Canadian Citizenship by Descent: Bill C-3 Rules

A Door That Reopened for Families Born Abroad

For many years, Canadians born outside Canada could not pass their citizenship to children who were also born abroad. This rule was called the “first-generation limit,” and it left thousands of families with Canadian roots without citizenship. Since December 15, 2025, a new law called Bill C-3 has removed this limit, so many of these people are now Canadian citizens. If your parent, grandparent or great-grandparent was Canadian, you may already be a citizen without knowing it.

If You Were Born Before December 15, 2025

If you were born or adopted outside Canada before December 15, 2025, and the only thing that stopped you from being Canadian was the old first-generation limit, you are now recognised as a Canadian citizen. This happens automatically, and it counts back to the day you were born. You don’t need to apply to become a citizen, but you do need to apply for a citizenship certificate to prove it. This rule can also reach grandchildren and great-grandchildren, as long as the family line can be traced back to a Canadian citizen.

If Your Child Is Born After December 15, 2025

For children born or adopted abroad on or after December 15, 2025, there is a new condition. If the Canadian parent was also born or adopted outside Canada, that parent must show a “substantial connection” to Canada. This means the parent must have spent at least 1,095 days, or about three years in total, physically in Canada before the child’s birth or adoption. These days don’t need to be in a row, so shorter stays over many years can add up.

How to Apply for Proof of Citizenship

To get official proof, you apply to Immigration, Refugees and Citizenship Canada (IRCC) for a citizenship certificate. You’ll need your application form, your identity documents and evidence that links you to your Canadian parent, such as birth certificates and your parent’s proof of citizenship. Missing or unclear documents are the most common cause of delays, so prepare your family records carefully before you apply. Once you have your certificate, you can apply for a Canadian passport.

Start Gathering Your Documents Now

If you think you or your child could qualify, start collecting your documents early, even if you don’t plan to travel soon. Look for birth and marriage certificates for each generation, and your parent’s Canadian citizenship documents. Applications can take time, so having everything ready now can save you weeks or even months later. Always check the latest rules and processing times on the official IRCC website.
