In which country was the 1st World Women's Hockey Tournament (1987) held?

The 1987 World Women's Hockey Tournament was held April 21–26, 1987, in North York, Toronto, Ontario. It was the first major world tournament for national women's ice hockey teams and was the first unofficial tournament before the International Ice Hockey Federation (IIHF) launched the Women's World Championship in 1990. The success of the tournament and the positive reports presented to the IIHF gave women's ice hockey the legitimacy needed to pave the way for the creation of the modern Women's World Championship.

The six-day tournament was held at the North York Centennial Arena. Team Canada won the tournament defeating Team Ontario by 4–0 in the final game. The championship trophy was named the Hazel McCallion World Cup, in honor of Mississauga mayor and women's ice hockey advocate Hazel McCallion.

The following teams played at the tournament. It is assumed that these teams were selected on an invitational basis, but that is not confirmed: Canada, Netherlands, Japan, Ontario, Switzerland, Sweden, United States.

The seven participating teams played in a single round robin tournament format. The top four teams from the group proceeded to the Medal Round, while the remaining teams played in the placement games. Games were 45 minutes long, three periods of fifteen minutes each.
