What the research suggested was not a correlation but a causation between investment in new co-op and non-profit housing supply and an increase in productivity levels. The recommendation is to at least double the supply of community and co-operative housing in Canada to restore a level of affordability and catch up with OECD comparators.
It's not just construction that supports productivity. It's at the household level. It's the effect of having an affordable and safe place to call home that's connected to community. Once you have the economic relief of having an affordable place to call home, it induces economic behaviours that support greater productivity outcomes. That's what the research demonstrates.
