There is a core housing need in the low-income sphere at 80% of the market rate, which is what CMHC refers to as “affordable”. It goes even further than that, and my term of “deeply affordable” refers to the amount that ODSP permits for rent. Just speaking of Ontario, but other provinces are similar, it's $497 per month per person.
If we don't intentionally build to that with appropriate targets in place, it won't be built. I would suggest to you that 10%, or in this case 10,000 of the 100,000 units being built, would be at the deeply affordable rate, at the ODSP rate, to allow access to those in greatest need. This would include the vast majority of those with intellectual and developmental disabilities, 90% of which live below the poverty line.
