Natural gas is delivered by pipeline.
Local distribution companies (gas utilities) take bulk gas piped to them by wholesalers.
The distributors then pump it into a distribution main (at reduced pressure) and deliver it to service lines connected directly to individual customers. 
The first large natural gas field in British Columbia was discovered in 1951 in the Fort St. John area and aerial exploration of the Mackenzie Delta began in 1957. 
In 2010, pipelines consumed 16,946,070 GJ and emitted 1,002,851 GHGs tonnes.
