Residents of a community in northwest Mississauga are several weeks away from being better protected from devastating floods with the opening of a \u201ccritical\u201d piece of new infrastructure, the city says.<\/p>\n
The third pumping station to be built in the Lisgar area of west Meadowvale is \u201cexpected to be fully operational in July,\u201d City of Mississauga Ward 10 Coun. Sue McFadden told residents in an update on Tuesday.<\/p>\n
\u201cTesting of the control panel has already taken place and further testing of the rest of the equipment is taking place over the next several weeks,\u201d the councillor said in her latest newsletter to the community. \u201cFollowing successful testing, the pumping station will remain operational and will join two previously built stations further north along the Sixteen Mile Creek in helping to reduce residential flooding in the area.\u201d<\/p>\n
The new station is located along Sixteen Mile Creek, immediately south of Doug Leavens Boulevard.<\/p>\n
Fourth pumping station to open in 2027<\/p>\n
McFadden added \u201cthe detailed design of a fourth station, planned for the east edge of Osprey Marsh just south of Osprey Boulevard, is complete and construction is scheduled to begin later this summer.\u201d<\/p>\n
That puts the fourth facility on track to open in 2027, the city said earlier.<\/p>\n
In her update to constituents, McFadden said all four pumping stations, when operational, are designed to regulate the amount of stormwater within the Foundation Drain Collector system and automatically pump water out of the FDC sewers when it reaches a pre-determined level.<\/p>\n
\u201cThis creates space in the system and reduces the chances of a surcharge of water backing up toward basement foundations,\u201d she added. \u201cThis mitigation measure is in addition to the High Water Protocol that the city invokes whenever significant rain or thunderstorms are forecast in the area.\u201d<\/p>\n
The city\u2019s High Water Protocol involves trucks towing powerful pumps to three locations along the creek to \u201cmanually monitor water levels in the sewer and activate pumps whenever too much water enters the system.\u201d<\/p>\n
Earlier this year, McFadden said the new pumping station \u2014 and the one to be operational in 2027 \u2014 \u201cwill help with all of the flooding that we\u2019ve been experiencing in the Lisgar community.\u201d<\/p>\n
Flooding problems date back two decades<\/p>\n
Area residents have dealt with flooding for the better part of two decades. The flooding of homes in their community dates back to 2008 and two pumping stations were built earlier in efforts to address the problem.<\/p>\n
Residents pleaded with Mississauga\u2019s mayor last September<\/a> to use her political clout to fast-track completion of the fourth pumping station being built to help mitigate the flooding problem. That facility, to open next year, will be located \u201calong the tributary at Osprey Boulevard,\u201d McFadden said earlier.<\/p>\n The first and second pumping stations are located north along the creek at Cactus Gate and Smoke Tree and started operating in 2021 and 2025, respectively, she added.<\/p>\n Frustrated residents have pushed the City of Mississauga \u2014 in particular, the mayor \u2014 to have the fourth pumping station up and running by the end of 2026 instead of next year.<\/p>\n However, that won\u2019t happen, the city said last September.<\/p>\n A letter from the Lisgar Residents\u2019 Association to the mayor, council and senior city staff in September 2025 noted, in part, that \u201c\u2026 repeated flooding of Lisgar has caused serious financial hardship and deep anxiety in the community.<\/p>\n \u201cEvery year, the floods are becoming increasingly widespread as hundreds of homes are flooded, encompassing Lisgar from east to west, north to south. Lisgar has suffered repeated flooding, some (residents) as much as\u201d five and six flooding events, if not more.<\/p>\n $125 million in losses due to floods since 2008, residents say<\/p>\n The residents said last year they had also contacted, via letter, Canada\u2019s Finance Minister Fran\u00e7ois-Philippe Champagne and they had the support of Mississauga umbrella residents\u2019 group MIRANET (Mississauga Residents\u2019 Association Network) in pushing for the fourth station to be built faster.<\/p>\n In their late 2025 letter to the city, Lisgar residents said a timeline extending into 2027 \u201cis not acceptable to our community.\u201d<\/p>\n The letter continued, \u201cWe are respectfully requesting Mayor (Carolyn) Parrish to use the strong mayor powers to facilitate the construction of the remaining pumping stations\u201d so all are completed and running no later than the end of 2026.<\/p>\n Residents further noted that new homes being built in Lisgar and additional basement apartments being constructed \u201cwill put additional pressure on the stormwater sewer and sanitation sewer capacity that is currently overwhelming\u201d the system.<\/p>\n The residents\u2019 group estimated the total flood-related financial cost to residents, collectively, since 2008 to be around $125 million.<\/p>\n \u201cIt is bewildering after all these years to continue to experience flooding,\u201d the residents said in their letter.<\/p>\n Other measures to mitigate flooding<\/p>\n
