Approved permanent residence applications (COPR and PRV)
Permanent residence applicants who are in possession of a confirmation of permanent residence (COPR) and permanent resident visa (PRV) and inform us, by submitting a web form to IRCC, that they are
unable to travel within the validity of their documentation should be processed as follows:
- Valid COPR and PRV: In an effort to reduce the number of cancelled COPRs and PRVs, a note should be placed in the file explaining that the applicant is unable to travel, and the file should be brought forward to the expiration date of the COPR and PRV. If the applicant informs IRCC that they can travel prior to the COPR and PRV expiration, they are encouraged to use their existing COPR and PRV to land.
- Expired COPR and PRV: If the applicant informs IRCC via the web form that they were unable to travel after the expiration of their COPR and PRV, or if they were unable to travel prior to expiration, officers are to re-open the application, and it should be brought forward for review in 90 days.
Re-opened applications
Approved applications can be re-opened in GCMS by cancelling the COPR and PRV and removing the final decision.
When to review a re-opened application
Once the applicant informs IRCC via the web form that they are
able to travel, a re-opened application may be re-approved provided that the applicant and their family members, whether accompanying or not, have valid immigration medical examinations, criminal and security checks and passports.
If the 60-day waiting period elapses and the applicant
has not informed us that they are able to travel, a note should be placed in the application, and it should be brought forward for review for an additional 60 days.
