Flavio Volpe, president of the Automotive Parts Manufacturers’ Association (AMPA), travelled to the U.S. capital Monday to join Ontario Premier Doug Ford and others in telling the Americans that protectionism would cause immense economic pain on both sides of the border.

Ontario is set to introduce legislation with measures intended to tackle illegal blockades at international border crossings.
