Mounties say the woman was walking alone on Sunday night when a man grabbed her from behind.
RCMP say the woman was not hurt and managed to break free from the man's grip, but the suspect ran off and officers have not been able to locate him.
The suspect is described as an 18- to 20-year-old man with olive skin, spiky short black hair, and a medium build.
Police say the incident is probably isolated and not related to a string of on-campus assaults in 2013.
But Cpl. Brenda Winpenny says the public should stay aware of their surroundings, especially while walking alone late at night or early in the morning. (News 1130)
