This is the email I sent. I sent separate emails.
"I currently live in Winnipeg. I received my confirmation of permanent residency in mail 2 weeks ago for my wife and myself and was wondering how I can validate my permanent residency since in person appointments have been canceled. The expiry date of my COPR is June 11, 2020 which is less than a month from now. Please kindly help me as to what the next step is. "
And then I included my name, application number, UCI, Phone number, date of birth, and address
Hope this helps.
