– Addressing the Hazards

The Canadian wildfires greatly affect the air quality, which is a big worry. These fires create thick smoke that contains a mix of particles, volatile organic compounds (VOCs), and harmful pollutants. Breathing in this smoke can be harmful to people’s health. These substances also pose risks to individuals who come into contact with the smoke. The pollutants can travel long distances and impact the air quality in nearby areas and even cross international borders.

It’s important to monitor the US Air Quality Index (AQI) during the wildfire season caused by Canadian wildfires. This helps address health risks associated with the fires. Stay informed and take necessary precautions to protect yourself. The AQI is a useful tool for assessing air quality levels and issuing timely warnings to the public. Keep a close eye on the AQI to reduce exposure to pollutants, safeguard public health, and prioritize the well-being of vulnerable individuals. Stay proactive and well-informed.

Alberta is currently facing 64 wildfires throughout the province, with 18 of them being out of control. Since the beginning of the year, a total of 590 wildfires have burned approximately 12,016 square kilometers of land. The state of emergency, which was declared on May 6, has now been lifted. It helped in coordinating firefighting resources and assistance for evacuees. At the peak of the situation in early May, around 29,000 people were forced to leave their homes in different communities. Currently, about 4,300 residents are still under evacuation orders. Evacuation orders are in effect for Fort Chipewyan, Dene Tha’ First Nation, Fox Lake, Chipewyan Lake, and nearby areas. The wildfires are also affecting a part of Sturgeon Lake Cree Nation. Garden River is presently under an evacuation alert.


In Quebec, there are 150 wildfires, and 110 of them are considered uncontrollable. These fires have already burned over 1,730 square kilometers of land. Premier François Legault is concerned about the Abitibi-Témiscamingue region in northwestern Quebec. The communities of Normétal and Lebel-sur-Quévillon are particularly at risk. Approximately 10,000 people have been evacuated from their homes due to the wildfires. Most of the evacuations are taking place in the northwestern Abitibi and eastern Cote-Nord regions.

Impacts of Canadian Wildfires and Response Measures

On Wednesday night, an incredibly high number of around 128 million people in the United States received air quality alerts due to wildfire smoke and ozone. This affected approximately 100 million people in 16 states. As a result, the FAA enforced air traffic restrictions around New York City, causing a temporary suspension of flights at LaGuardia Airport. The severity of air quality problems caused by wildfires is underscored by these alerts, highlighting the urgency for effective action. It is crucial to address the situation promptly and efficiently.

New York City and several other major metro areas experienced a day of orange haze caused by smoke from Canadian wildfires, leading to poor air quality on Thursday as well. The National Weather Service predicted that smoke would continue all day, causing unhealthy air conditions that would affect everyone. The issuance of air quality advisories for all five boroughs of New York City was a response to the situation. With over 8 million residents, the city required measures to address potential air quality concerns.

The Government’s Take on the Issue

Mayor Eric Adams described the situation as something that has never happened before. In response, President Joe Biden extended further firefighting assistance to Canada. This aims to support the ongoing efforts to control wildfires across the nation.

After President Biden spoke with Canadian Prime Minister Justin Trudeau, a directive was issued. The directive instructs the deployment of all available federal firefighting resources to enhance the ongoing firefighting efforts. The United States has sent over 600 firefighters, support staff, and various assets to help fight the wildfires. Their deployment aims to make a meaningful contribution to the ongoing battle against the wildfires. Canada is currently contending with more than 400 fires, as reported by the Canadian Interagency Forest Fire Centre. Out of these, 252 fires are classified as uncontrolled.
