Heavy rains release partially treated wastewater into Lake Ontario

By Announcement, Resources, Ward 1

BRAMPTON, ON (July 16, 2024) – Due to recent heavy rains and subsequent flooding, an overflow of partially treated wastewater from the G. E. Booth wastewater treatment facility has been released into Lake Ontario. The exact amount of water is unknown at this time. Partial bypasses are common during high rainfall events.

The drinking water supply remains clean and safe for consumption. Our water treatment facilities are operating effectively, ensuring the highest standards of water quality.

Heavy rains can flush pollutants into water bodies. Residents are advised to refrain from swimming or engaging in any water-related activities along the Lake Ontario beaches in Mississauga until further notice. Please check the beach water testing site for the most recent results.

Peel Region is closely monitoring the situation and will provide updates as more information becomes available. We encourage residents to stay informed through our official communication channels.

Final Update on Weather Event – July 16, 2024

By Announcement

Final Update – Weather Incident – July 16, 2024

Provided by the Director of Works Operations & Maintenance – Regarding the City’s response to yesterday’s weather event, which saw Mississauga receive a month’s worth of rain in just one day, (over the course of four to six hours) – which exceeded the 100-year storm event. The update provides details regarding the overall impact on various infrastructure assets, the questions addressed through the media, and ongoing clean-up efforts.

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 remained closed today as field conditions and infrastructure is evaluated for safety of play.
  • Trails that remain closed include Culham Trail, Sugar Maple Woods Trail and Streetsville Memorial Trail along the Credit River. Barricades and signage are being put in place for safety and residents are being asked to avoid these areas.
  • Courtneypark Drive East is closed from Netherhart Road to Britannia Road East for the next few days.

Stormwater infrastructure

  • Our stormwater infrastructure did its job. Every time a storm of this size occurs, it prompts a crucial discussion about funding our infrastructure. The City’s stormwater system and in particular the detention ponds and underground storage systems, served as a strong frontline defense yesterday. These enhancements were key in significantly reducing the impact of flooding.
  • 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.

Public inquiries and emergency response

Mississauga Fire and Emergency Services

  • Mississauga Fire and Emergency Services responded to more than 160 incidents, which included numerous water rescues and an evacuation of 113 seniors from a long-term care home.
  • No injuries or deaths were reported as a result of the storm.
  • Throughout the day, MFES provided crucial assistance in various emergencies including rescuing individuals trapped in flooded and stalled vehicles, conducting welfare checks for citizens/business owners trapped by rapidly rising floodwaters, responding to reported fires and searching for individuals swept into a creek (Cooksville Creek and the QEW).
  • MFES has partnered with Global Medic to provide those who have been displaced with essential hygiene kits.

311 Call Centre

  • 311 received twice their daily call average. From 7 a.m. to 7 p.m., more than 2,000 calls were triaged, leading to 150 significant flooding event service requests being dispatched.
  • 38 calls were related to property damage from water flooding basements, 10 of these calls were from the Lisgar area.
  • The rise in call volumes resulted in somewhat longer wait times, averaging around 4 to 5 minutes, with the majority of calls focused on:
  • Flood emergency
  • Maintenance of Catch basins
  • Non-emergency clean up
  • Parking enforcement
  • Water outside of home


  • Received more than 100 calls about fallen trees and branches across the city, impacting roads, sidewalks, and trails.
  • Calls were prioritized based on safety hazards. Cleanup operations are slated to continue over the coming weeks.


  • Flooding occurred on the transitway for a short period of time and nine MiWay bus routes were detoured. Operations have been restored back to normal as of today.


  • Power outages within Mississauga were limited.
  • At the peak of the event, Alectra Utilities advised there were approximately 313 customers without power in the City Centre area (Confederation Parkway and Kirwin Drive), with an estimated restoration time of approximately 5 – 7 p.m.
  • Currently approximately 13 customers remain without power as a result of flooded equipment. Power is expected to be restored before end of day.

Key data and insights from the weather event

The rain began just before 9 a.m. and stopped around 2 p.m. Rainfall had mostly stopped in Mississauga by approximately noon. While rain amounts varied throughout the city, Mississauga received approximately 106 mm of rain yesterday. This is in addition to approximately 16 mm of rainfall that occurred on Monday, and 14 mm of rain that fell on Sunday.

The Credit Valley Conservation (CVC) is reporting that it received between 27-118 mm across their watershed.

For context, during the storm in July 2013, about 128 mm of rain was reported to have fallen in a span of roughly 90 minutes.

According to Credit Valley Conservation, the rainfall amounts received during yesterday’s storm, were slightly more intense than a 1 in 100-year storm event. This does not mean that this event is only expected to take place every 100 years, but that it has a one per cent chance to occur in any given year.

