Hi, I got Canada PR in May 2019 and it is valid until May 2024. I am still in US and planning to move to Canada this year or early next year. But if I am unable to live in Canada for 2 years before my PR expires, how can I apply to renew my PR with an exception reason? e.g. My move to Canada could be delayed due to ongoing pandemic - Covid. If I give this as a reason, can I get my PR renewed?
