There are two major problems with Energy East:
- Most of  its 1.1 mbpd would be surplus to the three refineries that it could serve. It's one thing to assume environmental risks for a hazardous product that our population requires. It's another thing for six provinces to assume environmental risks to supply other countries.
- Two-thirds of EE's length will be converted older pipe. Although the new section of EE would be built with generous wall thicknesses and state-of-the-art coating, the existing pipe is quite thin-walled (mostly 3/8") and several decades old.

The environmental risks from EE outweigh its potential economic benefits.
