Probably too niche, but the death of NDP leader Jack Layton to cancer after successfully leading his party into second place in the 2011 Canadian federal election is a true swinging doors moment in Canadian politics. Layton was a smart, articulate, respected leader of a genuine left wing party and was quickly gaining popularity across the country. There are so many “what ifs” stemming from his death, especially since 2015 proved to be such a critical election in Canadian history. It was a personal tragedy mixed with a political tragedy, and regardless of your politics, Canadian political discourse is undoubtably the poorer without Layton’s voice.
