My Spouse Is a Canadian Citizen by Descent — What Does That Mean for Me?

Key Takeaways

• Canadian citizenship by descent comes from a Canadian parent — it is not acquired through marriage, so it does not pass to a spouse automatically.
• A spouse who is now a citizen may be able to sponsor you for permanent residence, the path that can later lead to your own citizenship.
• Children you share may already be citizens by descent, depending on birth date and a physical-presence test.

When Canada's citizenship law changed on December 15, 2025, many people — a large share of them Americans — discovered they are Canadian citizens through their ancestry. If your spouse is one of them, they can apply for proof of Canadian citizenship, and once Immigration, Refugees and Citizenship Canada (IRCC) confirms it, they receive a citizenship certificate that unlocks a Canadian passport and the right to live, work and travel in Canada. The natural next question is: where does that leave you?

Can I become a citizen through my spouse?

No. Citizenship by descent is based on being born to or adopted by a Canadian parent; it is never acquired through marriage. So even though your spouse is now a citizen, that status does not extend to you automatically. What it does do is open options — and it may mean any children you share are citizens too.

The real benefit: sponsorship

Your spouse, as a Canadian citizen, may be able to sponsor you for permanent resident (PR) status if they meet the requirements. As a PR you gain most of what citizens have: the ability to live, work or study anywhere in Canada, access to most social benefits, and protection under Canadian law and the Charter of Rights and Freedoms. PRs must meet a residency obligation — generally at least 730 days of physical presence in Canada in every five-year period. Crucially, PR status also lets you apply for citizenship once you qualify, which generally requires:

• At least 1,095 days of physical presence in Canada in the five years before applying, including at least 730 days as a PR;
• Filing Canadian income taxes for at least three of those five years, if required to file;
• Depending on age, proving language ability, passing the citizenship test, and taking the oath.

Can every citizen by descent sponsor a spouse?

Not automatically. To sponsor a spouse, partner or child, a Canadian citizen generally must be at least 18, be living in Canada or show they plan to once you become a PR, and commit to supporting you financially. Several factors can disqualify a sponsor — including certain past violent convictions, defaulting on a previous sponsorship undertaking, incarceration, receiving social assistance for reasons other than disability, or an active removal order. If your spouse lives in or plans to settle in Quebec, they must also meet Quebec's own sponsorship rules.

What is required of the person being sponsored?

You and any family members on the application must pass background and security checks and a medical exam. Past criminal convictions can affect your admissibility, depending on the offence, how long ago it occurred, and whether you have since received a record suspension or rehabilitation. You do not need to be married to qualify: Canada also recognizes common-law partners (who have lived together in a marriage-like relationship for at least 12 consecutive months) and conjugal partners (in an exclusive, interdependent relationship for at least a year but unable to live together or marry due to legal, immigration, social, cultural or religious barriers).

What about our children?

Children you share with a spouse who is a citizen by descent may also be citizens through the same line. If your child was born outside Canada before December 15, 2025, Bill C-3 may have restored their citizenship — IRCC says that in most cases, people born abroad before that date to a Canadian parent are automatically citizens, including children of a parent who became Canadian through the change. For children born abroad on or after December 15, 2025, the rules differ: if your spouse was also born outside Canada, they generally must show at least 1,095 cumulative days of physical presence in Canada before the child's birth or adoption for citizenship to pass on, unless an exception applies. A child from a previous relationship with a non-Canadian would not become Canadian through your current spouse, though your spouse may still be able to sponsor that child for PR — generally if under 22, or older where the child has depended financially on a parent since before turning 22 because of a disability.

Next steps

A spouse who has just learned they may qualify cannot sponsor you right away: they first need acceptable proof of citizenship, such as a certificate. As of writing, IRCC's proof-of-citizenship processing time was listed at about 19 months, though this can change and run longer. To apply for the certificate, a newly recognized citizen should gather documents for every generation in the family line — birth, marriage or adoption records connecting them to their Canadian parent, grandparent or earlier ancestor, each from the original issuing authority such as a provincial vital-statistics office — then complete and submit the paper Application for a Citizenship Certificate (CIT 0001), along with any situation-specific forms, required photographs and identification.

What This Means for Applicants: If your spouse has become a citizen by descent, your own route runs through sponsorship, not marriage — and it starts only once they hold a certificate, which is currently the slow step at roughly 19 months. The most productive move now is to confirm your spouse's eligibility, begin assembling original-source documents for every generation, and map the certificate and any sponsorship together so the two stages don't stall each other.
