Truckers in Manitoba worry about changes at the international border if the U.S. can't come up with a solution to their budget crisis.

Unless Congress and the White House can come to an agreement on the budget, massive cuts to U.S. Border Services will come into effect on March 1.

Terry Shaw, general manager of the Manitoba Trucking Association, said no one knows how the cuts could shake down, but it could mean major delays at the border.

The Canadian Trucking Alliance is lobbying in Washington to try and get legislators to understand the impact if such cuts go through, Shaw said.

"We've talked to the people on the front lines. I called down to the assistant port director at Pembina, North Dakota, yesterday and she was just as concerned as we are right now," he said.

Two thirds of Canada's goods move by trucks to the U.S.
