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.
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.
