Climate change in Ontario
Ontario Climate Change and Health Vulnerability and Adaptation Assessment Guidelines
A toolkit to help meet the public health challenges of a changing climate in Ontario.
Public Health Climate Data
Explore case studies to learn about how data was used to impact climate related decisions.
Climate change can increase air pollutants which can cause breathing difficulties in vulnerable populations. Learn what air quality means to your health and use the Air Quality Health Index to help make decisions around your exposure.
Increased temperatures and rainfall leads to higher rates of e.coli in the water, which can cause gastrointestinal illness if swallowed. Monitor beach testing results to find out which beaches are posted as unsafe for swimming.
Blue-green algae blooms
Increased storm water run off lead to algal blooms that can cause irritations and respiratory complications. Learn how to recognize blue-green algae blooms and how to prevent them.
