canadian travel to the u s falls sharply as boycott deepens amid trade tensions

The article reports a sharp decline in Canadian travel to the US due to trade tensions and tariffs, leading to a demand_spike for domestic Canadian tourism and a demand_drop for US tourism. The primary commercial mechanism is reduced revenue for US tourism-dependent businesses (hotels, attractions, border communities) and lower passenger volume for airlines serving Canada-US routes. Canadian airlines may see reduced international revenue but could benefit from increased domestic travel. The impact is region-specific (Canada-US corridor) and affects the travel and tourism supply chain.
