How much leverage does Ontario have in the U.S. trade war?

Ontario's Premier Doug Ford is actively opposing the tariffs imposed by the Trump administration on Canada, seeking to mitigate the economic impact on the province. With the U.S.-Canada trade war intensifying, Ontario's leverage comes from its significant economic influence within Canada and its strong ties to U.S. businesses. As one of the largest provinces in terms of GDP and manufacturing, Ontario's vocal opposition and negotiation strategies could shape broader Canadian responses and impact negotiations with the U.S. This matters because Ontario's actions might sway federal policies and influence the overall trade war dynamics.
