Alberta's Jason Kenney is the latest Canadian premier to take aim at U.S. Democrats, calling out presidential hopefuls who want to block the Keystone XL pipeline expansion.

The Trump administration on Wednesday approved a right-of-way allowing the Keystone XL oil sands pipeline to be built across U.S. land,

Top U.S. House Democrats have called for a federal review of the Keystone pipeline and the agency that regulates it in the wake of 1.4-million-litre spill in North Dakota.

An oil spill from the Keystone pipeline in North Dakota has turned out to have affected almost 10 times the amount of land as first reported, a state regulator said Monday.

There's a disconnect between the Kenney-Blanchet feud and the issues that actually matter right now, Rob Breakenridge says.

The company says it will operate the pipeline at a reduced pressure with a gradual increase in the volume of crude oil moving through the system.

The Keystone pipeline is to remain shut down until TC Energy takes corrective action aimed at determining the cause of a 1.4-million litre oil leak in North Dakota.

TC Energy Corp. says its net income slipped in the third quarter after it sold $3.4 billion in assets in the first nine months of the year.

North Dakota regulators say the Keystone pipeline leaked more than 9,000 barrels of oil in the northeastern part of the state.

Calgary-based TC Energy Corp. says it is investigating a possible incident after detecting a drop in pressure near its facilities at Edinberg, N.D.
