Environment Canada has issued a special weather statement for Ajax and the surrounding region, warning residents to prepare for heavy rainfall this weekend, April 4 to April 5, 2026. A weather system known as a Colorado low is expected to bring between 25 and 50 millimetres of rain, with the heaviest precipitation occurring Saturday evening into Saturday night. Thunderstorms could lead to even higher localized rainfall amounts, creating potential concerns for the community.
While Lake Ontario water levels remain 9 centimetres below the average for this time of year—as reported in February 2026—and are not expected to exceed flood levels this spring, local authorities are urging caution. The region is currently dealing with a significant spring thaw, as rivers are affected by melting ice and snow levels that have accumulated over the winter. This accumulated snowpack holds more water than last year, which increases the risk of runoff and flooding when combined with heavy rain and warmer temperatures.
Certain areas in Ajax are more susceptible to these conditions. The Lower Carruthers area, situated between Pickering Beach Road and Shoal Point Road, is recognized as a flood vulnerable cluster due to its exposure to both riverine and shoreline flooding. Additionally, the Ajax waterfront has a history of weather-related impacts, including trail closures, erosion, and water accumulation on roads in the Paradise Beach and Lakeview Boulevard area.
The Central Lake Ontario Conservation Authority (CLOCA) continues to monitor watershed conditions and will issue further updates if necessary. Residents are encouraged to stay informed by visiting Ontario.ca/floods. If you encounter flooding or water accumulation issues, you can contact the Town of Ajax Operations Department at 905-683-2951.
