Some incorrect advice here. You are in breach of the residency obligation, so that means they can start the process of revoking your PR at the border. Whether or not they will is a different question, but as I have posted in another thread - people with valid PR cards do get reported for failing to meet RO, and they do lose appeals as well.
That said, it is possible, perhaps even likely, that you will be admitted into the country with only a warning, or not even questioned at all.
But it isn't a good idea to then leave again. If you are able to enter without being reported, common advice in the forum is to stay in Canada without leaving until you meet the RO again. This is because you don't want to take chances twice, and it's even more important if they do issue you a verbal warning on your first entry, because in that case it is likely they would have left a note in your file - which means almost guaranteed secondary inspection you travel the next time and a high chance you will get reported that time.
What is true is that as long as you are a PR (which you will be even if reported, because you get a time window during which a potential removal order is not enforceable yet), you will be admitted into the country.
Best advice in your situation, assuming you truly want to move to Canada: travel here as soon as you can, and stay here until you meet the RO. The longer you wait, and the closer you are to the expiry date of your PR card, the higher the chances of getting reported.
