Live updates: Canadian retaliatory tariffs loom; Big Tech opposition grows as midterms approach

# Why This Matters The escalating tariff war between the US and Canada threatens to raise consumer prices across North America while fracturing a critical political coalition ahead of the midterm elections. American technology companies, which have largely avoided the tariff disputes so far, are now facing potential supply chain disruptions and retaliatory measures that could squeeze their profit margins—and their stock prices, which remain central to voter sentiment about the economy. Canadian tariffs on US agricultural products and industrial goods will hit politically sensitive sectors in swing states, particularly affecting farmers and manufacturers already operating on thin margins, while simultaneously pressuring tech executives to publicly oppose a trade policy backed by a significant portion of their customer base. This puts Republican candidates in the difficult position of defending tariffs that risk alienating both business donors and working-class voters concerned about prices at checkout counters before Election Day.
