US President Donald Trump has signed an executive order to rename Lake Ontario to Lake America, a move linked to ongoing trade disputes with Canada.

• The executive order directs the US Department of the Interior to update the name change within 30 days.
• The renaming follows the collapse of trade talks and the US imposition of new 50% tariffs on $20bn worth of Canadian goods.
• Canadian officials, including Prime Minister Mark Carney and Ontario Premier Doug Ford, have rejected the name change, asserting the lake's historical name.
