Canadian wildfires are continuing to pour smoke along the East Coast of the United States, including the New York City area, which Wednesday afternoon, appeared red like it was on the planet Mars.

Canadian officials have reached out to other countries to help fight the more than 400 fires across the country that have displaced 20,000 people.

The Canadian officials also said this is shaping up to be the nation’s worst wildfire season ever, after being sparked on drier-than-usual ground and accelerating quickly.

In Quebec, more than 100 fires were burning uncontrollably Tuesday.

One of the biggest concerns from the fires is the air quality.

New York City is experiencing its worst air quality in recorded history, per FOX Weather’s analysis of EPA historical data, affecting millions of people.

NYC officials like Mayor Eric Adams and health and emergency management officials warned residents to remain indoors as much as possible and limit their time outside. If residents must go outside, officials suggested masking up.

"As haze and smoke from Canadian wildfires continue to spread, much of New York State is expected to experience unhealthy air quality today," New York Gov. Kathy Hochul posted to Twitter. "Please take steps to stay safe. Stay indoors if possible and limit strenuous activities."

The governor also posted an update from the New York Department of Environmental Conservation and issued another Air Quality Health Advisory tomorrow for all of New York, except for the Adirondacks.

Because of the smoke, the Federal Aviation Administration grounded all planes at New York City’s Laquardia Airport on Wednesday.

Delays are also expected at other area airports.

Many other officials turned to Twitter regarding the fires.

The mayor of Ottawa. Mark Sutcliffe, said he was very concerned about the conditions and sympathetic to those who have reduced lung capacity and asthma, and might be having difficulty today.

Ottawa Public Health advised citizens to keep an eye on their health symptoms as the Air Quality Health Index continues to degrade.

"If you experience symptoms such as tightness in your chest, wheezing or shortness of breath, seek medical attention," the agency said.
