I am going to answer this with a focus on a long-term strategy, and clearly a metre under the ground, the cost efficiency opportunities and the Canadian leadership around safety in pipelines are second to none in the world.
In Canada we will need sustained energy infrastructure even as we transition to alternative forms of energy. Any of the big energy reports point to a very long run on the use of fossil fuels as we continue to mitigate GHG emissions.
It's fundamental to Canada that we have good energy infrastructure. Pipelines are absolutely the way to go on that. That's why you see so many separate projects under proposal, the most current one being the northern gateway that will have a decision from the independent panel by the end of this year, and one will consider then where to go.
