Park started practicing taekwondo as a toddler and had earned her black belt at her parents' taekwondo school in Winnipeg by the age of seven.[11]
She broke through in the taekwondo world when she won the gold medal on home soil at the 2016 World Taekwondo Junior Championships in Burnaby, Canada, where World Taekwondo released an article about her, after her performance naming her a "Star of Tomorrow".[12] She would later say of her win the competition that " "I don't think I really realized before how big of a moment it would be if I won. "They named me 'the next new face of taekwondo.'"[13] Following this, Park won her first major medal at the 2019 World Championships, taking a bronze after losing to Jade Jones in the semi-finals.[14] Park was favoured to win a medal at the 2020 Summer Olympics though she suffered a loss in the quarterfinals, ending the medal hope.[15]
At the 2023 Pan Am Games, Park won her third event in a row, winning the gold by defeating Maria Clara Pachecho of Brazil who had defeated her that year at the world championships.[15] After the win she said spoke of her earlier losses and rediscovered success saying that "after Tokyo, a lot of it for me was mental. Dealing with that pressure and expectations, having that belief [to succeed]. It's come together, and the confidence and belief is there now. A big thing is enjoying myself in the ring. When there's pressure, expectations and noise outside of what you're doing, it can, at times, become not fun. But the reason I was successful from a young age and why I love the sport is because I love to do it."[15]
