There are several reasons why 16-year-old Penny Oleksiak can be called a history-making Canadian athlete ā€“ her age being just one of them, according to a Canadian Olympic historian.

Oleksiak became the most decorated Canadian athlete of any Summer Olympics on Thursday, winning her fourth medal and as she stormed the womenā€™s 100-metre freestyle and set an Olympic record as she tied fellow gold medallist Simone Manuel of the United States. Oleksiak had already won one silver and two bronze medals.

ā€œIt was an incredible performance for her at these Olympic Games,ā€ Olympic historian Kevin Wamsley told Ā鶹“«Ć½ Channel on Saturday. ā€œAnd, as she said, just beyond her wildest dreams.ā€

The Toronto teenā€™s success is significant not only because of her age, Wamsley said, but also her level of experience compared to her competitors.

ā€œSo we know that a swimmer like Michael Phelps has been at multiple Olympic Games. Heā€™s almost twice as old, and you would expect a little more from him. But who couldā€™ve expected this kind of performance from a young athlete?ā€ he said.

ā€œSheā€™s only going to grow stronger and more experienced in international competitions.ā€

Canadian women have dominated the podium in Rio de Janeiro. All of Canadaā€™s 11 medals won so far have been won by women.

That female domination, led by Oleksiak, marks a major shift from the London 2012 Olympics, when men and women more or less shared the medal count equally, Wamsley said.

He added that the womensā€™ success at these Games underscores Canada's committment to fostering talented female athletes.

ā€œI think, is a measure of how sport for women is valued in Canada compared to some of the nations who are a little further behind in womenā€™s participation,ā€ he said.

Canadaā€™s biggest hope for a menā€™s Olympic medal likely rests on the shoulders of Andre De Grasse, who is set to race at 100-metre dash finals on Sunday.
