Canada will take legal action under the relevant international bodies to challenge the 25% tariffs imposed by the United States on most Canadian goods, a senior government official said on Sunday, calling the tariffs illegal and unjustified.

Prime Minister Justin Trudeau set out "far-reaching" tariffs of 25%, affecting 155bn Canadian dollars' worth ($106.6bn; £86bn) of American goods ranging from beer and wine, to household appliances and sporting goods.

Prime Minister Justin Trudeau says Canada is ready to respond with 25 percent tariffs against C$155 billion worth of American goods.
