The Power Panel discusses how the outcome will change the face of the Carney government and its approach to the House. Plus, former House of Commons senior parliamentary counsel Steven Chaplin says he hasn't found any Canadian or Commonwealth precedent for assembling a majority this way, and explains why the Liberals will still need rules changes if they want their majority control to extend to House of Commons committees.
