How to Get Dual Citizenship in Canada: Residency, Tests, and Taxes

Canada allows dual citizenship, so you can become a Canadian citizen without giving up your current nationality. To get dual citizenship in Canada, you first obtain permanent resident (PR) status, live in Canada long enough to meet the physical presence requirement, satisfy language and tax-filing rules, pass a knowledge test, and take the Oath of Citizenship. The government fee is $649.75 CAD per adult, and whether your original citizenship survives depends on your home country’s laws, not Canada’s.¹

Check Your Home Country’s Rules First

Canada places no restrictions on holding multiple citizenships, but your country of origin might. Several countries, including China, India, Japan, and Nepal, either prohibit dual citizenship outright or require you to renounce your existing citizenship if you naturalize elsewhere. Others impose obligations like military service on citizens who acquire a second nationality. Losing your original citizenship without realizing it can create serious complications for property ownership, inheritance, and future travel, so confirm your home country’s position before you file anything with Canadian authorities.

You Need Permanent Residency First

You cannot apply for Canadian citizenship directly. Every applicant must already hold valid PR status in Canada before submitting a citizenship application.² If you have an unfulfilled removal order or outstanding conditions tied to your PR (such as a medical screening you never completed), you are not eligible. Confirm your PR status is still valid and has not lapsed before you start.

Getting PR is a separate process with its own timelines — Express Entry, Provincial Nominee Programs, family sponsorship, and refugee protection each have their own criteria and can take months or years. Citizenship planning begins the day you receive PR, because the clock for physical presence starts running from that point.

Eligibility Once You’re a Permanent Resident

The following requirements apply to adults aged 18 and older. Meeting every one of them before you submit is the best way to avoid delays.

Physical Presence

You must have been physically present in Canada for at least 1,095 days (three years) during the five years immediately before you sign your application.³ Of those days, at least 730 must have been spent as a permanent resident, so temporary-resident time alone cannot fulfill the requirement.²

Time in Canada as an authorized temporary resident or protected person before you became a PR counts as half a day each, up to a maximum credit of 365 days.³ IRCC provides an online Physical Presence Calculator, and using it beats doing the arithmetic yourself.⁴

Language Proficiency

If you are 18 to 54 on the day you sign your application, you must show adequate English or French. The minimum is Canadian Language Benchmarks (CLB) Level 4 in speaking and listening.⁵ You can prove this with an approved language test result, or a diploma or transcript showing you completed a secondary or post-secondary program taught in English or French. Applicants 55 and older are exempt.²

Tax Filing

You may need to have filed Canadian income taxes for at least three of the five years before your application.² The application asks whether you were required to file and whether you did. Notices of Assessment from the Canada Revenue Agency are your proof, so keep copies for every year in your eligibility window.

Criminal Background

You will need police clearance certificates from every country where you lived for six consecutive months or more since turning 18. The certificate from your current country of residence must have been issued within six months of your application.⁶ Canada isn’t on that list because IRCC runs its own domestic checks. Convictions for terrorism, treason, or war crimes committed while a permanent resident will block your application outright.⁷

Documents to Gather Before You Apply

Getting everything together before you open the application form saves real time. The core documents:

Two pieces of identification, including a Canadian PR card (valid or expired) and a second government-issued ID such as a provincial health card, plus the identity page of your passport or travel document from your country of origin.⁸
Language proof (applicants 18 to 54 only): an approved test result or an educational diploma or transcript in English or French.
The output from the IRCC Physical Presence Calculator, supported by travel records such as passport stamps and boarding passes.
Notices of Assessment from the CRA for each year you were required to file within your eligibility window.
Police clearance certificates from every country where you lived six consecutive months or more since age 18.
Photos: two identical printed photos for paper applications, or one digital photo for online, meeting IRCC’s format requirements.⁹

Documents not in English or French need a translation. If the translator is certified, the translation is enough on its own. If not, you also need a sworn affidavit from the translator confirming their fluency and the accuracy of the translation.⁸

Filing, Fees, Test, and Ceremony

Most applicants apply online through an IRCC account, which lets you upload documents directly and is the faster option.¹⁰ Families can submit together through one account. Paper filing is required in a few narrow cases, including when your presence calculation includes time as a Crown servant abroad, or when a representative is completing the application for you.

The total adult fee is $649.75 CAD: a $530 processing fee plus a $119.75 right-of-citizenship fee.¹ Budget separately for foreign police certificates, certified translations, and photos.

After IRCC confirms your eligibility, applicants aged 18 to 54 are scheduled for a citizenship knowledge test: 20 multiple-choice or true/false questions, 45 minutes, 15 correct to pass.¹¹ Questions cover Canadian history, geography, government, laws, symbols, and the rights and responsibilities of citizenship. The official study guide, “Discover Canada,” is free on the IRCC website. You get up to three attempts in a 30-day testing window; fail all three and you’re invited to a hearing with a citizenship official.¹² Applicants 55 and older skip the test.

Once approved, you attend a citizenship ceremony and recite the Oath of Citizenship, pledging allegiance to King Charles III, King of Canada, and committing to observe Canadian laws.¹³ You can recite it in English, French, or both. You receive your citizenship certificate at the end, and that’s what you’ll need when you apply for a Canadian passport.¹⁴

What Dual Citizenship Means Day to Day

Once you take the oath, you hold two citizenships. A few practical points follow from that.

Two Passports

As a dual Canadian citizen, you must carry a valid Canadian passport to enter Canada by air, even if your other country requires you to travel on its passport.¹⁵ Most dual citizens end up traveling with both. A special authorization can let you board a Canada-bound flight without a Canadian passport in limited situations, but it isn’t a reliable long-term plan.

Consular Protection Shrinks in Your Other Country

If you travel to your other country of citizenship, Canada’s ability to help you in an emergency drops sharply. Local authorities may refuse to let Canadian consular officials assist you, and they are within their legal rights to do so.¹⁵ In a third country that recognizes both nationalities, you would generally have access to either country’s consulate.

Tax Obligations

Canada taxes its residents on worldwide income, regardless of where it was earned.¹⁶ If your other country also taxes citizens on global income (the United States being the most notable example), you can face double-taxation exposure. Canada has tax treaties with dozens of countries to reduce or eliminate the overlap, but working through them usually calls for a tax professional who handles cross-border cases. Don’t assume the treaties do the work automatically.
