In order to renew your Permanent Resident Card Renewal, you must meet the residency requirement of two years out of five (730 days) of “residence” in Canada. There are four ways to meet the residency requirement:
1. be physically present in Canada
2. be accompanying a citizen who is a spouse, common-law partner or parent
3. be employed full-time by a “Canadian business” or public service, and required by it to travel
4. be accompanying a permanent resident who is employed by a “Canadian business” or public service, and required to travel
If you do not meet the residency requirement, you may still submit your renewal application with a request for humanitarian and compassionate considerations. You will need to provide a detailed explanation as to why you were forced to remain outside of Canada. It is up to the discretion of Citizenship and Immigration Canada to determine whether the Permanent Resident Card will be renewed.
