Canada imposes reciprocal tariffs on $20bn worth of US goods in response to a 25% tax on all steel and aluminium into the US.

Trump slapped similar tariffs on EU steel and aluminum during his first term in office, which enraged European and other allies. The EU also imposed countermeasures in retaliation at the time, raising tariffs on U.S.-made motorcycles, bourbon, peanut butter and jeans, among other items.
