The mixed-income model is certainly something that helps create more cohesion in a community. It ensures that households that may face typically systemic barriers to social and economic participation have a conduit to inclusion by virtue of having neighbours they can rely on for some support.
Oftentimes what's also advantageous about this model is that housing co-operatives are often very well placed in neighbourhoods and in a community, so residents of a housing co-operative are not segregated in any form from the mainstream of community life. By virtue of the model being inclusive and well placed in a community, we tend to see better housing outcomes for Canadians.
