Transmission pipeline basics

Transmission pipelines are large, underground pipelines that safely and responsibly transport oil and gas products over long distances.

Canada’s extensive network of pipelines spans more than 840,000 kilometres right across the country. While there are different types of pipelines in Canada, the information on this website focuses on the large, long-distance transmission pipelines that are operated by members of the Canadian Energy Pipeline Association (CEPA). These highly sophisticated “energy highways” are the safest, most environmentally responsible and most efficient way to transport large quantities of natural gas and oil across long distances.

Transmission pipelines deliver 97 per cent of Canada’s oil and natural gas – energy that every single Canadian counts on. They also deliver Canada’s responsibly-produced energy to markets around the world and generate billions of dollars every year for the Canadian economy.

As the world transitions to a lower-carbon energy future, pipelines will continue to play a critical role in delivering responsibly produced Canadian natural gas and oil to global markets.
