At the present time, Canada's trade deficit is running at 30 billion a year. And that ... is with a 75 cent dollar.
The 850,000 barrels per day bring in about 15 billion a year.
To fix this country, you need another 850,000 b/d - and that means Canada east.
And .. as quickly as possible. If you don't our collective living standard will start to spiral into the toilet. Since most of the Canadian economy depends on dealing with each other, don't any of you get arrogant and think that it will not affect you as well. if some fo us suffer, we all do.
Trudeau needs to deal with the 4% of the country that is First Nations and the 90 Quebec mayors and the "Greenies" who think they can play "silly bugger" just to look obstructionist.
Why not tie all the First Nation money and all the grants to the "Greenies" and the 8.5 billion a year that Quebec gets to the revenue from the pipelines. 
I wonder if they still want to be a pain, once the cash gets cut off.