Although weather forecasters and Environment Canada had issued warnings about the storm, the weather models had not predicted the volume of rain that ultimately fell. There was very little lead time to prepare for this event.

Reminders for residents

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

We’re also advising residents who have called in to report flooded basements, to watch for electrical and health hazards, as they clean up and to advise them to call their insurance company to assess damages. Their insurer will recommend a qualified contractor to evaluate and restore any damages. 

Thank You to Staff

A heartfelt thank you is extended to all City staff and crews for their swift and diligent efforts to address safety hazards throughout the event, ensuring the safety of Mississauga residents and minimizing damage.


UPDATE – Mid afternoon:

As you may be aware, it will take some time for the flooding to subside even though the rain has ended. Our City staff have been actively managing the flood situation from earlier today. Efforts have been concentrated on:
– Addressing flooding on walkways, streets, open spaces, and trails
– Replacing dislocated manhole covers
– Unclogging catch basins
– Supporting the Police with implementing roadblocks

Our 311 team has also been handling a significant number of calls about flooding incidents affecting streets, personal properties, and parks, and responding effectively.

Updates on road closures

Flooding has led to the temporary closure of several roads:
Britannia Road West and Ninth Line
Falbourne Street
Greenpark Crescent
Kennedy Road and Courtney Park Drive
Bridge on King Street between Camilla Road and Frayne Ave
Matheson Boulevard at Timberlea Road
Mississauga Road and QEW
Paisley Boulevard East (effecting Catherine Jean Lane and King Street East)
Paisley Boulevard and Sheppard Ave
Queen Frederica Drive
Queensway and Stanfield Road
Torbram Road at the Railway underpass

Park and trails closures

Additionally, the following parks and trail areas are inaccessible due to the floods:

Sport fields
All major City-owned soccer, baseball, football, and cricket fields for the day. Our team will re-evaluate the fields tomorrow morning on whether they are fit to reopen to the public.

Reminders to residents
We are reminding all residents to please refrain from calling 911 unless they are in immediate danger or require assistance with rescue or evacuation. We urge everyone to steer clear from stormwater facilities, streams, and rivers, as many are either at peak levels or have overflowed. Currently, our MFES teams have reached their capacity for water-related rescues, with four boats already deployed and more calls coming in.

Our City crews are persistently working to mitigate the impacts of flooding on City-owned properties. Due to the current weather conditions as well as the heavy rains Mississauga experienced yesterday, we are seeing localized flooding in areas across the City and in some areas street closures and park walkways are being closed. All creeks and rivers are either at capacity or flooding into parks and greenspaces. At this time, the majority of water is staying within these floodplains. The intensity and volumes we are seeing today were not identified in yesterday’s forecasting models and monitoring systems; this modelling was just updated within the last couple of hours and our City crews are responding quickly.

As a result of current weather conditions, crews are responding to high volumes of service requests related to:

  • Flooding issues on sidewalks, roads, parks and trails
  • maintenance hole covers being dislodged
  • clearing blocked catch basins
  • assisting Police with road closures

Calling 911

  • Please do not dial 911 unless you’re in immediate danger or require assistance with rescue or evacuation.

Basement Flooding

If your home or basement has flooded, remember to be careful.

  • Don’t attempt to shut off electricity if any water is present.
  • If water rose above your electrical outlets, baseboard or furnace, immediately call Alectra at 1-833-253-2872 to report it.
  • If you live in a condo or apartment, please contact property management if you are currently displaced from your home.
  • For updates on when you can return to your property, please contact property management

Exercise Caution

  • Avoid stormwater ponds, culverts, streams & rivers.
  • Never travel through flooding or areas where there is ponding.
  • Be sure that roof water drains.
  • Ensure eavestroughs & downspouts are clear.
  • Keep catchbasins debris-free. Report blocked catchbasins to 311.
  • Use caution when travelling in areas where flooding has or could occur.
  • If you are driving, travel to conditions, leave extra space for stopping, watch for taillights ahead and be prepared to stop.
  • If walking or cycling, use designated crosswalks or crossrides where possible.
  • Report any fallen trees and flooding to 311.
  • Report power outages to @alectranews.

Peel Regional Police Update: Project OFFRAMP

By Announcement, Resources

This year, Peel Regional Police led a Joint Forces Operation called Project Offramp, targeting street racing and stunt driving with officers identifying and actively patrolling hotspot locations across the Greater Toronto Area.

Working with neighbouring agencies, they investigated 933 vehicles and issued 2,140 Provincial Offence Notices, including:

  • 96 Stunt Driving Charges
  • 246 Improper/No Muffler Charges
  • 24 Criminal Code Charges Related to Impaired and Dangerous Driving

Curbing illegal street racing and stunt driving remains a top priority. They have several ongoing strategic and targeted enforcement initiatives designed to address this type of behaviour, as they know it can have tragic implications for our community. Despite consistent efforts to enforce and raise awareness on the dangers of street racing and stunt driving, Peel Regional Police recognizes that these activities continue to be a public safety concern across Peel Region.

