Dual citizenship - pros and cons Print E-mail

When deciding on dual citizenship, there are several issues that CIC urges you to consider:

Military service: Many countries still have compulsory military service. If you are a citizen, and you meet other conditions, you may be legally required to register for military service and to respond to call-up orders. This legal obligation may exist even if you do not reside in the country of your second citizenship. Your obligations could be enforced even if you're just visiting at some point in the future.

Taxation: Taxation arrangements between countries are complex. If you have dual citizenship, you may encounter obligations in both countries. These obligations should be discussed with your financial and/or legal advisers.

Travel: If you travel with two passports, you could be subject to increased scrutiny by immigration and security officials. You could be questioned about missing entry or exit stamps, as well as your reason for having two travel documents. In some countries, possession of a second passport could result in its confiscation or a fine. You may even be prevented from leaving the country.

Marriage, divorce and child custody: Canada recognizes the legality of marriages performed in other countries. However, marriages performed in Canada may not always be considered legal in other countries. Similarly, divorce and child custody documents issued by Canadian courts may not be recognized.

Gay marriages: Canada is one of very few countries to legalize gay marriages. When travelling to many other countries (even across the border to the US), there might be issues that arise on any number of levels.

Education: If the country of your second citizenship provided you with free education, especially at the secondary or professional level, you may be held liable for reimbursing the costs. This is particularly the case if you obtained the education outside the country of your second citizenship.

Inheritances: Some countries may not permit the transfer of inheritances to nationals with a second citizenship.

CIC says preparation and knowledge are the keys to avoiding problems associated with dual citizenship. If you have any questions or concerns, contact the country of your second citizenship before you travel.

Formally establish whether you are subject to any outstanding obligations such as military service, taxation or education repayment. This information should be confirmed in writing. Carry this document with you when you travel - some dual citizens have received inaccurate or incomplete information from officials representing the country of their second citizenship.

If you do run into problems abroad because of your dual citizenship, contact the nearest Canadian embassy or consulate immediately. If you're unable to make contact and require immediate assistance, place a collect call to the Operations Centre, Consular Affairs Bureau, Foreign Affairs Canada, at (613) 996-8885, or send an e-mail to This e-mail address is being protected from spam bots, you need JavaScript enabled to view it

Canada encourages its citizens with multiple nationalities to use their Canadian passport when travelling abroad, especially when entering the country of their second citizenship.

Using your Canadian passport may provide the basis under which Canada can provide you with consular assistance if you run into difficulties. That may mean obtaining a visa, if that is required for entry by Canadian citizens, and always presenting yourself as a Canadian when dealing with local authorities.
