The document is valid for one year I believe? But your PR status doesn’t expire just that you may need to get the PR card within a year may be... Please apply for PRTD for returning back to Canada.Hi, I received similar COPR letter on June 11 2020(CEC Inland) when I was in Canada.Immediately, I applied PR card as well. But, due to a personal emergency I came back to my home country. So, I don't have PR card in my hand to come back to Canada.
To come back Canada, is there any expiry date of COPR letter? What are the docs required to return ?
