York Regional Police have issued a public warning about the dangers of climbing on construction cranes after several people have been charged in the past month and a half.

“There’s obvious dangers associated with climbing cranes that are 10, 12, 13 storeys tall. Gravity is not going to be your friend if you slip and fall. It will result in serious injury and or death,” said Const. Andy Pattenden in a video statement on Monday.

“Please stay out of closed construction sites or you may be facing some very serious criminal charges.”

In a written statement released on Monday, police said that youths, primarily, have been charged in recent incidents of climbing construction cranes.

Four separate incidents have occurred in York Region since May 22, the most recent occurring Sunday at approximately 9 p.m., when two people were spotted at the top of a 13-storey construction crane.

Police said no one was injured in any of the crane-climbing incidents, but all the apprehended parties have been charged under the Trespass to Property Act.

The warning follows a high-profile incident in April, when 22-year-old Maria Lazo was charged after she was rescued from a construction crane in Toronto.
