The United States also demonstrated that tales of their demise were exaggerated as teams embarked on the long road to the LA 2028 at the World Aquatic Championships in Singapore over the past week.

Canada ended the world championships on Sunday with four gold medals, all won by the 18-year-old McIntosh.
