Under A Yellow Sky: What Today’s Toxic Haze Means For Toronto And Those With Nowhere To Go

If you stepped outside yesterday, and looked up, you probably thought you were staring at a scene from a movie. The entire city has been covered in a strange, yellowish-orange haze that completely hid the skyline. But don't worry, it is not the apocalypse.

The unusual color of the sky is actually from the massive wildfires burning in northwestern Ontario. There are over 100 active fires right now, and the wind has carried the thick smoke over a thousand kilometers straight into the Greater Toronto Area. Because the smoke is so thick, Toronto woke up on Wednesday morning with the worst air quality of any major city in the entire world, hitting a maximum "very high risk" level of 10+. Meteorologists say these fires are incredibly intense due to recent record-breaking heat, and they won't get fully under control immediately. The smoke is expected to choke the city until at least Friday, when a new weather system and rain are finally supposed to move in and clear the air.

For most people, this means a ruined day. The city even had to cancel outdoor activities and modify public programming just to keep people out of the toxic air. Most of us can simply go inside, shut our windows, and turn on the AC. But for Toronto's unhoused population, there is no escape.

When you live on the street, you cannot avoid the outdoors. This air crisis hits the homeless population the hardest, especially since it is mixing with a brutal heatwave that has pushed temperatures past 30°C and triggered extreme heat warnings across the city. Breathing this heavy smoke for hours is incredibly dangerous. It causes immediate eye and throat irritation, and it drastically raises the risk of asthma attacks, heart issues, and heat stroke for individuals who have nowhere to shelter. Without access to sealed indoor spaces, clean air, or running water, Toronto's most vulnerable residents are left completely exposed to a double health threat: toxic air from above and extreme heat from the ground. 

Tips for Staying Safe Outdoors

  • Wear the Right Mask: Normal cloth or surgical masks do not protect your lungs from smoke. If you must go out, wear a tight N95 or KN95 mask to filter out the dangerous particles.

  • Avoid Hard Work: Since the bad air is mixing with extreme heat, try not to exert yourself. Drink plenty of water and focus on staying cool.

  • Keep Indoors Clean: If you have a place to stay, keep all doors and windows shut. Put your air conditioner on a recirculating setting so it does not pull the outside smoke into your home.

Resources for Toronto’s Vulnerable Community

  • City Cooling Spaces: The City of Toronto opens air-conditioned public spaces during heat and air alerts. Check the city website or call 311 to find the nearest open cooling center.

  • Drop-In Centres and Shelters: Local spaces like the Scott Mission, Fred Victor, and St. Felix Centre offer indoor shelter, clean water, and relief from the thick air.

  • Street Outreach Teams: The city's outreach teams are actively walking the downtown core to hand out water, check on people, and help transport them to indoor shelters. If you see someone struggling in the heat or smoke, call 311 to send an outreach team, or call 911 for a medical emergency.
