I found this recent article
Ocotber 3, 2018 -- Toronto Real Estate Board President announced that Greater Toronto Area REALTORS® reported 6,455 sales through TREB's MLS® System in September 2018 – up 1.9 per cent compared to September 2017. The average selling price for September 2018 sales was up by 2.9 per cent over the same period to $796,786. The MLS® HPI composite benchmark price was up by two per cent year-over-year.
New listings entered into TREB's MLS® System in September 2018 amounted to 15,920 – down by 3.1 per cent compared to September 2017. With sales up year-over-year and new listings down, market conditions became tighter. Many buyers may have found it more difficult to find a home meeting their needs.
So my thoughts are that..
The lower supply and higher demand , with low interest rates for now will continue to drive prices up in the GTA.
Interest rates will have to increase a fair bit to see prices drop . Prices drop when there is more supply than demand
and homes sit on the market too long then you start to see more price reductions . The higher end homes take a bigger hit
but look at the condo market still booming and the rental market is insane in the GTA another indication of short affordable supply.
