I think there might be a problem with the muskeg up north - trying to get a firm spot of ground that can withstand the weight of the pipeline. At least the mountains bear weight.

The risk, of course, is that the world oil market in 3-5 years will be sane. Might not provide enough economic return to pay for the buildout. But there’s a lot of crazies out there. Anybody actually building refineries?

Almost a year, on their hoped-for timeline, just to complete the review process. No mention of how many years to build it.

Building across the mountain ranges of BC won't be easy. And being a pipeline, not a drop of oil can flow 'till it's done.

Vs. how much quicker & cheaper might it be to build a pipeline over flat ground to Hudson's Bay, then use icebreakers to keep the tankers moving in winter? Yes, it's further to Asian markets from there. But tankers sailing around Africa are still far faster and cheaper than pipeline construction through mountains.
