Husky Oil said a leak from one of its pipelines on Thursday spilled about 200,000 liters, or around 1,250 barrels, of heavy oil mixed with a thinning chemical into the North Saskatchewan River near the US border. Canada's largest integrated energy company said it shut the pipelines, part of its Saskatchewan gathering system, which halted the release, CBC reported. The pipeline was moving heavy oil with a product called diluent, which helps the oil flow. The spill into the river was noticed as a gloss on the water Thursday morning. It entered the river about 30 kilometers east of Lloydminster. The provincial government confirmed the leak and noted Husky activated an emergency response team and measures were immediately taken to contain the spill. Husky said the company was working closely with authorities and area municipalities. Spokesman Mel Duvall said in an email that the oil was in a line that runs from the company's heavy oil operations to its processing facilities in Lloydminster.
