The Durham West Jr. Lightning are a Canadian women's junior ice hockey team based in Ajax, Ontario. They are members of the Ontario Women's Hockey League.
In the 2005–06 season, Jenn Wakefield led the Lightning to a bronze medal in league playdowns and a silver medal at OWHA Provincials, setting a then-league record for most goals in a single season with 31 goals in 27 games. The next season, Wakefield's record was surpassed by forward Natalie Spooner's 32 goals,[1] as the Lightning made a run to the finals, losing to the Toronto Jr. Aeros. In 2013, after losing in the quarterfinals of the league playoffs, the Lightning won their first ever provincial championship, defeating the Stoney Creek Jr. Sabres 3–1 in the semifinals and the Mississauga Jr. Chiefs 3–2 in the finals..[2]
