Watson first represented her country at the
2015 World Championships in Beijing, where she reached the semifinals. In July 2016 she was officially named to
Canada's Olympic team, reaching the semifinals in the
400m hurdles and finishing fourth as part of Canada's women's
4x400 metres relay team. At the
2017 World Championships, Watson finished sixth. At the
2019 World Championships in
Doha, Watson qualified to the final of the
400m hurdles with a national record time of 54.32, breaking the previous record of
Rosey Edeh that had stood since
1996. Watson competed at
her second Olympics in
Tokyo in 2021. She qualified to the semi-finals of the
400 m hurdles, but placed fifth there and did not advance to the final. The Canadian team in the
relay finished in fourth place for the second consecutive Olympics, which she remarked afterward "really hurts." Due to a back injury incurred six weeks before the Tokyo Games, Watson would later announce that she was stepping away from competition to focus on recovery. == Private life ==
