Welcome to Steemit BTW.
I'm aware of the economics. Here is a quote from Andrew Sheer an hour ago.

Terrible news this morning about the Energy East pipeline. Make no mistake, Justin Trudeau is to blame.

This nation building project meant thousands of jobs and billions of dollars of investment in the Canadian economy.

Justin Trudeau’s disastrous energy policies must end. He's added new hurdles to Canadian energy producers that don't apply to foreign companies selling into Canada. He either needs to champion the Canadian energy sector, or get out of the way.
