Overstayed in Canada. Going back to my country for good. What can I expect at the airport?

Hello,
My study permit had expired on August 1st, 2018 and I honeslty didn't want to leave so I overstayed but now I have decided to return to my home country and not come back.
What can I expect by the CBSA at the airport?
Thank you

Unlikely to have any interaction with CBSA on leaving the country, passport will be scanned at checkin and that should be it
