Between a pile of melting snow and the rainfall this week, the City of Mississauga is bracing for potential flooding.<\/p>\n
“The winter we had this year, it was colder than last year, so the snow held more water,” said Ben Gallagher, the city’s manager of the office of emergency management.<\/p>\n
“That water ends up in our waterways,” he said.<\/p>\n
Mississauga is home to many bodies of water, including rivers, lakes, stormwater ponds and Lake Ontario, which increases flooding \u2014 especially this time of year. <\/p>\n
Early spring brings a mix of rapid snowmelt, heavy rain and breaking ice. All of which can cause water to build up faster than the ground and the city’s drainage systems can handle. <\/p>\n
“One of the main things we want to get across to residents is to avoid putting yourself in any dangerous situations in the first place, really avoid any activity near the waterways,” Gallagher said.<\/p>\n

As temperatures rise in the GTA, so do flooding concerns<\/p>\n
Environment Canada says milder temperatures are expected all week in the GTA, raising the risk of flooding. As CBC’s Tyler Cheese explains, one neighbourhood is especially concerned.Lessons learned from 2024 flooding<\/p>\n
The city has learned a lot of lessons from torrential rainfall nearly two years ago<\/a> that caused massive flooding, road closures and power outages.<\/p>\n On July 16, 2024, and then, a month later, on Aug. 17 and 18, two record-breaking storms unleashed 280 millimetres of rain on Mississauga, trapping people on flooded roads, running over the edges of creeks, and soaking into buildings. The larger\u00a0Greater Toronto and Hamilton Area was also affected.<\/a>\u00a0 <\/p>\n WATCH | From 2024, in the wake of massive flooding: How floods are affecting Mississauga\u2019s stormwater system<\/p>\n Mississauga is still cleaning up after record rainfall flooded several parts of the city on the weekend. As Dale Manucdoc reports, the city\u2019s stormwater system is only designed to handle a weather event like that once every 10 years.<\/p>\n Last year, city council approved an action plan to ensure Mississauga’s stormwater system can continue to manage intense rain, ensuring the city is prepared for climate change-fuelled storms by pouring money into storm-water infrastructure upgrades.\u00a0 <\/p>\n![\"\"](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/03\/1773486309_182_default.jpg\")
