The trade war between the United States and Canada is entering a fresh and increasingly contentious phase, with US President Donald Trump turning his attention to Canadian aircraft manufacturer Bombardier and threatening to restrict its access to the American market. Trump has accused Canada of pursuing protectionist trade policies and criticized the country over restrictions affecting American aircraft manufacturer Gulfstream. He has warned that Bombardier jets could face restrictions in the United States unless the company shifts more of its production to American soil. Canadian Prime Minister Mark Carney has pushed back against Washington's pressure, vowing to defend Canadian workers, businesses and families while keeping the door open for negotiations. Carney has also said Canada cannot simply wait for Washington and is seeking to expand the country's trade relationships with other global markets. WATCH
