Things seem to come in threes.
IF it was here in the US, I’d say they are simply needing to raise the price of fuel. On the other hand, it might just be a coincidence!!!
Canadian oil production has soared in recent years. It has almost doubled in a decade. I don’t know how much is refined in Canada vs exported as crude.
I am very happily surprised there have been few devastating oil train explosions like the one that leveled a Quebec town a few years ago. I see those trains traveling through Milwaukee and Chicago.
I remember a cracking tower incident and separate a fire at the El Segundo refinery in the 1950’s. Also a oil tank farm fire that must involved tens of millions of gallons of crude oil in San Pedro same era.
