Justin Trudeau steps down, flu cases in Canada, and more

Prime Minister Justin Trudeau now says he isn’t the best choice to lead the Liberals into the next election, and he will step down as soon as the party picks another leader. That leader will also automatically become prime minister. There are warnings the party constitution could leave the campaign open to foreign interference. Trudeau says his main regret from his time in office is not getting electoral reform done. Opposition leaders Pierre Poilievre and Jagmeet Singh say it’s time for a federal election. Several premiers have already signalled their biggest concern: that the federal government needs to keep its eye on relations with the U.S.
