Canada will announce C$29.8 bln in retaliatory tariffs on the United States on Wednesday in response to U.S. President Donald Trump’s steel and aluminum tariffs, a Canadian official said.

The official declined to be named.

Trump’s increased tariffs on steel and aluminum imports took effect on Wednesday as prior exemptions, duty free quotas and product exclusions expired, and as his campaign to reorder global trade norms in favor of the U.S. gains momentum.
