Oil companies have built pipelines in Canada to move petroleum since 1862. But the construction and operation of major long-distance oil and gas pipelines that cross interprovincial and international borders did not commence until the mid-20th century, following the discovery of enormous volumes of crude oil and natural gas near Leduc, Alta., just south of Edmonton.
