After five years of delays and rejections, TransCanada has finally received approval from the U.S. government to build the cross-border section of its Keystone XL pipeline — but construction is unlikely to begin for at least a year.
Approval of the line was announced March 24 by President Trump alongside TransCanada President Russ Girling. Girling brought with him Sean McGarvey, president of the North America's Building Trades Unions, and representatives from Quanta Services, which will build the pipeline.
