Re: If a ban on Exports would be no biggie, explain just how Canadian oil would get to market?
I think it actually would be very easy.
Take the Scenario where US oil is now not allowed to export. We have massive capacity to do so, and far better pipeline capacity to get oil from the high Northern US to the Gulf (DAPL, reversal of the Capline, etc). Plus the TMP is moving towards actually being finished on top of that...
Given that Brent prices would moonshot, whatever you lose moving Canadian oil will easily be absorbed by the price blast.
Basically, all Canadian oil will be shipped overseas, while a huge chunk of US oil heads north in Trains at a massive discount to replace Canadian oil being shipped away.
