Trans-Northern Pipelines Inc. (TNPI) operates regulated pipelines to safely transport the refined petroleum products (gasoline, diesel, aviation, and heating fuel) used by Canadian businesses and consumers every day. These pipelines connect refineries in Edmonton to Calgary, including the Calgary International Airport; and refineries in Nanticoke, Ont., and Montreal to the Greater Toronto Area (GTA), with lateral pipelines to Ottawa as well as to Pearson International Airport and Pierre-Elliot Trudeau International Airport. In operation since the 1950s, we are committed to operating in a safe and environmentally responsible manner to protect the public, the environment, and the pipelines.
