Two siblings from Milton were transported to a local hospital with minor injuries after falling upwards of 20 to 25 metres at Burlington’s Mount Nemo Conservation Area early Wednesday afternoon.

A bystander called police at approximately 2:40 p.m. after finding the two people conscious and breathing in a crevice at the park, near Guelph Line and Britannia Road.

Halton police said the victims were a 20-year-old male, who had suffered apparent head injuries, and his 16-year-old sister.

The extent of the girl’s injuries is not known.

Police said the two were taking a photo when they got too close to the edge of a drop-off and tumbled into a crevice below.

Acting Burlington Fire Platoon Chief Phil Barry said emergency crews performed a high angle rope rescue to lift both parties up to safety using a bucket-style backboard.

Halton’s Paramedics Services said both were rushed to a local hospital with minor injuries.
