From the article: "Which is fine, I guess, provided Canada never experiences an economic crisis like the one we had in the last decade. And the decade before that. And the decade before that."
===============

Looking back to economic conditions post-WWII we get the following approximate timeframes for the start of relatively notable recessions:

1949
Mid 1950's
1960/61
1973
1980/81
1990/91
1999/2000
2008/09

After a few shorter periods the world seems to have settled in to a pretty consistent 9 to 10 year span from the start of one recession to the start of the next recession.

It has been 8 and a half years since the last recession started.
