This is, once again, apropos of nothing in particular. I just happened to come across it:

Household debt wasn’t the driver of the financial collapse in the United States, but it certainly played a role. And since the Great Recession, households have delevered considerably, from 100 percent to about 80 percent.
But in Canada, leverage went up during the recession and has kept going up ever since. They’re now above the highest point of the US housing bubble. Is this a problem?
