Canadian Olympic swimmer Brent Hayden has retired — again.
Swimming Canada made the announcement this morning.
Hayden won bronze in the men's 100-metre freestyle at the 2012 London Olympics.
The Mission, B.C. swimmer also won the world championship in the same discipline in 2007.
Hayden retired in 2012 but then returned after a seven-year absence, announcing his comeback in September 2019.
The oldest Olympic swimmer in Canadian history at age 37, Hayden helped Canada to a fourth-place finish in the men's 4x100-metre freestyle relay last summer at the Tokyo Games.
Hayden helped the team set a Canadian record of 3:10.82.
His leadoff leg of 47.99 made him the oldest to ever swim under 48 seconds.
He also finished ninth in the men's 50-metre freestyle, the top result among Canadian men.
