After 11 years in federal politics, former Conservative leader Erin O’Toole gave his last speech to Parliament before retiring this summer. In a session that has been marked by heated partisan attacks, O’Toole warned members of Parliament that performance politics is fueling polarization and respectful debate is taking a backseat to social media gratification. ‘The West Block’ host Mercedes Stephenson sat down with O’Toole to discuss the growing division of partisan lines, whether the Liberals are taking national defence seriously, and the government’s handling of foreign interference.
