The early December oil spill in Kansas means that TC Energy Corp.’s Keystone pipeline has now leaked more crude oil than any other conduit on U.S. land in the past 12 years.

An unremitting shipping logjam in the waters outside of Los Angeles already has contributed to higher costs, delays and intermittent goods shortages across the U.S. Now, it could be to blame for California’s biggest oil spill in 27 years.

Canadian and Alaskan crude that normally travels to the U.S. West Coast is finding a market in China, where demand is almost back to pre-pandemic levels.

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 heavy crude has become so cheap that the cost of shipping it to refineries exceeds the value of the oil itself, a situation that may result in even more oil-sands producers shutting operations.

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

Canadian shipments of crude by rail are poised to surge next year, spurring investment in new export infrastructure.

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.

Heavy Canadian crude isn’t getting cheaper, but that hasn’t stopped companies from splurging on costly rail shipments.

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.
