Status of changes to the first-generation limit on citizenship by descent Updated December 15, 2025
On December 15, 2025, the Government of Canada passed Bill C-3 to change the first-generation limit on citizenship by descent.
The Ontario Superior Court of Justice ruled in December 2023 that the limit was unconstitutional for many people. In March 2025, we introduced an interim measure to support those affected.
We will now process all applications submitted under the interim measure using the new rules.
