I believe that Canadians would not have the motivation to build more large scale refineries due to NIMBYISM, but we certainly moan when we are forced to but back the product from those that make the sacrifice.
We came very, very close to getting a new green-field refinery, that would sell 250,000 bbl/day of refined product to the Eastern Seaboard of the US, but in the end, the numbers didn't add up, and the project was cancelled. It would have been the first new refinery built in North America in decades.
