In the Globe and Mail today, Bill Downe, CEO of the Bank of Montreal, throws his support behind Finance Minister Jim Flaherty’s push for a national securities regulator. Most people support the idea—getting rid of 13 regulators in favour of just one makes too much sense to ignore. But Flaherty has been largely out on his own arguing the case. He hasn’t had a chorus of big name business leaders backing him up against the increasingly defensive provinces. His movement has had very little momentum. But this is a big name for Flaherty to have on his side.
