Abstract

Canada’s crude oil and natural gas pipeline network extends 700 000 kilometres throughout Canada, except Prince Edward Island and Nunavut and is composed of pipelines and associated facilities. The vast concentration of pipelines is found in the Western Canada Sedimentary Basin (WCSB), where most petroleum exploration and production occurs.

The map shows three types of pipelines: transmission trunk lines, gathering system field lines and distribution lines. Gathering pipelines move crude oil and natural gas from wells to processing facilities. After processing, feeder lines carry the hydrocarbons to the major, long distance transmission lines. Transmission lines deliver product to small-diameter distribution pipelines, as well as industrial users, local distributors, refineries or connection pipelines to the United States.

Local distribution companies (LDCs) use distribution lines to deliver natural gas to homes and businesses. Crude oil transmission lines also transport natural gas liquids (NGLs) and other refined petroleum products, while natural gas transmission lines only transport natural gas. There are approximately 100 000 kilometres of transmission pipelines in Canada, 80 000 are natural gas pipelines and 23 000 crude oil pipelines.
