The root cause of the problem was unwarranted loans.
We did not have that problem because of tight fiscal regulations in the banking sector.
It makes sense - better regulation keeps us safe.
It was a combination of past solid foundational practices - in infrastructure, and banking policies.
However, we can't get too cocky - as many banking policies were experiencing chinks in that armour and eventually would have gone down the tubes with the U.S., but not at the same rate - DUE to the rigid criteria in place decades before. It was when we started buying and cross buying financial subsidies etc that things started careening more.
We were fortunate due to the solid background/foundation of the past practices of Bank of Canada and the big 5. Many complain about our Banking system and criteria, but it did save us.
However, we can't brag that it was staying grounded during that time 2000-2010 (adding years makes it realistic), for subprime loans and flex lending became the norm ~ as did over lending. When Bank of Canada decided to set is prime rate below 1 that is a danger zone. And in a way created a "false sense of stability" to counterbalance real over lending and subprime rates. Private mortgage companies en mass were virtually unheard of in Canada as was the concept of any competition with the Big 5.
The rest, well...there is much on the surface, but like an iceberg, so much underneath, we still don't know...the whole story of financial breakdown or incompetencies during that time.....we "caught our selves in the nick of time...
We do know, on both sides of the border the plebeians always suffer the most.
