The leader of Ontario - Canada's most populous province - has said that American companies will be banned from provincial government contracts until the US ends the tariffs President Donald Trump imposed on Canada.
Ontario Premier Doug Ford also emphasised that his government would be "ripping up" its C$100m ($68m; £55.1) contract with Elon Musk's satellite internet company Starlink.
Governments refusing to pay people they'd contracted with? Unprecedented.
