Canada will likely wait for U.S. to investigate leaks: expertOTTAWA — A national security expert says Canada will likely wait for American security services to investigate an apparent leak of Pentagon documents that appear to detail U.S. and NATO operations in Ukraine, rather than launching a probe of its own. The leaked documents describe claims, which The Canadian Press has not independently verified, by Russian-backed hackers that they successfully accessed Canada's natural gas infrastructure. "These intelligence leaks are bound to have some kind of impact on the intelligence relationship between the United States and Ukraine, which is so important to both countries," he said.
