Hmmm I certainly like to look at numbers/stats on the internet - also tend to link them here.
But to be fair, I do tend to assume the information is correct when listed from a major news outlet/Stats Canada/etc. But for all I know the information could be wrong - it does end up being a reputation thing.
Which is why the long term overestimation of US housing numbers was so surprising to me (and why I posted.) A national association of realtors would be an organization that one should be able to rely on for accurate numbers on things like housing sales for heaven's sake.
EDIT: I understand the need for revisions (like jobs numbers in the following quarter for example.) But to be off for years seems a bit hard to believe. That being said, we don't know the magnitude yet of that particular example yet.
