The inheritance that isn’t money: What Canadian citizenship could mean for your American children and grandchildren

You’ve likely thought about what you’ll leave your children. The house. The savings. Maybe your father’s watch.

One item on the list is now more accessible to some Americans than ever before and may have the greatest impact on their children: Canadian citizenship by descent. If you can trace a direct lineage to a Canadian ancestor, you may be Canadian today, and your children may be Canadian too. That includes adult children, and often grandchildren.

Most families who claim this inheritance have no plans to move. They want options. A Canadian passport gives your children a second set of choices they can use or set aside.

Your children or grandchildren could take a working holiday in Ireland or Australia in their twenties. They could pay domestic tuition at a Canadian university. They could take a job anywhere in Canada without a work permit, with healthcare available if they settle there.

And they keep their U.S. citizenship throughout, with no prerequisite or obligation to move to Canada.

What Canadian citizenship gives your children over a lifetime

Canadian citizenship has no expiry date. Your children don’t have to use it this year or next. They can draw on it at different stages of their lives.

At university age, it cuts the tuition bill significantly. Canadian citizens pay domestic tuition at Canadian universities, even if they grew up in Ohio or Florida.

Take the University of Toronto as an example. In 2026-27, a domestic student from outside Ontario pays $7,610 CAD (about $5,440 USD) for first-year Arts & Science. An international student in the same program pays $66,110 CAD (about $47,270 USD). At this year’s rates, that gap adds up to more than $230,000 CAD (about $167,000 USD) over a four-year degree.

In their twenties, it lets them work abroad. Canada runs International Experience Canada (IEC), a set of youth mobility agreements with more than 35 countries and territories. These agreements let young Canadians work and travel abroad on special permits.

A Canadian aged 18 to 35 can spend up to three years in the United Kingdom, with two years plus a one-year extension. In Ireland, the limit is two years. Other partners include Australia, New Zealand, Japan, South Korea, France, Germany and Portugal. Each country sets its own age limits and residence rules. The UK and Ireland both require a valid Canadian passport. Ireland requires one valid for 30 months from the date of entry.

In their thirties and forties, it removes the paperwork. Your son can accept a job offer in Toronto without a work permit. Your daughter can move her family to Halifax without applying for permanent residence (PR), Canada’s status for immigrants who settle long-term. Neither faces a visa lottery, a points system or a renewal date.

If they settle, healthcare follows residency. Citizenship alone doesn’t come with a health card, because each province sets its own rules. In Ontario, a citizen qualifies for the Ontario Health Insurance Plan (OHIP) by making Ontario their primary home and staying there at least 153 days a year. Ontario has no waiting period, so coverage starts once they’re approved.

Through it all, they stay American. The U.S. and Canada both allow dual citizenship. Your children keep their U.S. passport and add a Canadian passport alongside it. Canada taxes people who live in Canada, not citizens who live elsewhere. A child who holds Canadian citizenship but lives in the U.S. owes no Canadian income tax just for being a citizen. U.S. citizens still file U.S. taxes wherever they live.

And they can pass it on. Like any heirloom, citizenship can move down another generation. That’s where the rules come in.

Who qualifies, and what you’re applying for

If you qualify, Canadian law already treats you as a citizen. The application gets you a proof of citizenship certificate, the document that confirms that status.

The core requirement is a family line. You need an unbroken line of descent, parent to child, back to an ancestor who was a Canadian citizen. That ancestor might be a parent, grandparent, or any relative in your direct line who was born in Canada or naturalized there. They never needed a Canadian passport, and they never needed to apply for proof themselves.

If you were born before December 15, 2025, the number of generations doesn’t matter. You won’t face a language test, a citizenship test or a residency requirement.

The proof comes from paperwork. Canada’s citizenship department asks for documents from the original issuing authority for every generation. That usually means birth certificates naming each parent, plus the ancestor’s Canadian birth or naturalization certificate. Family trees and genealogy printouts help you find those records. On their own, they won’t support an application.

Far more Americans qualify than apply. Many families have lost track of a Canadian grandparent, or an anglicized surname hides the link. In New England alone, roughly one in four residents may be eligible.

The rules for passing it down

Canada changed its citizenship by descent law when Bill C-3 took effect on December 15, 2025. The law set up two tracks, and the dividing line is a birth date.

Children born abroad on or after December 15, 2025 face a new test. If a Canadian parent was also born outside Canada, that parent must show they spent at least 1,095 days in Canada before the child’s birth or adoption. That’s three years in total. The days don’t need to be consecutive, and they can come from any stage of the parent’s life.

That rule shapes the choices your adult children make today. Say your daughter lives in Denver and plans to start a family in a few years. If she was born in the U.S., her future child won’t be Canadian at birth unless she meets the 1,095-day test first.

Applying for proof early doesn’t exempt anyone from the test. It gives your children time. A 28-year-old who confirms their status now can start building those days in Canada. They can also plan a birth in Canada, since children born on Canadian soil are citizens regardless of the test. CIC News has covered how new Canadian parents can work around the 1,095-day rule.

Children and grandchildren born before December 15, 2025 face no such test. They inherit citizenship through the same line of descent that makes you Canadian. There’s no limit on generations, as long as each person can trace an unbroken line back to a Canadian ancestor.

Each generation needs its own proof. Being Canadian by law and holding a document that proves it are two separate things. Your children can’t use your certificate. Each person files their own application for proof of citizenship. Canada’s citizenship department expects documents that link every generation back to the Canadian ancestor. A passport comes only after the proof certificate.

That sequence takes time. As of October 2026, Canada’s citizenship department lists a processing time of 34 months for a new proof of citizenship application. About 130,700 people are waiting in the queue. A 26-year-old who applies today could have a certificate by age 29. That leaves room to apply for a passport and plan a working holiday before IEC age limits close.

Families often start with one person’s research. The birth certificates and marriage records you gather for your own application can form the backbone of your children’s files. You can check whether your family line qualifies with CanadaVisa’s free citizenship by descent eligibility checker.

A watch or a house passes down once. Canadian citizenship can keep moving through your family for generations, if each generation knows the rules that keep it going.
