A podium contender at the 2020 Canadian Championships, Schumacher placed sixth in the short program after falling on her attempted triple flip-triple toe loop combination. She placed second in the free skate, rising to the silver medal position overall. With national champion Emily Bausback lacking the technical minimum scores necessary to compete at the 2020 World Championships, Skate Canada deferred on making ladies' assignments for that event, and assigned Schumacher, Bausback and fourth-place Alicia Pineault to compete at the 2020 Four Continents Championships in Seoul. She placed fourteenth at Four Continents, finishing ahead of Bausback but four places and nearly 23 points behind Pineault.
