Who was Jim, according to the passage?

Canada weathered the financial crisis well. No bank needed to be rescued; the World Economic Forum anointed Canada’s banking system the soundest in the world. Mark Carney was exported to the Bank of England in large part because of his work at the Bank of Canada. Stephen Harper, the prime minister, took to describing Jim, who died on April 10th just weeks after leaving the cabinet, as "the best finance minister on the planet". The government was lucky that steps had been taken to strengthen the banking system after a series of failures in the 1980s, he says; lucky that a previous Liberal government had eliminated the deficit; and lucky that resource-producing western provinces could take up the slack when the manufacturing heart land slowed dramatically. "There is a risk that if we think we’ve done really well because of our institutions and some type of Canadian exceptionalism, we might become complacent," says Mr. Di Matteo. Mr. Harper’s Conservative government has recognized some weaknesses. Despite the plaudits for its banks, Canada still has a "too big to fail" problem. Six lenders dominate a system with financial assets worth five times GDP. The federal banking regulator tightened up the banks’ capital requirements and supervision in March 2013. The body that would have to resolve a bank failure has been given more powers. In the past two years Canada has reached agreement in principle with the European Union on one free trade deal, signed another with South Korea and won admission to the group of 12 countries negotiating the Trans-Pacific Partnership. To diversify energy trade — almost all its oil exports currently head south — the prime minister has also thrown his weight behind a proposed pipeline that would redirect Alberta’s crude to Asia. But all this will take time. And Mr. Harper can no longer boast that Canada, smallest of the G7 economies, is leading the pack. The IMF projects growth will be 2. 3% this year, behind the United States and Britain.
