Hi, I used to be an international student in Canada from 9/2019 to 4/2020. I have returned to my home country and won't enter Canada to study in the future (I have withdrawn from college in Canada). Recently, I receive emails from the college inform me that I need to file my income tax. While I was in Canada, I didn't work anywhere. I am in desperate need for a solution to this problem. Thank you for reading.
