Trump plans 50% tariffs on Canada for auto and steel imports starting January 1, 2027

The Trump administration is planning to raise tariffs on Canadian auto and steel imports to 50%, with the new rates set to take effect on January 1, 2027.

The tariff timeline so far

Section 232 tariffs already impose rates as high as 50% on imports of steel, aluminum, and copper derivatives, though certain exemptions have softened the blow for specific commodities.

In August 2026, the administration threatened to impose 50% tariffs on multiple Canadian goods under Section 338 of the Tariff Act of 1930. The legal justification centers on allegations that Canada has treated US exports unfairly, a characterization Ottawa has vigorously disputed. The effective date for those threats was August 19, 2026.

Negotiations hanging by a thread

In August 2026, negotiations explored the possibility of lowering Canadian auto tariffs to 15% and steel and aluminum tariffs to 25%.

Exemptions have emerged as a key bargaining chip. Energy products, potash, and critical minerals have been carved out of certain tariff actions.

Canada has retaliated with its own surtaxes and quotas on US products, creating a tit-for-tat dynamic that has become the defining feature of North American trade relations.

What to watch heading into 2027

If negotiations gain traction and the 15% auto and 25% steel/aluminum rates discussed in August become the landing zone, markets could breathe a sigh of relief. If the full 50% takes effect as scheduled, expect supply chain disruptions and cost inflation to hit fast.
