Oil plunged to the lowest in two decades amid a record collapse in U.S. fuel demand and the biggest-ever weekly build in domestic crude supplies.

Canadian crude rebounded from a one-year low after inventories fell and Alberta’s premier pledged to defend prices.

U.S. refiners want more Canadian oil, and pipeline companies are finding ways to get it to them. Companies are adding space to their congested oil export pipelines from Canada even as plans for bigger expansions and new lines face delays.

Tanker trucks laden with oil are journeying almost 500 miles to pipeline and rail terminals. It’s a phenomenon that Ken Boettcher, president of Three Star Trucking Ltd. in Alida, Saskatchewan, started to see three or four months ago when oil shippers around Kindersley, near the Alberta border, began requesting trucks to move their crude, in some cases, as far south as North Dakota.
