The 2016–17 season featured the return to competition of Tessa Virtue / Scott Moir, which affected the standings of the other Canadian ice dance teams. Gilles/Poirier took bronze at the 2016 Skate Canada International, the 2016 Trophée de France, and the 2017 Canadian Championships. The two struggled with mistakes in their disco-themed short dance for much of the season, with a stumble at the French event and Gilles falling at the 2017 Four Continents Championships. Gilles described the results as "physically hard and definitely tough mentally." They finished eighth at the 2017 World Championships in Helsinki.
