The Globe and Mail reports in its Friday, Jan. 24, edition that National Bank of Canada chief executive officer Laurent Ferreira says Canada needs to protect its national interests in response to a looming trade war with the United States, including implementing what he calls a "Buy Canada" act. The Globe's Stefanie Marotta writes that President Trump has reignited the debate over productivity and competition as the U.S. administration plans to ease corporate taxes and regulations, according to Mr. Ferreira. He says: "We should aim to have a more competitive tax regime for businesses in Canada. ... We should start thinking about Asian and European markets." To strengthen Canada's economy and counteract tariffs, the government should leverage its strengths in energy, natural resources, agriculture and manufacturing, according to Mr. Ferreira. He proposes that Ottawa introduce legislation for procurement, research and development, and artificial intelligence in defence and national security, given rising geopolitical tensions with Russia and China and increasing defence costs linked to NATO obligations. Several bank CEOs say potential tariffs could damage the economies of this country and the U.S.
