The United States has expanded its trade pressure on Canada by threatening tariffs on a specific list of goods that disproportionately affects small and medium-sized enterprises in sectors such as electronics and cosmetics.

This development marks a shift from broad-based industrial threats to targeted measures that could severely impact companies with less capacity to absorb cost increases or pass them on to consumers.

The proposed duties follow earlier threats by US President Donald Trump to impose 50% tariffs on a wider range of Canadian imports, citing environmental disputes over wildfire smoke.

While the broader macroeconomic impact remains uncertain, the focus on niche manufacturing and consumer goods introduces new volatility for mid-cap Canadian exporters.

Investors are now assessing which firms face the most direct exposure to these potential levies.

Canadian Prime Minister Mark Carney has responded by stating that the government is evaluating "all options" in response to the escalating trade tensions.
