On October 21st, Canadians will go to the ballot box and return a government in Canada’s forty-third general election. The race is very close--the incumbent Liberals and the Conservatives are within a few points of one another in most polls. In episode 4 of Open to Debate, David Moscrop talks with Kevin Milligan, a professor of economics at the University of British Columbia, about some of the policy differences between the country’s top four national parties and what they might mean for Canadians.
