Of course Wente is going to advocate for the anti-progressive viewpoint. She always does. What she doesn't appear to be aware of is that Toronto is surrounded by some of the best farmland in Canada. You can't eat houses, so let's not build on the farmland with urban sprawl.  

The solution to lack of supply of single family houses is if a strong municipal government creates a fair and equitable rental market that allows people to have a roof over their heads at regulated prices.  Empower municipal decision makers to create a rental market that can work for families. There are more than enough rental units in the city to cover the people living here.  If a family really must own a single family house in TO, let them buy it at these grossly overinflated prices. Otherwise, they should rent.
