Yet another spat over territory is rocking the troubled US-Canada relationship – and it’s not a result of a Donald Trump threat to turn his northern neighbor into a 51st state.

The Canadian government says it is working with the US Federal Aviation Administration, General Dynamics Corp. and Bombardier Inc. to address certification issues for some of Gulfstream’s private jet models after a complaint made by President Donald Trump.

Former Canadian Prime Minister Stephen Harper says the country should make “any sacrifice necessary” to preserve the independence of the country in the face of threats from U.S.

Donald Trump has threatened Canada with a 50% tariff on any aircraft sold in the US. It is the latest salvo in the US president’s trade war with America’s northern neighbour as his feud with Canadian prime minister Mark Carney expands.

In a speech to party members before the party vote, Poilievre did not mention U.S. President Donald Trump's name despite the president's ongoing threats to Canada's economy and sovereignty.

Nearly six years after pleading guilty to a crime that should have made him inadmissible, Jeffrey Epstein visited Canada, and federal government officials are providing no answers about why he was allowed into the country.

The president said he would restrict the use of Canadian-built aircraft and impose a 50 percent tariff on them until the dispute was resolved.

Trump's new threat comes on the heels of a previous warning of a 100 percent tariff on goods imported into the U.S. from Canada.

Canada’s economy is on life support, the nation is in a clear recession, and the Bank of Canada needs to cut interest rates further, says an economist.
