McHaffie is in her sixth year as Assistant Coach with Queen's Women's Hockey and will primarily work with the forwards and power play for the 2021-22 season.
McHaffie played five years with Queen's in a career that saw her win two OUA Championships and a CIS bronze medal while being named a CIS All-Canadian in her final year. She was the OUA MVP and also awarded the Queen's Athletics Outstanding Performance of the Year award in 2012-13.
On March 3, 2011, in a postseason game against the Guelph Gryphons, McHaffie ended the longest collegiate hockey game on record by firing home a rebound past Gryphons goalie Danielle Skoufranis in the sixth overtime period. The game lasted 167 minutes and 14 seconds.
