The National Post reports in its Thursday, July 23, edition that Westerners might be experiencing a sense of deja vu as Ontario Premier Doug Ford is once again suggesting an embargo on oil exports to the United States to retaliate against tariffs. The Post's Rahim Mohamed writes that Ontario Premier Doug Ford told reporters at the first ministers' meeting in Charlottetown on Tuesday that Canada should leverage its most valuable resources to hit back at the U.S. after the White House announced plans for new tariffs this week. "No matter if it's the electricity -- and I'm not speaking for the other provinces, I'm going to be very clear -- the potash, the oil -- they need to feel the pain," said Mr. Ford. Last year Mr. Ford suggested the same tactic, but met immediate resistance from Alberta Premier Danielle Smith and Saskatchewan Premier Scott Moe. The new 50-per-cent tariff is expected to hit Ontario, Quebec and British Columbia the hardest, while leaving Alberta and Saskatchewan relatively unscathed. Ms. Smith said Tuesday that she did not support Mr. Ford using Western resources as a weapon. From Charlottetown she said, "That's not going to happen." Crude oil and potash are Canada's top export to the U.S.
