Following her pregnancy in 2018 and injury struggles in 2019, Bishop resumed competition and qualified to her third consecutive Canadian Olympic team, this time for the 2020 Summer Olympics in Tokyo. Bishop aimed to improve on her prior result in the 800 m, but placed fourth in her heat with a time of 2:02.11 and did not qualify to the semi-finals. Speaking afterward she said she was disappointed, while noting that she had been dealing with a hamstring injury, and that ultimately she was proud of what she had accomplished in returning to the Games.
