Canada, Costello and Hockey Canada president Bill Hay, negotiated a merger between the two organizations in 1994, under the Canadian Hockey Association name, which has operated as Hockey Canada since 1998. Combining the two groups allowed for the profits from Hockey Canada events such as the Canada Cup, and the Summit Series, to be used at the grassroots level, and it also allowed access by professionals in the NHL to international competitions such as the Ice Hockey World Championships, and eventually the Olympics. Costello also spoke out against violence in sport, and was a member of the fair play advisory committee for Ontario Hockey Association. In the wake of the Graham James scandal in 1997, Hockey Canada implemented a screening program with background checks for hockey staff, and teamed up with the Canadian Red Cross to create the Speak Out against bullying and harassment, which evolved into the Respect In Sport Program. As president of Hockey Canada, Costello always recognized the volunteers who helped in the development of minor hockey in Canada. He retired as president of Hockey Canada, effective July 1, 1998 at the annual general meeting. He was replaced with vice president, Bob Nicholson, who said that Costello was a great mentor, and "made every decision based on what he thought was the best interest of the sport". IIHF council member Costello was a member of the International Ice Hockey Federation council from 1998 to 2012, after retiring from Hockey Canada. He served as chairman of the medical committee for 14 years, chairman of the Under20 committee from 1998 to 2003, chairman of the technical/arena committee from 2003 to 2008, vice president of the IIHF from 2008 to 2012, chairman of the competition committee from 2008 to 2012, sat on the IIHF Hall of Fame committee, and the statutes and bylaws committee. As part of the committees, he oversaw the inspection of Winter Olympic Games ice hockey facilities on behalf of the International Olympic Committee, helped organize international Under-20 tournaments, oversaw random drug testing, and promoted growth of ice hockey worldwide. Costelo resigned as vice president of the IIHF, effective September 30, 2012. He later remarked that "the IIHF is very much a European organization. I don’t think they would give it [the presidency] to a North American or Russian. It would give Canada too much power." Impact on women's hockey The 1990 Women's World Cup succeeded in
