Regulation has NOT stifled technical innovation in banking in Canada. It did, however, prevent the banks from getting in up to their necks in the CDO/CDS/real estate boondoggle. I think I like that.
The article laments that there are not thousands of banks like in the US. No thanks. How many of those banks went out of business in the last few years? No thanks. Having a small number of very well regulated, and actually fiscally conservative banks sounds to me like a fair trade for whatever it is having thousands of poorly regulated banks gets you that is so awesome its worth risking a major financial meltdown.
