why canada's housing market didn't crash, page-57

"KEEN was wrong. As simple as that. Now he is blaming the stmiulus, why didnt he changed his forecast after the govenrment introduced the stimulus?
he is still advocating that the property will crash 40%, does that mean property will have to fall more than 50% now that the prices went up 20%."

Yes he was. I don't see anyone on here arguing differently. Yes he didn't account for the stimulus. Is he allowed to change his prediction after the result is known?
There were two predictions made. One I believe is still in play.
