After months of speculation about his future, former Bank of Canada governor Mark Carney launched his campaign to replace Justin Trudeau as Liberal leader on Thursday with a promise to build the fastest-growing economy in the G7 if he's elected.

Mark Carney was the first non-British person to become governor of the Bank of England in its more than 300-year history when he took the job in 2013. He had previously worked at the investment bank Goldman Sachs, and served as the governor of the Bank of Canada, the country's central bank.
