Bombardier will cut as many as 550 employees, more than half its staff, at its rail car operation in Thunder Bay. The news is a body blow to the northern Ontario City of 110,000. Ontario Transportation Minister Caroline Mulroney said the provincial government has spoken to Bombardier executives “to express our disappointment that their company has taken this step.” In a statement, she said: “We urge the company to work with the provincial government to come to an agreement that would see jobs remain at the Thunder Bay plant.”
