After college, Clark intended to play professionally in the Canadian Women's Hockey League (CWHL), but with its abrupt discontinuation, she joined the Professional Women's Hockey Players Association (PWHPA), advocating for a more sustainable model for women's hockey. Clark's dedication to the sport paid off as she helped lead Team Harvey's to victory in the PWHPA Secret Cup championship in 2023, showcasing her scoring prowess with a hat-trick in the final. In 2023, following the consolidation of the PWHPA and the Premier Hockey Federation into the new Professional Women's Hockey League, Clark signed with PWHL Ottawa Charge, demonstrating her commitment to the growth and development of women's hockey. Internationally, Clark has represented Canada with distinction, competing in prestigious tournaments such as the Winter Olympics. Notably, she contributed to Canada's success at the 2018 Winter Olympics, where they won a silver medal, and the 2022 Winter Olympics, where they secured gold.
