Where did you hear that Jabberwalker? Greenpeace.
By any chance could you be talking about this?

Eastern Access: The $2.7-billion Eastern Access suite of projects establishes a path for Western Canadian and Bakken crude oil to access refineries in Eastern Canada and the midwest and eastern U.S. For example, by reversing the flow of Enbridge's existing Line 9, Ontario and Quebec refineries will have access to lower-cost Western Canadian feedstock (Ontario and Quebec currently derive 18 and 90 per cent of their crude, respectively, from higher-priced offshore sources, respectively). In-service dates for Eastern Access projects range from 2013 to 2014.
https://en.wikipedia.org/wiki/EnbridgeThey're reversing the flow of an existing line, and building up where it's weak.
Did it cross your mind that the fact Bakken and the oilsands are relatively new or expanding sources with more western energy sources coming online from Frakking might explain why they might want to reverse the flow?

How does the L3R Program fit into this equation? Line 3 is a mixed service line, meaning it carries a variety of light and heavy crude oils. Given the complexity of our system – with multiple receipt and delivery points, and the large number of crude types – the L3R Program will enhance the operational flexibility of our system, allow us to optimize throughput, and more effectively carry out Enbridge’s major market access initiatives.
“The increased reliability of throughput on our system,” notes Enbridge President and CEO Al Monaco, “will provide our customers with assured service to key markets.”
Ultimately, the L3R Program would better serve the current and future petroleum requirements of the general public, who are dependent on refineries to meet their refined petroleum product needs. At the same time, the L3R Program would reduce the frequency and magnitude of ongoing maintenance activities that would otherwise occur in order to maintain the safe operation of Line 3.
And on top of the big-picture economic benefits, the construction phase of the L3R Program itself will provide an economic boost by creating thousands of jobs and generating hundreds of millions of dollars in tax revenue.
