Emergency crews responded to Stoney Trail, near 114 Avenue S.E., at 11:00 a.m. for reports of a single-vehicle crash.

A 25-year-old man was the only occupant in the vehicle and was pronounced dead at the scene.
Police say speed does not appear to be a factor in the crash but they are looking into whether drugs or alcohol were involved.
