I missed this when it first aired. Great conversation with Alex Himelfarb (former Clerk of the Privy Council to Chretien, Martin and briefly Harper) on taxes:

Several very interesting points made — the one about municipalities I thought was particularly good. The point about austerity being self-imposed I also thought was very important (particularly in the wake of the last Ontario election, where so many commentators were going on about how Ontario will be the new Argentina, forgetting that this is a province that, within recent memory, cut its income tax rate by 30%).
