As of this week, according to the latest MLS stats circulating on industry social media, there are now more than an astounding 32,000 active residential real estate listings in the GTA, not even counting never-lived-in units. This is the most in many years, perhaps ever, and has created the largest disparity the city has seen between supply and demand.

You can't call it a collapse, complain about all the supply you have, refuse to reduce prices, and rally to the praises of free-market capitalism. The market has spoken. You have overvalued your property. Now give us houses and take your loss.
