Donald Trump has launched another furious attack on Canada - and threatened to hit the country with tariffs so big they 'will be read about in history books'. The US president stepped up his North American trade war today with a new announcement of steep 50% tariffs on all Canadian steel and aluminium - effectively doubling the measures he had previously announced.

When the MAGA crowd sang Donald Trump‘s praises and promised everyone that a glorious new golden age awaited America at the end of the line, I think that turning the country’s oldest and biggest ally into an enemy and ruining the economy as a result was not exactly high on their list of priorities.

Donald Trump explosively warned Ontario that it would "pay a financial price" for its retaliatory tariffs "so big that it will be read about in History Books for many years to come"
