Bonhomme made her international debut at the 2004 Four Nations Cup in Lake Placid, N.Y., and finished her career with 51 points (10 goals, 41 assists) in 107 games. She is the fifth-highest-scoring defenceman in the history of Canada's senior women's team.
The 29-year-old native of Sudbury, Ont., won gold with Canada at the 2010 Olympic Winter Games in Vancouver and at the IIHF World Women's Championship in 2007 and 2012. She assisted on Caroline Ouellette's overtime winner in the 2012 gold-medal game.
Bonhomme also won silver at the world championship in 2009, 2011 and 2013. She participated in the Four Nations Cup on eight occasions, winning six gold medals (2004, 2005, 2006, 2009, 2010, 2013) and two silver (2008, 2012).
"On behalf of Hockey Canada and Canadian hockey fans everywhere, I want to thank Tessa for what she did not only in bringing Canada success on the ice, but what she did to grow the women's game off it," Tom Renney, president and CEO of Hockey Canada, said in a statement. "She will continue to be a tremendous ambassador for the sport, and I have no doubt she will find success wherever her career leads her."
Bonhomme will continue her broadcasting career with TSN as a full-time host and reporter. She will also contribute to the network's coverage of Hockey Canada events.
