US-Canada trade war escalates after talks collapse

The US-Canada trade war escalated dramatically as talks between the two nations collapsed, leading to new tariffs on both sides.

Canadian Prime Minister Mark Carney called the US tariffs a 'miscalculation' and vowed to match them dollar-for-dollar.

US Senator Susan Collins urged the Trump administration to consider the negative impact of the tariff war.

Meanwhile, fans in Vancouver and Montreal booed the US anthem at soccer matches in protest.
