The United States' 25% tariff has officially come into effect, with President Donald Trump declaring there is no turning back. Trump emphasized that Canada has no chance of avoiding the tariffs or negotiating a deal. In response, Canadian Prime Minister Justin Trudeau has announced retaliatory tariffs of 25% on $155 billion worth of American goods. Trudeau stated that these tariffs will remain in place until the U.S. withdraws its own. With tensions escalating, the trade war between the U.S. and Canada is set to intensify, impacting businesses and global markets.
