Trans Canada Highway is an EP by the ScottishIDM duo Boards of Canada. It was released on 29 May 2006 by Warp Records. According to Boards of Canada's official site, the EP was originally scheduled for release on 6 June 2006. (That date being written numerically as 6/6/06, harking back to their use of the number 666 on the album Geogaddi.) The original retail vinyl release of the EP was pressed on white vinyl, while re-issues were pressed on black.
The EP contains the duo's first ever music video, directed by Melissa Olson. The video pieces together various found video and film clips in order to create a short narrative to the song "Dayvan Cowboy", which also appears on Boards of Canada's 2005 album The Campfire Headphase. The video begins with stock footage of Joseph Kittinger's landmark sky dive in 1960, from a helium balloon that had pierced the atmosphere, effectively leaving Kittinger in free fall from space. The video then shows footage of Laird Hamilton landing in the ocean after his parachute successfully opens. As he rises to the surface, he grasps a surfboard and begins to ride waves.
