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 unwind decades of integrated North American supply chains, with immediate consequences for consumers and businesses on both sides of the border. Canadian retaliation targeting American agricultural exports, whiskey, and manufactured goods will hit politically vulnerable sectors in swing states just weeks before the midterm elections, potentially fracturing Republican support for Trump's trade policies at a critical moment. Beyond electoral politics, sustained tariffs on cross-border trade could slow economic growth, raise prices for everyday goods, and force manufacturers to choose between absorbing costs or relocating operations—reversals that would be difficult to undo even if trade tensions cool. The timing amplifies the stakes: tech companies are now actively opposing further escalation, suggesting the business community's patience with protectionist measures may be eroding faster than Washington anticipated.
