A 21-year-old man is dead and another is in hospital with life-threatening injuries after a double stabbing in the parking lot of Canada's Wonderland in Vaughan, Ont., early Sunday.

York Regional Police say the stabbings occurred in the parking lot shortly after midnight, as the amusement park's Halloween Haunt event wrapped up.

One man was pronounced dead on the scene and the other was rushed to hospital with life-threatening injuries, police said. He remained in serious condition in the afternoon.

Forensic investigators cordoned off a large section of the parking lot Sunday morning and remained on scene through the afternoon.

The amusement park north of Toronto remains open and has not cancelled its annual Halloween Haunt event, which runs from 7 p.m. to 12 a.m. until Halloween.

A Wonderland representative told CTV Toronto that staff do not believe the stabbing was connected to the event, and that metal detectors at entry gates would have prevented anyone with a weapon from accessing the park.

The metal detectors were installed in 2003 after a man was shot and killed as the park was closing for the night.

The Wonderland official said the park has turned over security camera footage to investigators.

Police have not released any information on possible suspects at this time. They are asking witnesses and any others injured in the stabbings to contact police immediately.
