Competing at the 2018 Canadian Championships, the outcome of which would decide the composition of the Canadian Olympic team, Ilyushechkina/Moscovitch placed fourth. Both made errors in the free program, with Moscovitch stepping out of their side-by-side triple toe loop jump. As a result, they were instead sent to the 2018 Four Continents Championships, where they also finished fourth. This would prove to be their last event together, as Moscovitch announced his retirement afterward.
