Trump decertifies all Canadian aircrafts, threatens 50% tariffs

US President Donald Trump has decertified all aircraft made in Canada, including Bombardier Global Express, until the latter country certifies American-made Gulfstreams. He also threatened to impose 50% tariff on any and all Canadian aircraft sold in US if "this situation is not immediately corrected". "Canada is effectively prohibiting the sale of Gulfstream products in Canada," he said.
