DEARBORN, Mich. - Ford's Oakville assembly plant in Ontario will be operating an extra week this summer in response to soaring demand for the Edge.

The Detroit-based automaker says the factory and five assembly plants in the United States will shut down for one week starting June 29 instead of the usual two-week break.

The company says the Ford Edge -- a mid-sized sport utility vehicle built in Oakville -- had record U.S. sales last month.

Canadian sales of the Edge were also strong in May after hitting a record in April.

Ford expects to make an additional 40,000 vehicles in total as a result of the extra week of work.

It's the third year in a row that Ford has shortened summer breaks to meet demand for its vehicles.
