Why did Enbridge postpone the second phase of its Mainline pipeline expansion?

Enbridge postponed the 250,000-barrel-per-day second phase of its Mainline crude pipeline expansion partly because Canadian oil producers have not committed to significant output increases, and the company does not expect them to make binding final investment decisions (FID-able commitments) for new pipelines until there is greater policy and regulatory certainty in Canada.

What alternative pipeline projects is Enbridge prioritizing instead of the Mainline Phase Two?

Enbridge is prioritizing its 100,000 bpd Flanagan South Expansion and its 50,000 bpd Southern Access Extension—two secondary pipelines that connect to the Mainline in Illinois and transport crude to multiple U.S. refining centers and the Gulf Coast—over the delayed Mainline Phase Two project.
