You have very good chance not to be reported, as per the experience most people shared very much similar to your case, in my opinion you have 80% to 90% chance you will not be reported if you fly back by end of September/ October. Based on questioning at POE, you just have to be very humble, polite and apologetic in front of CBSA officer and promised to him that you are moving to Canada for ever with no intention of travelling back in next two - three years.
Nevertheless, if you have a bad day and encountered a tough CBSA officer, is your luck. As a plan "B" you can bring some doctors reports stating that due to relationship problems you were going through some physiological treatment and hence didn't manage to travel in time to Canada (I assumed this what you are saying in your post). During the appeal hearings yours Doctor's report may be help to you to gain some sympathies of the judge and may be decision come in your favor, other than that if you are reported and you appeal in one month you will have hearing in about 1 to 1/2 year, if you remain in Canada and able to secure some job than you would have your ties that might convince the Judge that you have potential to settle yourself and judge to let you go.
