Trump threatens to tariff Canada over wildfire smoke choking northern US cities

Canadian leader Mark Carney says both the US and Canada have an equal responsibility to fight climate change, which experts say are worsening wildfire conditions.

A wildfire can change direction quickly with the wind. Smoke degrades air quality miles beyond the fire line, and evacuation orders can move from voluntary to mandatory in minutes.

This report is based on information from BBC World, monitored by Alert USA's verified emergency feed.

Local impacts include a high property risk, degraded air quality across a wide radius, and travel disruptions as response and evacuation operations expand.

Recommended steps: be ready to evacuate and pack a go-bag now; close windows and bring pets indoors; monitor official evacuation orders; limit outdoor activity if smoke is present.

Alert USA is tracking this wildfire and will update this report as verified information becomes available.
