Which event significantly contributed to the growth of hockey among women in Canada?

The event that significantly contributed to the growth of hockey among women in Canada is the formation of the Women's Hockey League. This establishment played a crucial role in organizing women's hockey on a competitive level, providing opportunities for female athletes to showcase their skills, gain recognition, and participate in structured tournaments.

In contrast, events like the Winter Olympics and Montreal's Winter Carnival did help to popularize ice hockey in general but did not exclusively focus on women's participation or development. The Stanley Cup—including its purchase—primarily represents the pinnacle of men's hockey and has not directly contributed to women's growth in the sport. The establishment of the Women's Hockey League, however, created a formal pathway for women to engage in hockey, significantly impacting its growth and the visibility of female players across the country.
