A man is dead and another is in critical condition after a stabbing at Canada’s Wonderland early Sunday morning.

Police in York Region said they got a call around 12:30 a.m. about an incident at the amusement park, at Jane Street and Major Mackenzie Drive West, in Vaughan.

When they arrived at the parking lot, they found two men with apparent stab wounds.

One, a man in his 20s, died there. The other was taken to hospital with life-threatening injuries.

“There [was] a significant number of people here for an event,” said Const. Andy Pattenden.

“We’re appealing to anyone that may have any information on what took place here to contact York Regional Police as soon as possible — anyone that might have video … from their cellphones.”

The park’s annual Halloween Haunt event was taking place on Saturday night, but Pattenden said it doesn’t appear to be related to the stabbing.

Homicide detectives are asking any witnesses, or other victims, to call them at 1-866-876-5423, ext. 7865, or Crime Stoppers anonymously at 1-800-222-TIPS (9477).
