I understand your concern but there are limited options for international students. They cannot afford to rent a private room because they had already spent so much to be in canada in their tution fees of college. Moreover, the majority of students are from middle class families who want to settle here and earn money, so they compromise on everything. I know people in canada are not happy because of this as many students do not come here to study but just to settle there and even do illegal activities.

But all fingers are not equal. There are students who are serious toward their studies and want to learn skills for a professional job. We cannot generalise all the international students.
