Average tax rate for Ontario on 40k income is around 13%. https://www.eytaxcalculators.com/en/2022-personal-tax-calculator.html
I did say $40,000 beyond the basic personal amount. Not $40,000 total.
If that person wants to move to an equivalent house with an equivalent valuation on the other side of town, they would need to come up with $200k to pay the tax bill or add that to their mortgage. That is very strong incentive to never move. That kills labour mobility. It also means that the high bidder for housing will be long holding duration owners like landlords.
That is true IF the idea fails to stifle price growth which is the point of the exercise.
If we return real estate to its more traditional average growth in line with inflation or just over..........then the massive capital gains are unlikely accrue.
