Vancouver-based Gamble and Lyakh formed High On Life with high school friend Parker Heuser after they travelled the world in 2012.
They decided to turn travel and video production into a full-time job and often promoted brands and destinations in the pictures and videos they posted from exotic locations.
Their Facebook page says: "High On Life is the attitude to embrace all of life's opportunities with a positive outlook and energy."
Last year, Gamble, Lyakh and another group member, Justis Price Brown, were banned from US federal land for five years after pleading guilty to walking on a sensitive hot spring in Yellowstone National Park and other crimes at parks across the western US.
In a statement released on Wednesday, Royal Canadian Mounted Police said they had received a call about three people swimming in one of the pools at the top of Shannon Falls.

They added that teams had "worked throughout the day to complete the complex recovery of all three people from Shannon Falls" and that the file had been given to the coroner's office.
