The thrust of it is that the federal government would withhold funding to municipalities unless they meet certain home-building targets.
Critics worry that this will accelerate suburban sprawl in order to meet quotas. There are some provisions regarding rental housing and transit infrastructure, but with unrealistic time/budgeting constraints.
I’ve said this before, but coming up with no ideas of your own except to crack your whip at other people until they do something is bad McDonald’s manager level of leadership. Housing is an issue country wide, expecting municipalities to each individually come up with solutions for you instead of developing a country wide strategy is going to lead to extremely uneven results at best. Most likely it’s going to be a disaster everywhere because municipalities don’t have the power to deal with root causes like land speculation the way the federal and provincial governments do.
I also would bet money that if municipalities start getting homes built in ways the Conservatives don’t like, like public housing, they will be punished for that as well.
