Climate Change and Flooding

Climate change is increasing the frequency and intensity of floods in Canada, with significant economic losses and public health risks. Over 1.5 million homes are in high-risk areas, and annual flood damage costs could grow three to five times by mid-century. Recommended government actions include restricting development in high-risk zones, enhancing protection infrastructure, and supporting proactive relocation.

• Climate change is increasing the frequency and intensity of flooding in Canada because warmer air holds more moisture, leading to heavier rainfall and more intense storms. This is compounded by rising sea levels and melting snow packs.
• Extreme rainfall events are becoming more frequent; a 1-in-20 year event could occur every 5 to 15 years by the end of the century, with 24-hour extreme precipitation projected to increase by 5% to 12%.
