Recent analyses show diverging trends in cross-border traffic between the U.S. and Canada, with some regions reporting sharp declines in passenger and freight movements.
These fluctuations highlight the vulnerability of North American supply chains to economic shifts and political disruptions. The disparity between regional data suggests that tariffs and local blockades are creating uneven pressures across different border corridors.
In the Montana-Canada region, the impact has been severe. Traffic across this border dropped during the first 11 months of 2025 [2]. A reporter for the Daily Interlake said the decline was the steepest in three decades [2].
Other regions have experienced different patterns. In the Windsor-Detroit corridor, the Canadian Border Services Agency (CBSA) noted a short-term increase in truck volumes just before blockades occurred. A CBSA spokesperson said the agency processed 106,274 drivers in the week preceding the blockades [1].
Economic factors continue to drive these changes. Nearly 90 percent of companies reported changes to freight movement amid tariff adjustments [4]. These shifts are causing operational strain for those moving goods across the border. John Slipp said operators are feeling the pinch as cross-border travel continues to wane [3].
While some trackers suggest freight volumes are rising as companies adjust to tariffs [4], other regional data contradicts this trend. The New Brunswick-Maine crossing has also seen declines in travel, contributing to the mixed outlook for regional operators [3].
“Traffic across the Montana-Canada border has dropped, the steepest decline in three decades.”
The conflicting data suggests that there is no single trend governing US-Canada border traffic. While some companies are successfully adapting to new tariffs by shifting freight volumes, regional hotspots like Montana are experiencing historic lows. The short-term spike in truck volume before blockades indicates that logistics companies are attempting to front-load shipments to avoid potential disruptions, creating a volatile cycle of congestion and decline.
