In April 2018, 16 people died and 13 others were injured in a bus crash at a rural intersection in Saskatchewan. The bus was carrying the Humboldt Broncos junior hockey team when it collided with a semi-trailer. Most of the dead and injured were teenagers. The crash prompted an outpouring of sympathy from people across the country, including hockey leagues, celebrities and the prime minister. We look back on the tragic events of that day and what has happened since.
