Canada’s largest oil refinery is looking for new supply options as the U.S. war on Iran threatens one of its most reliable, and long-standing, sources of crude oil. Irving Oil recently got permission from federal regulators to use a foreign-owned ship to bring crude oil from Newfoundland’s offshore fields to Saint John, in southern New Brunswick. As recently as 2018, nearly half of the refinery’s supply was Saudi crude. Irving pushed back, arguing Alberta oil was more expensive to ship to Saint John than Saudi crude. Cenovus Energy, which delivered Western Canadian crude to Irving by tanker in 2020 and operates some of the Newfoundland sector, said it would leave it to Irving Oil to comment.
