Chartrand's greatest disappointment came at the 2018 Canadian Championships, where the Canadian delegation to the 2018 Winter Olympics would be decided, with three spots available for ladies' singles skaters. She placed ninth in the short program and fourth in the free skate, to finish fourth overall. Chartrand completed only one of her allowed three combinations in the free skate, and finished only 5.41 points behind bronze medallist Larkyn Austman. She remarked afterward "I definitely left points out there. I skated better in my practiced this morning than I competed." As a result, she was not selected for the Winter Olympics team.
