RCMP Sgt. Darryl Little says the extreme depth of the lake was one of the major reasons why searchers couldn't find 15-year-old Jule Wiltshire-Padfield, 19-year-old Skye Donnet and 21-year-old Hayden Kyle.
The three males were with 19-year-old Lily Harmer-Taylor when their canoe flipped on the lake May 10.
Harmer-Taylor was found soon after but died despite resuscitation attempts.
Little says the search involved an RCMP dive team and helicopter, search-and rescue members, firefighters and local residents.
He says family members of the youths have been notified of the decision to terminate the search.
