IRCC updated their website for expired COPRs:
If you have an expired COPR, you won’t be able to travel to Canada until we reissue your documents. Normally, you’d have to reapply, but right now we’re making exceptions for people who couldn’t travel to Canada due to travel restrictions related to COVID-19.
We’ve already contacted most people with expired COPRs issued on or before March 18, 2020, to explain what to do. If we already sent you instructions to do a new medical or submit updated documents, follow them and wait for us to tell you what happens next. You don’t need to contact us again.
We’re also working to contact anyone else with expired COPRs, including those issued after March 18, 2020.
What happens next:
We’ll send you an email about your application.
If you answer the email and tell us you still want to come to Canada, we’ll tell you what to do next.
We may ask you for new medicals and/or updated information.
If you don’t respond, we’ll keep your file closed and you’ll have to reapply when you’re ready to come to Canada.
When we email you, we’ll ask you to tell us if your family situation has changed (for example, newborn, marriage, divorce) so we can update your application and ask you for any other documents we need. We may also need updated documents if the ones you previously submitted are no longer valid (police certificates, medical exams, etc.)
Do not do an up-front medical exam. If you need a new medical, we’ll send you new instruction forms to take with you to the doctor after you reply to our email. This will help avoid processing delays.
To avoid delays, we ask that you don’t contact us via our web form or through the processing office email. If you have already contacted us, please wait for our instructions.
We expect people with a COPR and permanent resident visa that are valid until October 1, 2021 or after to have enough time to come to Canada before their documents expire.
Travelling to Canada
You can travel to Canada once we confirm to you in writing that we
re-issued your documents and
sent you a reprinted COPR and (if you need one) a new visa sticker in your passport
If we reissue your COPR, we’ll send you the documents you need to travel
