Yes, I understand that this isn't strictly true.
I guess a more accurate way to put it is that there is almost no one working in banking or any mortgages currently written where a major correction has happened. Canada wasn't whacked in 2008 nearly as bad as the US, and the early 1990s property corrections were much more regionally focused (Toronto got the worst of it), in Edmonton, 1989 and 1990 prices increased more than 20%. Basically there is no one with first hand experience in managing an upside-down housing portfolio.
Basically, for most property markets in Canada, plowing your money into property has been a historically better bet than the TSX.
