On day six, Oleksiak was seventh at the 50-metre turn of the 100 m freestyle, and eventually surged for a gold medal finish, tied with Simone Manuel and setting an Olympic record of 52.70. Oleksiak is the youngest Canadian to become an Olympic champion, the first to win four Summer Olympics medals in the same edition, and has the second most medals of the country in a single edition after Cindy Klassen in the 2006 Winter Olympics. She is also the first athlete born in the 2000s to win an individual Olympic gold. Day eight marked Oleksiak's fifth Olympic race and the only one she did not medal in that edition, being the butterfly swimmer of the 4 × 100 m medley relay that finished in fifth place. It was announced the morning of the closing ceremony that Oleksiak would be Canada's flag bearer for the event. Just days before the closing ceremony, Penny quietly returned to her home in Toronto for two days to go to Canada's Wonderland with her friends, before heading back to Rio.
