Making the municipalities.... The federal government can do so much, but I think financial encouragements, or other types, normally move things. I think putting limits on the time it takes from a building permit being submitted to being approved would be the easiest thing to start with; start there.
If there are different rules and regulations from one municipality to another, provincial or otherwise, whether they're following the Ontario building code, the Manitoba one or the national one, so be it, but put a time limit on it. What should it be? It doesn't matter what it is, but if you can actually make that time limit a real thing, then people can work with that. They can budget for that.
