Two major pipelines carrying oil from Canada to the United States were hit by weather-related disruptions on Nov. 4, the latest hit to Canada’s oil industry just days after the Alberta government announced forced cuts in crude production.

A number of lines on the Enbridge Inc. Mainline system, which carries crude and other liquids, were hit by power outages in the Western Canadian province of Saskatchewan due to severe weather, the company said Tuesday.

TransCanada Corp.’s 590,000 barrel-per-day (bbl/d) crude Keystone pipeline was also shut due to the outage, according to a shipper on the line and traders. There was no estimated restart timeline for the line, one source said, citing a notice to shippers. The company did not respond to a request for comment.
