In the USA, after they bailed banks by those they ripped off, than bailing those that got ripped off, the banks merged and grew to become even that much more bigger to fail. On the other hand, Canadian banks are so conservative that they won't risk to grow, unlike America banks who have folded in the past. 

I guess the worst thing is that Canadian banks see ongoing record profits as the people only run ongoing record debt, that fuels our financialized economy to the glee of banksters.  Then praised by those we elect to represent our best interests, whether they share our values or not. as the fastest growing industry. I still remember the so called record surplus from the oxymoron of a jobless recovery, now look.
