Reported bcz one month is less from two years ?:/
Once you've spent 36 months outside Canada within 5 years of becoming PR, you are in violation of the RO. This is because there would be no way to meet 2 years in Canada within 5 years from date of your PR landing.
And once in violation of the RO, CBSA can report you upon any entry to Canada and start process to revoke your PR status. As i said whether or not they decide to investigate your RO upon entry, is up to any individual CBSA officer you encounter.
