When to Change
Many new citizens change their name after receiving citizenship. It's easier to do it around the same time. You can change first name, last name, or both.
How to Change
File with your provincial Superior Court. Bring: citizenship certificate, ID, passport, fee ($150-300 depending on province). Court approves within weeks. Get certified copy.
Timeline
During IRCC processing: Submit name change request to court separately. After citizenship: Use new name for passport and other documents. Both can happen in parallel.
