If your marital status changed (you got married) after your AOR but before your PR application is finalized:
- Declare it as soon as possible — don't wait until later in the process. A change in marital status after submission is exactly the kind of update IRCC expects to be reported promptly rather than left until it's convenient.
- Raise a webform with the relevant proof attached (marriage certificate and any other supporting documents) as the standard channel for reporting this kind of change.
- Understand why this matters even if you're not adding your spouse now: this declaration gets cross-checked later if you sponsor your spouse for PR — an undeclared marital status change discovered at that point can create bigger complications than declaring it upfront.
There's no benefit to delaying this disclosure, and doing it early keeps your file consistent for any future spousal sponsorship application.
