1. Where is credible link made between these pipes and Canadian domestic oil supply by producers or government? Is the Globe asserting these pipe projects will offset middle east oil imports? Where has that been agreed to by any oil producer/shipper/government?
2. What will "severe economic pain" be if pipes aren't built? After years of following pipeline stories I have yet to see a reliable cost-benefit given global oil markets dictate price -- not Canadian supply. 
3.. No mention of how Canada will meet GHG targets given upstream increases in output from Alberta in order to fill these pipes. But right balance has been struck?
