The year was 1951, and Canada's population was booming. Energy shortages were becoming a problem, and the country needed to be able to supply its own energy.
A few years later, a newly formed company called TransCanada PipeLines stepped up to build what would come to be known as the Canadian Mainline – a natural gas pipeline that brought Western Canadian gas to provinces in the east.
We've come a long, long way since then. And so has North America.
As the continent's energy needs grow and change, TransCanada has remained at the forefront of the safe and reliable transportation of energy that millions rely on every single day.
