can you entry back to canada with TRV and OWP?
Technically, there shouldn't be any issues as long as your TRV is valid and you're leaving for a short period of time (couple of weeks max, I think). People on this forum say that usually CBSA officers let people in if they show their visa and OWP and let them know about their PR app.I have the same question!!
However, there's always a small chance they can be denied entry, you can never be certain of anything with CBSA. So my guess is if the trip can be postponed it's better to do it than to risk being denied and having to re-apply for PR.
This is what CIC website says:
