So can you compare cost of living between NYC and Toronto and does the difference in median account for COL difference ?

Would be interesting to hear some first hand experiences from people who lived in both or similarly comparable US/Canadian cities. I was under the impression that Chinese investment in Canadian real estate really destroyed the housign market. I feel like the growing popularity of investing in residential real estate is a global phenomena but some markets are more exposed to some effects than others so it's possible to get some intuition on what impacts it.
