Pipeline workers in Alberta have been protesting construction of the Keystone XL Pipeline, saying it will cost the region too much and hurt their jobs.
On Friday, the North American Union of Public Employees (NAUPUE) in Calgary, Alberta, took part in a rally to support the pipeline.
In response to the protests, the union called on the federal government to reverse the approval of the pipeline, which is currently in the process of approval by the U.S. State Department.
The pipeline would carry tar sands crude oil from the Alberta tar sands region of Alberta, Canada, through the Gulf Coast of Louisiana to refineries on the Gulf of Mexico.
It would be one of the largest oil pipelines ever built in the United States.
According to the Pipeline and Hazardous Materials Safety Administration (PHMSA), the Keystone pipeline has a potential to cause a total of 3,946 fatalities in the U:S.
The pipeline is scheduled to cross the U.:S.
border twice before being built in Canada.
On Thursday, workers in a North Dakota oilfield protested against the Keystone Pipeline at a protest site.
The protesters said that the pipeline would be dangerous to the health of the local community and that it would have a negative effect on the environment.
The protest in North Dakota came as President Donald Trump signed an executive order on Friday that would open up new pipelines in the country’s oil and gas belt.
Trump’s executive order also allows for the construction of a pipeline through a protected national wildlife refuge in southeastern Montana, which the Obama administration had declared a national monument.
The White House has said that it has a plan to approve the Keystone and Dakota Access pipelines, which would run through national parks in the southern half of the U., as well as through other places in the northern half.
