Maple News reports on a major shift in Canada’s approach to citizenship by descent. The December 15, 2025 amendments to the Citizenship Act—collectively known as Bill C-3—expand the path to Canadian citizenship for descendants of Canadian citizens. Canada continues to practice jus soli, or birthright citizenship, for most people born on Canadian soil, with only narrow exceptions. The new law adds a generation-spanning avenue for those who can prove an unbroken line to a Canadian citizen.
Under Bill C-3, the previous first-generation limit for transmission of citizenship by descent has been removed for anyone born before December 15, 2025. As long as there is an uninterrupted line of Canadian citizenship back to an eligible ancestor, descendants may qualify, regardless of where the intervening generations were born. In practical terms, a grandchild or even more distant descendant could become Canadian if they can establish the lineage.
A key caveat applies to births abroad on or after December 15, 2025. If the Canadian parent was also born abroad, they must show 1,095 days of physical presence in Canada before the birth, unless an exception applies. This creates a notable distinction between older cases and newer ones, where the presence requirement may come into play.
Canada has long practiced birthright citizenship, granting citizenship at birth to most people born on Canadian soil. When combined with Bill C-3, the policy could bring a Canadian connection to millions of families who previously had only an ancestral link—often without any active application on the part of the ancestor. Maple News notes that the change could influence family planning, sponsorship decisions, and long-term residency considerations for descendants pursuing Canada-based opportunities.
An illustrative example helps clarify the path: Sheila Morgan was born in Halifax in 1948 and left for the United States as an infant. Her granddaughter, Samantha, born in 2001 in Massachusetts, could now qualify for Canadian citizenship by descent, provided the chain back to Sheila’s Canadian-born grandmother can be established. Samantha would need to gather birth, marriage, and other relevant records to prove the lineage and then apply for a citizenship certificate before pursuing a Canadian passport.
What should you do if you suspect you qualify? Begin with your oldest living relative to map the family tree—ask who left Canada, when, and why, and collect details such as birthplaces and dates. Then assemble the supporting documents: birth, marriage, and death certificates for each generation in the chain, plus your own identity documents. Provincial vital statistics offices and archives are usually the best sources for historical records. Because processing times can be lengthy, starting early is wise. For complex cases—such as pre-1947 ancestors or surname changes—consider consulting a citizenship lawyer to navigate the lineage and documentation requirements.
For context, ancestors born in Canada before 1947 were generally British subjects at birth. In many cases, they could pass citizenship by descent once the Citizenship Act took effect. Still, every generation in the chain must be proven, not just the original ancestor. Maple News will continue to monitor how these rules play out for families pursuing citizenship through descent and what it means for Canada’s immigrant communities.
