I think there were a couple of reasons.
The main reason was that the contract model from the outset was awarded to one contractor for the entire spread of the project, and it would have been better to diversify the contractor pool for that length of the project, at 890 kilometres.
At the same time, you had tight labour markets with Site C under way, as well as LNG Canada and Coastal GasLink, so it would have been much more advisable for the project proponents to sit down and work with the Pipe Line Contractors Association and unionized contractors to figure out how to get our members deployed across the country to better deliver and construct that pipeline.
