual citizens on which passport to use when travelling. Covers entry and exit requirements for Canada, the U.S., and other countries, with details on procedures, laws, and best practices for smooth travel.
Travelling the world with two passports offers immense freedom, but for Canadian dual citizens, it also brings a critical question: which passport should you use, and when? The answer is not always simple and depends on the citizenship(s) you hold and your destination. Using the correct travel document is essential for smooth border crossings and avoiding potential delays or even denial of entry. As of 2024, Canadian law mandates that Canadian citizens, including those who hold citizenship of another country, must use their Canadian passport to enter Canada when arriving by air.
This requirement, rooted in amendments to the *Customs Act* and the *Citizenship Act*, is a key component of Canada's Electronic Travel Authorization (eTA) system. Since airlines must verify that a passenger has the appropriate document to enter Canada before they can board a flight, the Canadian passport serves as the definitive proof of citizenship and right of entry. For land or sea crossings, the rules are more flexible, but a Canadian passport remains the most reliable and universally accepted proof of citizenship. This guide provides detailed, practical advice for dual citizens on navigating border control in Canada, the United States, and abroad, ensuring you can leverage the benefits of your dual status without encountering procedural hurdles.
The complexities extend beyond Canadian borders. When travelling to the United States, Canadian citizens have unique privileges, but dual citizens who also hold citizenship of a third country must be mindful of U.S. entry requirements. Similarly, entering the country of your other citizenship requires using that country's passport. Understanding these nuances is crucial for any Canadian who holds another nationality, ensuring every international journey is seamless and compliant with the laws of each country you visit.
Key takeaways
- Flying to Canada: You must use your Canadian passport. Airlines are legally required to check for it before you board your flight.
- U.S. Land/Sea Travel: Canadian citizens can enter the U.S. with various documents, including a passport, NEXUS card, or enhanced driver's license. A Canadian passport is the most recommended document.
- Country of Other Citizenship: Always use that country's passport to enter and exit it. This is a common requirement globally to ensure you are treated as a citizen.
- Third-Country Travel: Use the passport that provides the best advantage for entry, such as visa-free access. However, always carry your Canadian passport for consular assistance.
- Proof is Key: Even if not required for entry (e.g., at a land border), a Canadian passport is the only universally accepted and definitive proof of Canadian citizenship abroad.
- Children and Dual Citizenship: The rules apply equally to minor children. If your child is a Canadian citizen, they need a Canadian passport to travel to Canada by air.
Flying to Canada: The Canadian Passport Rule
For Canadian dual citizens, the most important rule to remember is that you must use your Canadian passport to travel to Canada by air. This is a legal requirement under Canadian law. Before the Electronic Travel Authorization (eTA) system was fully implemented on November 10, 2016, dual citizens could often enter Canada using the passport of their other country of citizenship. This is no longer the case.
The primary reason for this change is security and efficiency. Airlines are required to verify that all travellers have the legal authority to enter Canada before they can board the plane. For non-Canadians from visa-exempt countries, this means having a valid eTA. For Canadian citizens, the proof is the Canadian passport. Since Canadian citizens are not eligible for an eTA, attempting to travel on a non-Canadian passport can lead to significant issues at the airport, including being denied boarding.
Immigration, Refugees and Citizenship Canada (IRCC) has made this clear. If you are a Canadian citizen, you cannot apply for an eTA. When you try, the system will recognize your status based on previous immigration or citizenship records. This strict enforcement ensures that border officials have a clear, unambiguous way to verify every individual's right to enter the country.

There is a very narrow exception: American-Canadian dual citizens can continue to use their U.S. passport to enter Canada by air. However, they must carry proper proof of their Canadian citizenship, such as a Canadian birth certificate or citizenship card, to show the airline and border officials. Even for this group, IRCC strongly recommends travelling with a valid Canadian passport for smoother processing.
Crossing the Border by Land or Sea
While the rules for air travel are strict, there is more flexibility when entering Canada from the United States by land or sea. At a land border crossing, a Canadian-American dual citizen can present either their U.S. or Canadian passport. In fact, various documents are acceptable to prove identity and citizenship under the Western Hemisphere Travel Initiative (WHTI).
Here is a comparison of documents that can be used at a land or sea border:
| Document | Admissibility for Canadians Entering Canada | Admissibility for Canadians Entering U.S. | Notes |
|---|---|---|---|
| Canadian Passport | Yes (Recommended) | Yes (Recommended) | The most reliable and universally accepted document. |
| U.S. Passport | Yes (for dual citizens) | Yes | Dual citizens can use their U.S. passport at land borders. |
| NEXUS Card | Yes | Yes | For pre-approved, low-risk travellers. Use at dedicated NEXUS lanes. |
| Enhanced Driver's License | Yes | Yes | Issued by some provinces/states. Contains citizenship information. |
| Birth Certificate | Yes (with photo ID) | No (for adults) | While technically acceptable, it can cause delays. Not WHTI-compliant for U.S. entry for adults. |
For a dual citizen arriving at a land border, the key is to prove Canadian citizenship to the Canada Border Services Agency (CBSA) officer. While a U.S. passport and a verbal declaration of Canadian citizenship might be accepted, presenting a Canadian passport is the most straightforward way to exercise your right of entry under Section 6 of the *Canadian Charter of Rights and Freedoms*. It immediately confirms your status and speeds up the process.
