Just to add further kelly b.'s comments:
The Bank of Canada's Board of Directors chose Mr. Macklem, who holds economics degrees from Queen's University and the University of Western Ontario, to replace outgoing Senior Deputy Paul Jenkins, who announced in October that he would retire when his current seven-year term expires in April.
Mr. Macklem, who first worked at the Bank of Canada for a year in 1984 before starting on his PhD studies at London, Ont.-based Western, will take up his new post July 1, the Bank of Canada said Friday.
That delay will allow Mr. Macklem, currently associate deputy minister of finance and Canada's Group of Seven deputy, to continue his role as Canada's lead negotiator at international talks aimed at avoiding a repeat of the financial crisis. Mr. Macklem is the co-chair of a group within the Group of 20 that is evaluating ways to overhaul financial regulations.
(Seems that most Bank of Canada Sr. Deputy/Governor have gone through the University of Western Ontario's Ecomonic Program. Must be one the pre-requisites ).
