As one might expect of a player selected in the first round of the NHL Draft, Oleksiak has been the most celebrated athlete in his family. At least until the summer of 2016, when his sister Penny won four Olympic swimming medals as a 16-year-old at the Rio de Janeiro Games.
Penny became Canada's youngest-ever Olympic gold medalist and the first Canada athlete to win four medals at a single Summer Olympics. Meanwhile, Oleksiak has another sister who is a successful athlete: Hayley Oleksiak became a member of the women's rowing team at Northeastern University, which Jamie previously attended. He was the highest-drafted hockey player in school history when the Dallas Stars picked in him in the first round in 2011.
