Climate change is expected to impact Ontario in many ways. Understanding these impacts and how we are vulnerable to climate change will determine how we address expected changes. Adaptation involves taking action to minimize the risks, take advantages of opportunities and ultimately increase resilience to the negative impacts associated with climate change.

Expected impacts of climate change in Ontario include:

  1. increases in heat-days combined with poor air quality and its adverse affects on human health;
  2. decreases in Great Lakes water levels;
  3. increased risk to the Boreal forest as a result of drought, pests and fire;
  4. extreme precipitation events causing (flash) flooding;
  5. damage due to both aquatic and terrestrial invasive species.
