Hey There,
Usual processing time is around 60 days, but sometimes due to bureaucracy it can get delayed. If you want to leave Canada, then you could either come back via land with your CoPR and passport, or if abroad you would need to apply for a PRTD (like a visa for PR's) to go back.
If you want plan on staying in Canada, just be patient and try calling every few days. Until you get your PR card you CoPR with passport can be used for most government services.
Please note that PR's in Canada are not required to have a PR card by law, but having one makes like easier.
Hope this helps!
