Why are private developers building social housing?

Three major private real estate developers are involved in building social housing in Montreal. This item asks why and arrives at some interesting answers: they’ve glutted the market but need to keep their teams working, they find the presence of the homeless is bad for business, and it may be a way to get hold of public funds, Quebec having basically given up on participating in providing housing at all.

Tax breaks for the developers, and how they may be using these projects to offset the requirement for affordable and social housing in other projects, are not mentioned.
