Climate Change in the National Capital Region

August 27, 2021

The City is developing a Climate Resiliency Strategy to address Ottawa’s vulnerability to climate change and identify strategies for adaptation and mitigation, the City is developing a Climate Resiliency Strategy. 

As a part of this initiative, the City supported a Climate Projections Study in partnership with the National Capital Commission (NCC) and Environment and Climate Change Canada.

Results of the Study project that the Ottawa area will become warmer in all four seasons, and wetter in all seasons except summer. The Study also indicates that the timing of seasons will shift, that periods of extreme heat will become more common, and that conditions will become more favourable for other extreme events such as freezing rain, tornadoes and wildfires.

Under a moderate emissions scenario, the number of days where temperatures (not including humidex values) exceed 30C are predicted to more than double between 2021. ( It should be noted that global emissions are currently tracking above the moderate emission scenario.)

Better Homes Loan Program

In an effort to help reduce greenhouse gas emissions, Ottawa is developing a Better Homes Loan Program to cover the cost of home energy improvements.  A low-interest loan of up to 10% of current home value could allow homeowners to make home improvements sooner, thereby reducing both their energy bills and emissions.

Details of the program are still in development. For more information, visit the Better Homes Loan Program on the city’s website or subscribe to the City’s climate change e-newsletter.
