On his way to competing for Canada at the 2016 Summer Olympics, Rodney became just the second Canadian man to run the 200 m in under 20 seconds when he ran a 19.96 at the national trials in Edmonton, beating favourite Andre De Grasse. The win came just weeks after his mother almost died of a brain aneurysm. In July 2016, he was named to Canada's Olympic team. In addition to winning a bronze medal with the Canadian relay team, he competed in the men's 200 metres event, placing third in the seventh of the preliminary heats.
