Canada wildfires are raging across the country with more than 900 active blazes scorching about 3 million hectares of land as of Wednesday. Recent hot, dry weather has triggered these fires, with the greatest concern in the Northwest Territories and Ontario where several remain out of control.
Impact of Canada Wildfires on Air Quality
The wildfire smoke has caused poor air quality across affected regions. Winds have carried the smoke into the United States and even across the Atlantic to northern Europe. Residents in impacted areas are advised to limit outdoor activities and use air purifiers.

Health Risks from Smoke Exposure
Exposure to wildfire smoke can lead to respiratory issues, eye irritation, and cardiovascular problems. Vulnerable populations including the elderly, children, and those with pre-existing conditions should take extra precautions.
Comparison of Wildfire Seasons: 2024 vs. Prior Years
| Year | Active Fires (Peak) | Hectares Burned |
|---|---|---|
| 2024 | 900+ | ~3 million |
| 2023 | ~650 | ~2 million |
| 2022 | ~400 | ~1.5 million |
This year’s wildfire season has already surpassed recent years in both fire count and area burned. The risk of further blazes remains high as North America enters peak fire season.
El Niño and Global Weather Patterns
The strengthening El Niño is contributing to extreme weather worldwide. In Argentina, the city of Salta recorded its warmest-ever overnight minimum temperature of 26°C (79°F) during mid-winter — a remarkable event driven by the Zonda wind and the Foehn effect.
Tropical Storm Activity in the Pacific
El Niño is also expected to increase typhoon activity. Tropical Storm Noul formed north of the Philippines and is forecast to intensify into a typhoon, tracking between the Philippines and Taiwan before making landfall on China’s southeast coast.
Key Takeaways
- Over 900 Canada wildfires are currently burning, covering 3 million hectares.
- Smoke has spread to the US and Europe, causing air quality issues.
- El Niño is driving unusual warmth in Argentina and boosting typhoon activity.
- Stay informed and prepared as wildfire season peaks.
