Coquitlam RCMP worked with search and rescue teams to locate two young children, ages six and seven, from Burke Mountain.
Efforts began late Sunday night when the children and their father were hiking a trail on Burke Mountain.
All three fell down a steep cliff, according to Coquitlam RCMP, and while the father was able to make the difficult climb up the cliff to get help, the children stayed on the mountain until rescuers arrived.
Three Search and rescue teams, including Coquitlam, North Shore and Maple Ridge, managed to locate the children. Also aiding in the search were a helicopter, a drone and a police dog.
The children have been located and are being long-lined out of the forest by helicopter to awaiting ambulances.
Quarry Road was closed this morning for the rescue and police were planning a press conference at 10 a.m. at the site.
