Six months after the targets are set, Minister Kahlon says the province will evaluate progress and step in if municipalities are not demonstrating real progress. […] If needed, the provincial government may then begin approving important housing projects and revising zoning rules.

This is huge. A lot of the resistance to the necessary solutions come from NIMBYs who hold out-sized sway in municipal politics on account of the very low turnout in those elections. However, cities are ultimately entirely subject to the province so if you have a government willing to step in and make things happen, they can overrule a lot of that opposition.
