U.S. President Donald Trump signed an executive order doubling the tariffs on steel and aluminum imports to 50 per cent.

The Canadian Institute of Steel Construction (CISC) is calling on the government to protect the steel industry from the 25 per cent U.S. tariffs.

Saint John, Calgary and Windsor are the top Canadian cities that would be most vulnerable to U.S. tariffs, according to a new report.

The removal of U.S. steel and aluminum tariffs along with all Canadian countermeasures is being welcomed by the construction industry.

To prevent diversion of foreign steel products into Canada, the federal government is imposing provisional steel safeguards on imports of seven products.

The Canadian Coalition for Construction Steel is urging the government to act cautiously before taking further action on unfair U.S. steel tariffs.
