Live updates: Canadian tariffs take effect as Trump threatens Bombardier in growing trade war

# Why This Matters The escalating tariff war between the U.S. and Canada threatens to fracture the deeply integrated North American manufacturing ecosystem that has evolved over three decades. Bombardier, a critical aerospace supplier with operations spanning both countries, exemplifies the vulnerability of companies whose supply chains and production facilities straddle the border—tariffs targeting the company could raise costs for Boeing and other U.S. manufacturers while destabilizing Canadian employment in high-skilled sectors. Canadian retaliatory tariffs will likely hit American agricultural exports and industrial goods hard, compressing margins for U.S. farmers and manufacturers already struggling with thin profits. Without de-escalation, this tit-for-tat cycle risks unraveling trade relationships that support roughly $2 billion in daily cross-border commerce and millions of jobs on both sides of the border, potentially triggering broader economic contraction in North America.
