Leo explained where he was and who he was with in a message accompanying the video.
He wrote, "Hello from Lake Athabasca, we're here learning about the Canadian tar sands. We took a moment to join the #IceBucketChallenge movement in support of the ALS Association. My friends Chief Adam of the Athabasca Chipewyan First Nation challenges Dave Collyer president of Canadian Association of Petroleum Producers, Chief Courtoreille of the Mikisew Cree First Nation challenges Mark Little of Suncor Canada and The Sierra Club President Michael Brune challenges Shell CEO Ben van Beurden.
He continued, "And me? In addition to a donation from my foundation, I challenge Canadian Prime Minister Stephen Harper.”
