US President Trump has threatened to impose a 50% tariff on Canadian goods, and Canada has cancelled the joint celebration of the opening of the Gordy Howe International Bridge with the United States. The spokesperson for the Canadian Minister of Infrastructure stated that the Gordy Howe International Bridge, which costs CAD 6.4 billion (approximately USD 4.5 billion), is still scheduled to open on July 27th. However, due to the threat of trade action from the United States, it is no longer appropriate to continue holding celebration events.
