This article claims to take its content from the report by the Bank of Canada, however there are great inaccuracies in this G&M article.
I'd ask that ANY readers who feel at risk, or doubt our lending policies in Canada, reach out to Mortgage Professional's Canada and inquire. You can find them here: https://www.mortgageproscan.ca/en/ 
You'll quickly find out just how prudent Broker Lenders are with their guidelines. 
Our lenders ARE regulated by OSFI.
Our lender's have investors OTHER than Banks.
Our policies DO ensure borrowers are protected and not given free money on the backs of CMHC or the OTHER 2 Insurers in Canada.

House prices and a housing correction are one thing.
Free money with no qualifying is another.
Broker lenders don't give away free money.
And Broker's are regulated by a Provincial body (like FSCO in Ontario)
Remind me again who regulates a bank employee?
