Yes, I'll add one quick comment.
One thing I like about the gas tax model is the certainty and predictability of the funding. I think that's really important, especially in something like development approvals, which you're in for the long game. That predictability of funding would be key.
In terms of what municipalities must do to access funding, in the first part of the question, I would suggest that it's reasonable to have some policy gateposts in place. There isn't much point in the federal government's putting funding into missing middle housing if municipal zoning bylaws do not permit missing middle housing. I think having those types of policy gateposts in place would be a reasonable expectation of municipal partners.
