Helping Mississauga Breathe Easier
Air pollution occurs year round and affects our health, the environment and the local
economy. The most persistent air quality issue in Ontario is smog. Protecting and improving
local air quality in the community is a priority for the City of Mississauga. We are committed
to doing our part to help residents breathe easier by taking special actions that make the air
we breathe safer.
What is the Citys response to smog?
One of the Citys actions to improve air quality is a response to provincial smog
advisories (or alerts) when the air quality falls below acceptable health standards. A
Corporate Smog Alert Response Plan has been developed to:
- Reduce, minimize or eliminate harmful air contaminants, greenhouse gas emissions and
conserve energy during smog alerts
- Inform residents and employees of the potential health threat and what steps can be taken
to reduce risk
What is smog?
Smog is visible as a brownish-yellow haze in the air. Smog forms when ground level ozone and
