The longtime Liberal riding of LaSalle-Émard-Verdun in Montreal was lost to the Bloc Québécois, while the NDP kept the Winnipeg riding of Elmwood-Transcona. Mackenzie Gray explains why this still might not be enough to trigger an early election, and Mercedes Stephenson reports on how the Liberals are now effectively giving the Opposition a chance to defeat the government.
