“This expansion demonstrates our commitment to innovation, operational excellence, and customer satisfaction," said Pat D'Eramo, Chief Executive Officer of Martinrea International Inc. "It further expands our capabilities as a global supplier in Canada and prepares us for future growth opportunities. We thank our employees, customers, and the local community, who have been instrumental in our success.”
