Donald Trump’s increasingly strident approach to relations with Canada is provoking fear about the potential consequences north of the border and questions about just how serious the U.S. president-elect actually is.

"President-elect Trump has proposed various tariff plans at various times on the import of foreign goods, including a 10% blanket tariff on all imports, a 60% tariff on Chinese goods and 25% tariffs on goods from Mexico and Canada," says Ben Johnston, chief operating officer of Kapitus, a financial services firm that focuses on small business.

Supporters of the sale of U.S. Steel to Japan’s Nippon Steel are still hopeful that Donald Trump could revive the nearly $15 billion dollar acquisition.

Biden is set to announce that he'll block the takeover of U.S. Steel by Japan's Nippon Steel, thereby fulfilling one of Trump's pre-election promises.

A senior official says Canada is looking at putting retaliatory tariffs on American orange juice, sinks, toilets and some steel products if U.S.

The onetime dynamo is fighting to revive a takeover by Nippon Steel. Other tie-ups could also face obstacles, and going it alone could force cutbacks.

United States Steel Corp. CEO David Burritt in an interview with CNBC appealed to President-elect Donald Trump to rescue the company's $14.9 billion acquisition by Nippon Steel Corp.

Growth in the massive U.S. services sector picked-up in December, according to the Institute for Supply Management. Meanwhile, job openings hit a six-month high in November, according to the Labor Department.

President-elect Trump has also opposed Nippon Steel's $15 billion acquisition of U.S. Steel, which President Biden blocked last week.

U.S. Steel and Nippon Steel said on Monday that it is suing over President Joe Biden's decision to block its sales agreement and a domestic competitor and union over their actions to scuttle the deal.

Japan-based Nippon Steel has offered to give the U.S. government veto power over any potential reduction in steel output by U.S. Steel if the federal government approves a proposed merger.
