After the men's 4 × 100-metre medley relay at the Olympics, Hayden announced that he was retiring. He said he believed in the Canadian swim team to thrive in the future, saying that "I think in the grand scheme of things, with the people we have, we’ve done an amazing job … As long as we keep that momentum building, I think we’re going to see more success come from more diverse events."
