uhhh we do refine in both provinces. Imperial, Suncor, Shell refine to fuel in edmonton and then there's the Co-op refinery in Regina.
Look at the redwater upgrader disaster... years in now and still fuct up bad.
great example of how we (Alberta) are soo behind on infrastructure AND dont successfully build anything on time... EVER
A lot of the issue is in functional design.
Not quality of construction or timelines.
But ya not a smooth go at all