Travelling to Your Other Country of Citizenship
When you travel to the country where you hold your other citizenship, the rule is simple and universal: use that country's passport. Most countries require their citizens to enter and exit using their national passport. Attempting to enter as a foreigner using your Canadian passport can lead to complications.
For example, a Canadian-British dual citizen travelling to the United Kingdom should present their British passport to UK Border Force officials upon arrival. This grants them automatic right of entry and the ability to stay indefinitely. If they were to present their Canadian passport, they would be treated as a visitor, subject to entry clearance, questioning about their intentions, and a limited six-month stay. This could also raise red flags for immigration officials who may have access to data indicating the person is, in fact, a citizen.
This principle applies globally. Whether you are a citizen of India, France, Australia, or any other nation, you are expected to identify yourself as such to their authorities. It simplifies the process and ensures you are afforded the rights (and responsibilities) of a citizen in that country.
Travel to a Third Country
When travelling to a country where you are not a citizen, you have a choice: which passport offers better entry conditions? This is one of the great advantages of dual citizenship. You should use the passport that provides visa-free access or more favorable visa conditions for your destination.
For instance, a Canadian-Chilean dual citizen planning a trip to Russia would find their Chilean passport more advantageous, as Chile has a visa-waiver agreement with Russia, while Canada does not. They would use their Chilean passport to enter and exit Russia.
However, it is crucial to manage your travel documentation carefully. Here's a typical process:
- Check-in: At your departure airport, present the passport you will use to enter your destination country to the airline staff.
- Immigration (Arrival): Present the same passport to immigration officials at your destination.
- Return Journey: When checking in for your flight back to Canada, you will need to show the airline your Canadian passport to prove you have the right to enter Canada.
It is always wise to carry both passports with you, secured in a safe place. Your Canadian passport remains your connection to Canadian consular services. Should you run into trouble abroad, the Canadian embassy or consulate is there to help its citizens, and your Canadian passport is the ultimate proof of that citizenship.

Special Considerations for U.S.-Canada Dual Citizens
Due to the unique relationship between Canada and the United States, there are special considerations for dual citizens of these two countries. As mentioned, a Canadian-American can enter Canada by air using a U.S. passport, provided they also have proof of Canadian citizenship. Conversely, a Canadian citizen can enter the United States for tourism or business without a visa.
However, the United States has a law similar to Canada's regarding its own citizens. The U.S. *Immigration and Nationality Act* requires all U.S. citizens, including dual citizens, to use a U.S. passport to enter and exit the United States. A Canadian-American dual citizen flying from Toronto to Miami must present their U.S. passport to the airline and U.S. Customs and Border Protection (CBP) officials.
This often happens seamlessly at preclearance facilities in major Canadian airports. The traveller will show their U.S. passport to the CBP officer. On the return journey, when checking in for the flight back to Canada, they will show the airline their Canadian passport (or U.S. passport and proof of Canadian citizenship) to confirm their right of entry into Canada.
Renouncing Citizenship and its Consequences
Some individuals may consider renouncing their Canadian citizenship to avoid a particular obligation, such as taxes or military service in another country. Renunciation is a serious and permanent step. Once you renounce your Canadian citizenship, you lose the right to enter and live in Canada freely. You would then be subject to the same visa and entry requirements as any other foreign national.
For example, a former Canadian citizen would need an eTA (if from a visa-exempt country) or a visitor visa to travel to Canada. They would be treated as a visitor, with all the associated limitations. Regaining Canadian citizenship is not a simple process; it requires applying for a grant of citizenship and meeting all the requirements, which can be a lengthy and uncertain procedure.
Frequently asked questions
What happens if I show up at the airport for a flight to Canada with my non-Canadian passport?
You will likely be denied boarding by the airline. Airlines are fined for transporting passengers who do not have the proper documents to enter Canada. The check-in system will flag that you, as a Canadian citizen, require a Canadian passport and are ineligible for an eTA. You may have to reschedule your flight and obtain a Canadian passport.
I am a Canadian citizen but don't have a passport. Can I get a special document to travel?
If you have an urgent, verifiable reason to travel to Canada and cannot obtain a passport in time, you may be able to apply for a "special authorization for dual Canadian citizens." This is granted on a case-by-case basis for situations like a death in the family. It is not a long-term solution, and it is better to always have a valid Canadian passport.
How do I prove I'm a Canadian citizen at a land border without a passport?
You can use other documents like a Canadian birth certificate or a certificate of citizenship, along with a government-issued photo ID like a driver's license. However, this method can lead to more questions and delays. A passport, NEXUS card, or enhanced driver's license is faster and more definitive.
Does my child, who is a dual citizen, need a Canadian passport?
Yes. The rules apply to all Canadian citizens, regardless of age. If your child is travelling by air to Canada, they must have their own Canadian passport. A child's citizenship is separate from their parents', and they need their own travel document.
What if my Canadian passport expires while I am abroad?
You should contact the nearest Canadian embassy, high commission, or consulate to apply for a new passport. Canadian missions abroad can issue new passports and emergency travel documents. It is a good practice to renew your passport well before it expires, especially if you live outside Canada.
Can I use different passports for departure and arrival on the same trip?
Yes, this is standard practice for dual citizens. For example, leaving the UK, you might show your British passport. Arriving in Canada, you must show your Canadian passport. You show the airline the passport that is relevant for the destination to which you are travelling. Always carry both with you.
