The collapse of the Canadian Women's Hockey League (CWHL; French: Ligue canadienne de hockey féminin; LCHF) occurred in Spring 2019. Previously one of the top professional women's ice hockey leagues in the world, the Canadian Women's Hockey League (CWHL) announced on 31 March 2019 that it would be folding on 1 May, a month later. The collapse has been one of the most significant events in 21st century hockey, and continues to have a major ongoing impact on the sport, including fuelling discussions surrounding the growth of women in hockey and the creation of the Professional Women's Hockey Players Association (PWHPA).
