A friend of mine came to Canada on a Toursit visa from Australia 5 years ago to spend time with an eldery friend who lost her husband. She didnt intend to overstay but she was reluctant to leave her friend alone as she had no family. Anyway she would have left years ago but she is deadly afraid of being arrested at the airport. What is the procedure for leaving Canada from Toronto? Will she be arrested? Any information would be gratefully appreciated.
