Update: Clean up continues after heavy rains

Yesterday, Mississauga received a month’s worth of rain over the course of a few hours that caused localized flooding in areas across the city. Mississauga experienced upwards of 106 mm of rainfall between 8 a.m. and 12 p.m. According to our conservation authorities, this weather event was slightly more intense than a 1 in 100-year storm event.

Clean up efforts and restoration of business operations

• Cleanup efforts continue across the city and include removal of debris from sidewalks, roads and trails.
• The majority of roads and parks that were closed yesterday have reopened.
• Marinas, gravel park trails and sports fields, continue with ongoing assessments regarding washouts, needed repairs and long-term damage.
• Most of the damage we’re seeing is impacting infrastructure like asphalt, pedestrian bridges, playgrounds, sports-field turf and fences.

Ongoing closures

Sports fields that remain closed (as of July 19)

• Fred Halliday Minor Ball Diamond – closed until further notice due to flood washout
• Kings Park Minor Ball Diamond #2 – working to reopen next week

Reminders for residents

Residents are reminded to take precautions in flooded areas and to respect all posted signs and barricades that have been put up for safety reasons.

For residents who may be dealing with flooding in their basements, please prioritize safety from electrical hazards and health risks during cleanup. Contact your insurance provider to report damage as they can also assist you in finding a certified contractor for repairs.

If you require additional support or want to report flood damage or a safety hazard on City property, please call 311.

Stormwater infrastructure

The City’s stormwater system and in particular the ponds and underground storage systems, served as a strong frontline defense yesterday. These enhancements were key in significantly reducing the impact of flooding. It collects stormwater from properties and carries it to a receiving waterbody. Managing this system lessens the risk of flooding, reduces creek erosion and protects water quality. This is important as it protects you, your property, aquatic habitats, wildlife and Lake Ontario.

Projects such as the construction of Lake Saigon – the stormwater management pond at Matheson Blvd. East and Hurontario Street was designed hold back flows that result in increased protection of the more flood susceptible lands downstream within the Cooksville Creek watershed.

These investments serve to highlight the importance of the City’s stormwater charge being more than just another fee for residents but a critical investment in safeguarding our community against unpredictable storms of this scale. The Stormwater Charge has made a real difference in the delivery of the City’s stormwater program.
