He's been the governor of the Bank of Canada for about five years, and helped steer our country through a serious recession.
Now Mark Carney is leaving to become governor of the Bank of England.
"I've served to the best of my abilities, and I'm humbled by the support I've received," he told a news conference today.
Carney will be the first non-British national to lead the Bank of England - and he's doing it at an important moment:
"This is a critical time for the British, European and global economies; a decisive period for reform of the global financial system including its leading financial centre, the City of London; and a crucial point in the Bank of England's history as it accepts vital new responsibilities," he said.
According to England's Chancellor of the Exchequer George Osborne (he's the equivalent of a finance minister here), Carney was chosen for one reason.
"He is quite simply the best, most experience and most qualified person in the world to do the job," Osborne said.
"We needed the best - and in Mark Carney we've got it."
Carney will remain in his role as governor of the Bank of Canada until June 1st.
We had Mark Carney in the red chair last season to talk Canada's finances, the new 100 dollar bill, and what he learned from his time as a back-up goalie for his hockey team. Wonder if those lessons will be useful in England?
