This article doesn't mention Alberta nor Texas a single time. Probably because the locale the raw materials are extracted doesn't mean much to the price at the pump.
It's not a small town market, it's multinational corporations that take from one place and send to wherever they can profit the most. Everywhere is screwed, but not more specifically than the aggregate. Both Alberta and Texas have seen the same price increases as their respective nation, because neither place has farm to table oil.
Alberta vs Canada average fuel price

Texas vs United States average fuel price

Am I reading this right that to reactivate they'd be charging the difference they 'lost' during the freeze term? Wild.
