Thanks to major changes to Canada’s citizenship laws that took effect on December 15, 2025, some people can now qualify for Canadian citizenship through a great-grandparent, even if they, their parents, and their grandparents were all born outside Canada. This is one of the biggest expansions of Canadian citizenship-by-descent rules in decades.
📜 What Changed?
Before December 2025, Canada generally applied a first-generation limit (FGL) on citizenship by descent. This meant that Canadian citizens born abroad usually could not pass citizenship to their children born abroad.
The new law, known as Bill C-3, removed that restriction for many people born before December 15, 2025, and restored citizenship rights to millions of descendants of Canadians.
👨👩👧👦 How Citizenship Can Flow Through a Great-Grandparent
A simplified example:
Generation 1
Your great-grandparent:
- Born in Canada or naturalized as a Canadian citizen
Generation 2
Your grandparent:
- Born outside Canada
- May be recognized as a Canadian citizen by descent
Generation 3
Your parent:
- Born outside Canada
- May also be recognized as a Canadian citizen
Generation 4
You:
- Born outside Canada
- May now qualify as a Canadian citizen by descent
Under Bill C-3, citizenship can now be recognized through multiple generations if you can prove the family lineage connecting you to the original Canadian ancestor.
✅ You May Already Be a Citizen
One of the most important things to understand:
👉 If you qualify under the new law, you generally do not apply to become a Canadian citizen.
Instead, you may already be considered a citizen by operation of law and simply need to apply for a Proof of Canadian Citizenship Certificate to document your status.
📋 Documents You Will Likely Need
To prove eligibility, applicants often need:
- Their own birth certificate
- Parent’s birth certificate
- Grandparent’s birth certificate
- Great-grandparent’s Canadian birth certificate or citizenship record
- Marriage certificates (if names changed)
- Adoption records (if applicable)
Every generation in the family chain must usually be documented. Missing records are one of the biggest causes of delays.
⚠ Important Conditions
Eligibility is not based solely on having a Canadian great-grandparent.
IRCC may examine:
- Whether the ancestor was actually a Canadian citizen
- Historical citizenship laws in effect at the time
- Family lineage documentation
- Whether citizenship would have passed through each generation
Each case can be different depending on dates of birth, citizenship status, and family history.
🗓 Rules for People Born After December 15, 2025
The new law treats future generations differently.
If a child is born abroad after December 15, 2025, and the Canadian parent was also born abroad, the parent must generally prove at least 1,095 days (3 years) of physical presence in Canada before the child’s birth or adoption for citizenship to automatically pass on.
⏳ Processing Times
Due to a surge in applications after the law change, proof-of-citizenship applications are taking significantly longer than before.
Many citizenship-by-descent applications are currently experiencing processing times of approximately 9–12 months or longer, depending on complexity and document requirements.
🎯 Who Should Check Their Eligibility?
You may want to investigate your status if:
✔ Your parent, grandparent, or great-grandparent was born in Canada
✔ Your ancestor became a naturalized Canadian citizen
✔ You were previously told you were ineligible because of the first-generation limit
✔ You have Canadian ancestry but never applied for citizenship documentation
Many people who were previously excluded may now qualify under the updated law.
📌 Final Thoughts
Canada’s 2025 citizenship reforms have opened the door for many descendants of Canadians around the world. In some cases, a Canadian great-grandparent can now create a pathway to citizenship that was previously impossible under older rules. The key is proving the complete family connection and confirming that citizenship legally passed through each generation.
