Pipelines in Canada
Canada has 88 pipelines mapped on the OverWatts open energy atlas — the 9th-largest fleet of the 110 countries that hold any, and 2% of the world's mapped total. Of these, 67 operating and 10 under construction or proposed.
The largest owner-operators are Enbridge (23), TC Energy (9) and NOVA Gas Transmission Ltd (7) — Enbridge alone is named on 26% of them. Half of Canada's pipelines in service predate 2015 (median commissioning year of the 53 with a known date), 26 came online in the past decade and the oldest still listed is Trans Mountain Oil Pipeline, dating from 1953. 10 are in the pipeline, led by FortisBC Pipeline — Eagle Mountain-Woodfibre Gas Pipeline, under construction. They account for 5% of every energy asset OverWatts maps in Canada.
