Forget the opinions of foreign economists... especially when they're in countries who may have even more thorough tenant laws than we have. It's not an apples-to-apples comparison.
Even still, rent control is important. Renters need to have stability in their month-to-month payments, and there doesn't need to be an easy way to force people out of their homes (e.g., jacking up rent 200%).
Contracts should be long enough to offer stability. Fix the laws then.
Toronto issue is the public transport is terrible. Needs more rail to high density hubs around the city. But the real issue is the ridiculous immigration levels 20 percent of Canada is Immigrants. Of course all that's going to happen is it will keep houses increasing in prices and keep wages down.
Good for businesses and land owners bad for the everyday Canadian.
