ATCO was originally founded as Alberta Trailer Hire in 1947 by S.D. Southern and his son, R.D. Southern to service Alberta's booming oil industry. From initial revenues of just $1,077.00, ATCO is now a multi-billion dollar corporation. With a consistent vision of strong, sustainable growth, ATCO has built and acquired numerous diverse companies around the world, some with histories of service dating back to the early 1900s.
