The reason I can't give you the number of dwellings is that it's not just a matter of building houses. Housing is complex, and affordability can be met certainly by building houses, which is very important, but there is also a need to think about how much people are paying for their housing and their income level. It's quite complex to land on an exact number. Just to give you a little sense of it, currently.... According to the 2016 census, 1.7 million Canadians were in core housing need, meaning that 1.7 million Canadian households were spending more than 30% of their income on house-related expenses.
The magnitude of the challenge is quite significant. CMHC used 2030 because that's aligned with the UN's SD goals. It's a bit of a moon shot aspiration for us, and we like to have that as our moon shot, because it really helps galvanize the organization to help serve Canadians better.
