Republican senator admits Trump is Canada’s ‘adversary’ as DC delegation grovels in Ottawa - ANALYSIS: Visiting senators try to soothe hurt feelings but can do little to undo Trump’s damage, writes Jo

Ostriches on a British Columbia farm have died of the avian flu. Canada ordered hundreds of others to be culled. But two top Trump administration officials have objected.

Trump made the claim hours after King Charles III gave a thinly veiled rebuke of the US president’s attempt to annex Canada in a speech to the Ottawa parliament.

Prime Minister Mark Carney said the two nations “will cooperate where necessary, where it is in both of our interests very clearly, but we won’t necessarily cooperate.”

Trump's threat to charge the northern country comes on the same day King Charles III opened the Canadian Parliament as monarch for the first time.

Donald Trump has renewed his push for Canada to become the 51st State of the United States, just hours after King Charles III delivered a powerful speech to the Canadian Parliament.

To be competitive, Canada’s oil has to be “produced responsibly,” the country’s new energy minister, Tim Hodgson, said during a speech last week. He has proposed building carbon capture systems for the nation’s oil sands. But climate activists say now is not the time to invest even more in carbon-polluting infrastructure.
