Enbridge Inc. is a multinational pipeline and energy company headquartered in Calgary, Alberta, Canada. Enbridge owns and operates pipelines throughout Canada and the United States, transporting crude oil, natural gas, and natural gas liquids, and also generates renewable energy. Enbridge's pipeline system is the longest in North America and the largest oil export pipeline network in the world. Its crude oil system consists of 28,661 kilometres of pipelines. Its 38,300 kilometre natural gas pipeline system connects multiple Canadian provinces, several US states, and the Gulf of Mexico. The company was formed by Imperial Oil in 1949 as the Interprovincial Pipe Line Company Limited to transport Alberta oil to refineries. Over time, it has grown through acquisition of other existing pipeline companies and the expansion of their projects. Enbridge has been responsible for several oil spills, including a spill on Line 3, which was the largest inland oil spill in the US. Opposition to Enbridge projects has resulted in several popular uprisings, most notably the Dakota Access Pipeline protests, and the Stop Line 3 protests. Wikipedia
