Born in Canada, Moved to US as Child: Am I Still Canadian?

If you were born in Canada but raised in the United States, you are almost certainly still a Canadian citizen. You didn't lose that citizenship by leaving as a child, and in most cases, your parents couldn't have given it up on your behalf. Your real challenge isn't eligibility—it's proving what you already are.

This is a fundamentally different situation from citizenship by descent. You acquired citizenship at birth on Canadian soil, not through a parent. That distinction matters both legally and practically.

Birthright Citizenship in Canada

Canada grants citizenship to anyone born on Canadian soil, with very narrow exceptions (children of foreign diplomats or enemy forces in wartime). This is called jus soli—the right of the soil.

It doesn't matter if:

• Your parents weren't Canadian citizens
• You left Canada as an infant
• You've lived your entire conscious life in the United States
• You've never had a Canadian passport
• Your parents became US citizens and you derived US citizenship through them

If you were born in Canada, you were a Canadian citizen the moment you were born. That status is permanent unless you formally renounced it as an adult (age 18+) or fell under one of the narrow historical exceptions below.

Historical Exceptions That Could Have Stripped Citizenship

There are two narrow categories of people born in Canada who may have lost citizenship:

1. Born Before 1947

Canada didn't have its own citizenship law until January 1, 1947. Before that, Canadians were British subjects. If you were born before 1947, your status depends on the complex interplay of British nationality law and whether you took steps to naturalize elsewhere. This is rare—most people in this category are no longer living or weren't raised in the US as children.

2. Retention Rules (Born 1947–April 16, 1981)

If you were born in Canada between February 15, 1977 and April 16, 1981 and one of your parents was a foreign diplomat at the time, you may not have acquired Canadian citizenship at birth. This is extremely rare.

If you were born in Canada and acquired citizenship in another country as a minor (through your parents' naturalization), you did not lose your Canadian citizenship. Canada eliminated those old "dual citizenship prohibition" rules decades ago.

Your Parents' US Naturalization Did Not Strip Your Canadian Citizenship

This is the most common fear. Many people born in Canada moved to the US as children, and their parents later naturalized as US citizens. When a child under 18 derives US citizenship through a parent's naturalization, some people assume the Canadian citizenship was automatically lost.

It was not.

Canada does not recognize foreign naturalization of a minor as grounds for loss of citizenship. You remained Canadian. You simply became a dual citizen.

The United States allows dual citizenship. Canada allows dual citizenship. You are both, and both countries are fine with it.

How to Prove Your Canadian Citizenship

Because you were born in Canada, your proof is straightforward:

Step 1: Get your Canadian birth certificate

Order a long-form birth certificate from the vital statistics office of the province or territory where you were born. If you were born in Quebec, see our Quebec-specific guide.

This document proves you were born on Canadian soil. It is the foundational proof of your citizenship.

Step 2: Apply for a citizenship certificate (optional but recommended)

The citizenship certificate (form CIT 0001) is the official government document that states you are a Canadian citizen. While your birth certificate proves you were born in Canada, the citizenship certificate is issued by Immigration, Refugees and Citizenship Canada (IRCC) and is often required for certain applications (sponsoring family, some employment contexts, or complex passport renewals).

The application fee is $75 CAD. Processing time is currently 9–12 months. See our step-by-step guide to form CIT 0001.

You'll need:

• Your Canadian birth certificate (long-form)
• Photo ID
• Two citizenship photos
• Any prior Canadian passport or citizenship certificate (if you ever had one)

Step 3: Apply for a Canadian passport

Once you have your birth certificate (and optionally your citizenship certificate), you can apply for a Canadian passport. If you've never had one, the passport office may ask for additional identity documents or a citizenship certificate depending on your situation.

See our guide on proof of citizenship vs. passport to understand which document you need and when.

What This Means for Your US-Born Children

Here's where Bill C-3 becomes directly relevant to you.

Because you are a Canadian citizen (by birth in Canada), your children born outside Canada are Canadian citizens by descent—no application or registration before age 18 was required under the old law, and still isn't under the new law.

But there's a critical difference depending on when your child was born:

Children Born Before December 15, 2025

If your US-born child was born before December 15, 2025, they are Canadian citizens under the rules in place at the time—even if they have never been registered. They can apply for a citizenship certificate at any time.

Under the old "first-generation limit" (in place 2009–2025), your US-born grandchildren would not have been Canadian citizens, because citizenship by descent was capped at one generation born abroad.

But Bill C-3 removed that limit retroactively. Now, your US-born grandchildren (if they exist) are also Canadian citizens, as long as your child (their parent) meets the substantial connection test if the grandchild was born after December 15, 2025.

See our grandparent pathway guide and great-grandparent guide for details on multi-generational descent.

Children Born On or After December 15, 2025

If your child is born outside Canada on or after December 15, 2025, they are only a Canadian citizen if you (the Canadian-citizen parent) meet the substantial connection test: 1,095 days of physical presence in Canada at any point before the child's birth.

If you left Canada as a young child and never returned, you may not meet this test. In that case, your child would not automatically be a Canadian citizen at birth.

See our full breakdown of the substantial connection test under Bill C-3.

You Don't Need to "Reactivate" Anything

You are not "reclaiming" your citizenship. You are not "reactivating" it. You are simply obtaining proof of a status you've held continuously since birth.

If anyone tells you that you lost your citizenship by moving to the US or by not maintaining ties to Canada, they are wrong. If you were born in Canada and did not formally renounce your citizenship as an adult, you are still Canadian.

Dual Citizenship and US Taxes

As a dual US-Canadian citizen, you are subject to US worldwide income tax reporting regardless of where you live. Becoming a Canadian citizen (or confirming that you already are one) does not change your US tax obligations.

Most dual citizens do not owe double tax thanks to the US-Canada tax treaty, but US reporting requirements (like FBAR and FATCA) still apply.

See our detailed guide on dual US-Canadian citizenship and taxes.

What If You Never Had Documentation?

Some people born in Canada to US parents were issued a US Consular Report of Birth Abroad or only ever held US documents. If that's you, you may never have been issued a Canadian birth certificate or passport—but that doesn't mean you weren't Canadian.

The absence of documentation does not negate your status. You'll need to reconstruct your proof:

• Request your Canadian birth certificate from the province/territory of birth
• Apply for a citizenship certificate if needed
• Bring certified copies of identity documents and any hospital records you have

If you run into complications or rejections, consult a Regulated Canadian Immigration Consultant (RCIC) or Canadian immigration lawyer. Arryv is not a law firm, and can't provide legal advice on complex status questions.

Next Steps

If you were born in Canada and moved to the US as a child, here's what to do:

1. Order your long-form Canadian birth certificate from the province/territory of birth
2. Decide whether you need a citizenship certificate (recommended if you'll sponsor family or want official status confirmation)
3. Apply for a Canadian passport if you plan to travel or live in Canada
4. Determine whether your US-born children are Canadian citizens under Bill C-3
5. If your children are eligible, apply for their citizenship certificates using form CIT 0001
