Canadian steel producer Walters Group has faced a sharp drop in U.S. exports after American tariffs slashed demand, forcing the company to focus on local projects like the Calgary Flames arena. Prime Minister Mark Carney’s new quota-based tariffs aim to curb cheap foreign steel and secure Canadian jobs. Industry figures like Walt Koppelaar and Keanin Loomis hope these measures will protect the country's long-standing steel heritage and build a more resilient future.
