Infrastructure Minister Catherine McKenna has decided not to seek re-election. Her surprise decision opens up some prime political real estate that could become a launching pad for former Bank of Canada governor Mark Carney should he decide to run for the Liberals in the next election. McKenna has held Ottawa Centre, a riding that encompasses Parliament Hill, since 2015, when she wrestled it away from the New Democrats. Carney has not committed to running but promised in April, during his political debut at the Liberal party’s virtual convention, to do whatever he can to support the party. McKenna is to hold a news conference Monday to announce her decision to stand down in the next election, but an advance copy of her remarks was obtained Sunday by The Canadian Press. “When I got into politics now eight years ago, I made two simple promises to myself: always fight for what I believe in and leave when I had done what I got into politics to do,” the speech reads. She says she wants to spend more time with her three children and devote her professional energies to the fight against climate change.
