Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On October 1, 2018, we closed the sale of the provincially regulated facilities of our Canadian natural gas gathering and processing businesses for proceeds of approximately $2.5 billion. Refer to Note 6. Acquisitions and Dispositions for further discussion of the transaction. The BC Pipeline T-South System moves natural gas into the Pacific Northwest region and is comprised of two pipelines that run parallel to each other. On October 9, 2018, a rupture occurred on one of the natural gas transmission pipelines within this system and ignited at the site. Both pipelines were shut down following the rupture. Following various assessments and National Energy Board approval, both of the pipelines were returned to service at a lower operating pressure. We are cooperating and working with the Transportation Safety Board in its investigation to determine the cause of the incident.
