There are three other pipelines that never came to be:
Energy
East
A proposed C$15.7 billion project (US$11.0 billion), Energy
East would have carried oil cross-country from Alberta to the Atlantic province
of New Brunswick. It was cancelled in 2017 by TC Energy in the face of
regulatory hurdles and opposition from environmental groups, particularly in
Quebec.
Northern
Gateway
This pipeline was proposed by Enbridge in 2006 to carry oil
from Alberta to British Columbia's northwest coast. The C$7.9 billion project
(US$5.5 billion) faced opposition from local and Indigenous communities who
feared the risk of a marine spill. The project died in 2016 after Prime
Minister Justin Trudeau's government cancelled its permits.
Keystone
XL
This proposed TC Energy project would have carried oil from
the oilsands of northern Alberta to the major US crude storage hub at Cushing,
Oklahoma and then on to US Gulf Coast refineries. The project was rejected on
environmental grounds by former US President Barack Obama's administration,
then revived during President Donald Trump's first administration. Former
President Joe Biden revoked the pipeline's permit on his first day in office in
2021.
TC Energy spun off its oil pipeline business in October last
year into a new company named South Bow Energy. Trump said on Monday he wanted
the pipeline built, but South Bow said it had moved on.
TC Energy has sought to recover more than US$15 billion from
the US government for cancellation of the project
