They say the simulated gunfire is part of a training exercise.
The scenario is designed to test communication, emergency plans and police response to a potential emergency.
Several RCMP units are taking part, along with BC Ambulance, Burnaby Fire Department and officials from SFU.
The exercise begins at 9 a.m. and wraps up by 1 p.m.
A section of University Drive northwest of the academic quadrangle will be closed during the exercise.
