A female believed to be in her 20s has died after a single-vehicle crash in East Gwillimbury Sunday night.

It happened near Yonge Street and Old Yonge Street at around 11 p.m. Sunday.

Police said it appears that the vehicle went over the guard rail at a bend in the road and fell down an embankment where it then rolled over.

According to police, one female was pronounced dead at the scene.

It is unclear if anyone else was inside the vehicle at the time of the crash.

Old Yonge Street and Yonge Street in Holland Landing was closed for several hours as police extricated the vehicle from the embankment. The roads have since reopened.
