Marc Garneau looks back on his time as an astronaut and Trudeau Cabinet minister. He talks to Paul about truth telling in politics, why he stuck around after being ousted from Cabinet, and his thoughts on the current political landscape, from the fate of the Liberal party to Quebec sovereignty. 

Marc Garneau’s new autobiography is called A Most Extraordinary Ride: Space, Politics, and the Pursuit of a Canadian Dream.

Season 3 of The Paul Wells Show is sponsored by McGill University’s Max Bell School of Public Policy.
