Moore-Towers/Marinaro began the 2015–16 season with a bronze medal at the 2015 U.S. International Classic – their first Challenger Series event. Competing in the Grand Prix series, they won bronze at the 2015 Skate Canada International and placed seventh at the 2015 Rostelecom Cup. During the short program at the Canadian Nationals, the two clipped blades as they began the twist lift, resulting in a hard fall. They finished fourth for the second year in a row. On March 11, Moore-Towers/Marinaro were added to Canada's team for the 2016 World Championships after Julianne Séguin / Charlie Bilodeau withdrew due to injury. They placed eighth at the event in Boston.
