I don't recommend travelling after your landing interview until you receive the PR card, especially if you are out of status. When they invite you for a landing interview, they ask you if you have any travel plans, if you say yes, they reschedule the interview till after you come back, so that you are in the country until you get your PR card.
If you are out of the country and don't have your PR card, then you have to apply for a PRTD from the country you are visiting, but often times, that requires filling in forms and submitting to the embassy of that country, and it can take from a few weeks to a month or so to get a PRTD. It just becomes a big hassle.
BUT this is only because the airline will not let you travel to Canada without a valid PR card or a permit etc. They don't accept the COPR etc. That's the real challenge. IF somehow you can convince the airline to let you on the flight, then when you land in Canada, the CBSA at the airport will let you in on a COPR. The port of entry rules that CBSA uses to determine if you can be let in can be found here in detail:

So the real challenge is about taking the risk. When was your landing interview, and when is your travel date? I would suggest you wait for the PR card.
Another way is if you know someone here who can check your mail and then courier your PR card to you directly in the other country, however if this method is legal is of question, because courier mail is checked too, and normally sending ID documents like passport or ID cards are often checked by customs officials to ensure no fake ids and passports are illegally being smuggled etc.
