Newest US President Joe Biden, through a Presidential order, revoked a critical presidential permit for the 300 miles long, Keystone XL oil pipeline, a big blow to Western Canadian economy. Earlier Democrats did stop construction of the pipeline, which would have carried crude oil from Alberta, Canada to the Gulf Coast of the US, in 2015. Environmentalists strongly objected to the $8 billion pipeline that includes the Green Party of Canada and National Democratic Party of Canada.
