The search continues Monday for two Kitchener girls who went missing in Algonquin Park on Thursday.
OPP spokesperson Bill Dickson says the search went on throughout Sunday night utilizing multiple helicopters and a seaplane equipped with infrared scanners.
He also gave more details on the equipment the two experienced campers.
"They have a tent and some extra clothing to stay warm and they also have food that should have lasted to at least Sunday so we're hoping they can ration that."
