Wildfires in Canada have been raging for weeks with more than 500 fires burning in the country, the vast majority uncontrolled. The fires are sending smoke into the U.S. and as far as Europe. Here are videos and pictures of the 2023 Canadian wildfires and their impact.

Wildfires are burning in several Canadian provinces. In Quebec, the fires were sparked by lightning. The fires raging in Alberta have an unknown cause, but this province, as well as Saskatchewan and Manitoba, have been hit with bad droughts. This and record heat have contributed to the fires.

Wildfires in Canada throughout May and June have created a record level of emissions and many of the fires show little sign of slowing down, according to the European Union's Copernicus Atmospheric Monitoring Service.

As of June 29, there were 507 fires burning in the country, with 243 out of control, according to Canada's Interagency Forest Fire Center. More than 8.1 million hectares — over than 31,000 square miles — have burned. Most fires were in Quebec or British Columbia.

The wildfires have affected air quality in many cities — and not just in Canada, but also in the U.S. The cities closest to the source will have more intense levels of smoke and worse air quality, meteorologist Jen Carfagno and hurricane and storm specialist Greg Postel, both of The Weather Channel, told CBS News.

On Thursday, Detroit had the worst air quality in the world, according to IQAir, a company that tracks air quality around the world, with Chicago coming in eleventh-worst. 

The smoke from the wildfires to the north caused "very unhealthy" air quality conditions, according to the federal AirNow site, prompting officials to urge people not to go outside for long periods of time, especially those with sensitivities.

Both Detroit and Chicago were classified as having "unhealthy" air quality as of Thursday, according to AirNow, while Minneapolis had been downgraded from unhealthy to "moderate."
