Well two things: 1. Canadian household size is decreasing as more people are staying single, and people are living longer and becoming widowed. So even if population was completely flat Canada would need more homes over time. 2. Of course Canada has always had immigration and the population has thus always been increasing regardless of the birth rate. This is not a remarkable issue and easily accommodated by building more housing, but the severe systemic barriers to creating housing has made it more scarce and expensive than it should be. This was already the case in the major cities all the way back to the mid 2010s and the last government. The dominant problem here is bad housing policy dating back to the 1990s, not a sudden increase in immigration numbers in the last two years.
