Meanwhile, Trump posts video of himself kicking over a Lake Ontario sign and replacing it with Lake America sign

Donald Trump and Canada continued a verbal duel on Saturday over the US government’s administrative renaming of Lake Ontario, with the Ontario premier erecting a giant sign saying “Lake Ontario. Now and Always” – and the American president posting a video of him tearing down an avatar of that sign, erecting a replacement saying Lake America, and dancing to YMCA.

Rhetoric over the naming of Lake Ontario is the public face of an escalating trade dispute between the US and its northern neighbor involving a 50% US tariff on Canadian steel and retaliatory tariffs from Ottawa.

The Canadian province's premier, Doug Ford, installed a billboard-sized sign on the lake's shoreline after the US president signed an executive order on Thursday directing US federal agencies to change the lake's name on US maps, documents and databases to 'Lake America'. Ford told reporters that the lake's name, which is more than 400 years old, would remain unchanged. Trade talks between the US and Canada collapsed last week, with each side ‌blaming the ⁠other for derailing three days of intensive negotiations