PRP are always looking to identity additional measures and initiatives to deter and curb this type of behaviour on our roads, to keep our roads safe for everyone.

Art Gallery of Mississauga – Across Latitudes

By Announcement, Events

Across Latitudes examines the intricate realities of moving between cultures and across generations in the process of forging identities and locating our place in the world. The distinct art practices of Soheila Esfahani, Heidi McKenzie, and Zinnia Naqvi all draw from experiences of diaspora to explore the complex terrain of cultural migration and commodification.

This exhibition highlights the artifice of sites and objects that are intended to represent national identity—images in postcards, gift shop trinkets—and how they simplify and misrepresent the realities of lived experience. The works shown here consider the uncomfortable impact of such commodities on the process of shaping personal identity and aim to unravel the stereotypes they perpetuate. By holding these objects up for examination, and by integrating a diverse range of culturally significant markers of personal identity, such as traditional motifs, family and archival photographs, and mementos from childhood, these three artists engage in creative acts of revisiting, reworking, and reclaiming to offer new interpretations and meanings.

The artists in this exhibition inscribe, in different ways, their experiences of belonging amid the construct of what it means to be Canadian. Turning to their uniquely individual paths of migration—with diasporic roots in Iran, the Caribbean, and Pakistan—their works counter the limitations of myth-making and foreground the multi-dimensionality of intercultural experience.

Important Update – Upcoming NAV CANADA Flight Checks: Second Semi-annual Test

By Announcement, Events

NAV Canada regularly conducts instrument landing system (ILS) check at Toronto Pearson. This is a routine operation that ensures the accuracy and safety of the country’s navigation aids and instrument approach procedures. The ILS is a precision approach system that provides navigational guidance signals and information on a cockpit display to guide pilots accurately to the point of landing in periods of poor visibility.

The second semi-annual test of 2024 will take place for two nights during the week of July 22-26 from approx. 12:00AM to 4:00AM and will involve all runways at Toronto Pearson. It will take approximately 20 minutes per runway.

Pre-approved flights do operate in the overnight hours in accordance with the Night Flight Restriction program in effect between 12:30 am and 6:30 am. However, given that the flight checks will involve flight patterns of repeated approaches for the runways at varying combinations of height, speed, and direction, we wanted to inform you that there might be noise impacts in your riding.

We have already posted the information on our Noise Advisory Calendar, and will also be posting a message on WebTrak.

Affected residents can feel free to reach out to the Toronto Pearson Noise Management Office directly if they have any questions or wish to submit a noise complaint:

NOTICE OF PRE-DESIGN FIELD INVESTIGATION Beach Street Sewage Pumping Station Diversion Aviation Road, Caven Street, East Avenue, Hampton Crescent, Lakeshore Road East, and Lakeside Avenue

By Announcement, Resources, Ward 1

Beach Street Sewage Pumping Station Diversion Aviation Road, Caven Street, East Avenue, Hampton Crescent, Lakeshore Road East, and Lakeside Avenue

Peel Region is undertaking investigations related to the installation of a new sanitary sewer system in your area. Sanitary sewers are underground pipes that carry wastewater from your home to a wastewater treatment plant. Wastewater is created when water goes down the drain or is flushed down the toilet. As pipes age and our population grows, we need to repair and replace older sewers to keep providing high quality wastewater services to you.

As we plan for future construction, we will be in your neighborhood conducting field investigations along Aviation Road, Caven Street, East Avenue, Hampton Crescent, Lakeshore Road East, and Lakeside Avenue.
• We will survey your street and use temporary spray paint or flags to mark the location of underground gas, hydro, and cable on roads, driveways, and lawns.
• We may drill holes to collect soil samples, determine ground conditions, or confirm utility locations. These holes may be drilled in the road or the municipal right-of-way, the land owned by the municipality between the street and your water service box. (A water service box is a small, round metal valve in your driveway or lawn that typically marks your front property line.)
• We will take pictures and record video to help ensure that we restore the area as close as possible to its former condition, after construction takes place.
We expect these activities to take place between July 2024 and May 2025.

Contractor and working hours
The work will be completed by various contractors under contract to Peel Region. The contractors normal working hours are from 7 a.m. to 7 p.m., Monday to Friday. These hours are consistent with the City of Mississauga bylaws.

Traffic impacts
There may be minor traffic disruptions during these activities. If we must reroute traffic, we will place signs giving directions.

Staying informed
To receive updates on Peel Region construction projects in your area, sign up for e-notices at to start signing up.
