Housing shortage

Canada has a housing shortage.

Single adults outnumber single-person homes by more than 3 to 1. This leads to some people being stuck living with relatives or roommates they don't get along with, or even ex-partners. Of the single people who can afford to live alone, it's common to live alone in a multi-bedroom home; this leads to a shortage of housing for families as well.
