Mark Carney says he won’t be on the Liberal ticket if there’s an election this fall.

The former governor of the Bank of Canada and the Bank of England says he’s made a commitment to help organize the private financial sector in the run-up to the United Nations climate conference, which is scheduled to run from Oct. 31 to Nov. 12.

Carney says he can’t walk away from that commitment at such a crucial moment.
