Canadian Prime Minister Mark Carney, who said on Tuesday that the US$4.7-billion Gordie Howe Bridge would open this week, told reporters that the ceremony had been delayed "at the request of the United States."

He said the two governments were going "to work through some issues that have come up," without specifying, but that it would only be a "question of a few weeks."

"There is no great drama here," he said, dismissing speculation that tensions with U.S. resident Donald Trump had played a role.

In February, Trump threatened to fully block the bridge -- which connects the province of Ontario with the northern U.S. state of Michigan -- insisting that the United States had been treated unfairly in its construction and that it should be "at least half" U.S.-owned.
