Despite being defending gold medalists in the 4x200 at the 2019 World Relay Championships, Rodney and the Canadian relay team failed to advance out of the heats in the 4x100 m relay. Competing at the 2019 World Athletics Championships in Doha, Rodney placed thirteenth in the heats of the 200 m, and did not advance. In a disappointing finish, the Canadian relay team did not advance to the 4x100 m final despite having the eighth-fastest overall time due to their running in the faster of the two heats.
