The difficulties they face in housing mainly come from extremely limited economic problems and credit problems, which are also closely related to the increasingly fierce rental market. In this predicament, they have to consider more factors in their rental choice. After graduation or employment, many young people will choose to be independent, leave their parents and live closer to their workplace because of their workplace. Limited income and financial resources make it difficult for them to choose to buy a house at the beginning of graduation, so most young people have to choose to rent a house. According to the official report given by the Toronto Real Estate Bureau, this group of young people occupies a large proportion in the rental market in Toronto and is the main source of demand in the supply-demand relationship in the rental market today.
