Born in Montréal, Québec, Missy lived most of her life in Surrey, British Columbia, with her father, a minister; her mother; and two sisters. She began her career in front of the camera at age eighteen when she started modeling. The print advertisements soon turned into commercials. It wasn't long before Hollywood came calling.
A dedicated soccer player, Missy's schedule has forced her to take time away from the sport, but she picks up games whenever she can. She also enjoys snowboarding and outdoor sports on the local Vancouver mountains. She resides in Vancouver with her family.
