Canada updates rules for citizenship by descent

Canada has clarified that citizenship by descent can only be passed through a direct parent‑child line. A child born abroad is eligible only if a parent was a Canadian citizen at the time of the child's birth, and each ancestor in the chain must have held Canadian citizenship when the next generation was born. The clarification excludes relatives such as aunts, uncles, cousins or other non‑direct ancestors.

The updated guidance notes that a parent who acquires Canadian citizenship after a child’s birth cannot transmit citizenship to that child. Marriage to a Canadian citizen does not automatically confer citizenship, and adoption follows a separate legal process. The changes, prompted by legal challenges to earlier restrictions, may allow some people previously deemed ineligible to be recognized as Canadian citizens from birth rather than receiving status only after an application.

Applicants are advised to trace the oldest direct Canadian ancestor and verify the citizenship status of each generation to determine eligibility.
