The CoPR just means that her PR has been approved. She now needs to 'land' as a PR and after she lands she will get the PR mailed to her (timing available at http://www.cic.gc.ca/english/information/times/perm-card.asp
To land before her CoPR expires, you can indeed make an appointment (as they suggested - beware it can take time for an available appointment so make sure they are aware of the expiration date). Alternatively, if you are close to the border, you can exit and re-enter Canada (e.g., drive to the US and head back to Canada) or possibly land at an international airport near you (there's conflicting info on this so it may depend on the airport - call to check first).
When she lands, make sure she processes her B4/B4A for any items she may have temporarily imported with her work permit so she can keep them in Canada duty free. If she has any goods she may have left abroad, she should list them also as goods to follow to be able to import them in the future duty free (with photos of jewelry, serial and model number of electronics, and VINs for vehicles).
Thanks to the helpful people on this forum my wife who is waiting on her PR to Canada has finally received a Confirmation of Permanent Residence letter!
However we are confused why we even received this letter. We assumed that when we sent her passport away it would be sent back with PR card and not just a letter stating she has been approved but no actual PR card. She is currently residing in Canada on a work permit and had a multiple entry visa which they have now annulled and issued her a new single entry Visa that is valid only for 5 weeks.
It states in the letter that if you are already living in Canada to call the 1-888 number to make appointment (good luck getting through). We will be trying that this week however can anyone advise on the process going forward? It it just a matter of one last appointment to actually sign something and pick up a card or will they make her jump through some more hurdles?
