That's basically what they're doing. They can't change zoning without changing the constitution, but they are giving out tens of billions of dollars conditional on appropriate zoning changes. BC has received lots of money that way, Toronto has bypassed the province to get theirs and Alberta has made it illegal for Calgary & Edmonton to access theirs.
