Canada can replace Russia in global energy market - expert The G7 countries should completely abandon the purchase of natural resources and energy from Russia, replacing them with Canadian ones. The opinion was expressed by the head of the G7 research group at the University of Toronto, John Kirton. “The G7 must still pressure India to stop buying Russian oil. But equally important, G7 members must fully ban imports of Russian energy - oil, coal, natural gas, uranium. Canada, with the world’s fifth-largest oil reserves and as a top-three uranium producer, can help fill the gap,” Kirton said.
