Canada explains trade war options, including the Welland Canal

CBC News answered reader questions about how Canada could respond to U.S. tariffs and trade pressure, focusing on possible measures such as export taxes, sales bans and restrictions on key goods. The article says economists and government figures have different views on whether Canada should target U.S. energy exports or other products. Some experts warn that broad retaliation could raise costs for Canadians and strain trade ties, while Prime Minister Mark Carney has said he does not see value in using energy exports as a bargaining chip. It also addresses whether Canada could block U.S. ships using the Welland Canal. The piece explains that the St. Lawrence Seaway is jointly overseen by Canada and the United States, and that closing the canal would likely hurt businesses on both sides and raise legal concerns.
