Simple solution: limit housing to land that can't be farmed.

Problems with that plan: way higher development costs, higher food distribution costs, as well as more environmental impacts.

Quite frankly, there is no good solution. But it would be beneficial to convince people to move out of the bread basket of Ontario, to places like Thunder Bay, or the maritime provinces.

The draw, of course, is business wants to be in a big urban center, so people move there to have higher paying jobs. And be around other people. But, more affordable housing is already available in the areas I mentioned, and jobs can pay close to the same.
