U.S. leads spike in applications for Canadian citizenship by descent
OTTAWA — Interest in Canadian citizenship by descent among citizens in a handful of countries — especially the United States — surged after the federal government passed a new law clarifying the rules.
C-3, which took effect on Dec. 15, 2025, allows someone born outside Canada to a Canadian parent who also was born outside Canada to file a citizenship claim — as long as the parent spent at least three years in Canada before their child’s birth or adoption.
The law was drafted and passed in response to a 2023 Ontario Superior Court order that found a law on citizenship by descent passed by Stephen Harper’s government was unconstitutional.
That Harper-era law said Canadians who were born abroad could only pass down their citizenship if their children were born in Canada.
