Well, we're not experts in housing policy, but I think the message is that policies that are focused on supply are going to help fix the situation.

It's really very much policies that are focused on supply, and that does require an unusual level of co-operation among the municipal, provincial and federal governments, because the instruments on supply are spread out across different levels of government.
