RIO DE JANEIRO (Reuters) - Brazilian planemaker Embraer said on Friday that the U.S. Department of Commerce has shown that the Canadian government "heavily and illegally subsidized" Bombardier and its C Series aircraft, allowing the company to survive and distorting the aviation industry.

The statement came just after Bombardier won an unexpected trade victory against U.S. planemaker Boeing Co when a U.S. agency rejected imposing hefty duties on sales of Bombardier's new CSeries jet to American carriers.
