Canadian steel producer Stelco is looking for more support from the federal government as the country’s steel and aluminum producers grapple with punishing U.S. tariffs imposed on exports of their products south of the border. Stelco Holdings Inc. president and executive chairman Alan Kestenbaum met with Justin Trudeau in Ottawa Thursday. While he thanked the prime minister for his government’s support of the metals industry since the imposition of American tariffs last year, Kestenbaum said steel producers are now facing new pressures.
