Good riddance to this risky idea.

The two-thirds of EE that is already in the ground is older, thin-walled pipe. As evidenced by TransCanada's designs for both the new portion of EE and KXL, if the western two-thirds were being built today TC would use much thicker pipe.

Alberta, SK, Manitoba and ON would accept the ecological risks but would receive no benefit. North Dakota producers, Irving Oil and TC shareholders would be the principal beneficiaries.
