Make sure you set aside some extra time to get to work on Wednesday morning, because Ontario is set to be hit with a massive rainstorm that will bring upwards of 50 millimeters of precipitation to some areas.
Environment and Climate Change Canada (ECCC) issued a special weather statement on Tuesday morning for Toronto, warning of significant rainfall that’s expected to hit mid-week from Wednesday morning through early Thursday morning.
According to The Weather Network, the historical average for rain in Toronto during the month of April is 93 millimeters, and some areas are expected to get at least half of that in one day.
Total rainfall amounts will range anywhere from 30 to 50 millimeters, with locally higher amounts possible in thunderstorms. According to ECCC, rain will begin Wednesday morning over extreme southwestern Ontario before reaching the Golden Horseshoe by Wednesday afternoon.
Another week, another low pressure system.
Special weather statements are in effect for much of the province for snowfall, freezing rain, and rain. A winter storm watch is in effect west of Lake Superior for significant snow.

Thunderstorms are also expected, and rainfall amounts might exceed 50 millimeters in some areas, particularly over southwestern Ontario. The rain will eventually end from west to east on Wednesday night into early Thursday morning.
The government department warns that localized flooding might be possible in low-lying areas, and additional rainfall warnings might be required for some areas as the event draws nearer.
Although Toronto was left unscathed by the ice storm this past weekend that left almost 400,000 Ontario residents without power, we won’t be immune to all of the precipitation that’s set to come down this April.
According to The Weather Network’s 2025 Spring Forecast, above-normal precipitation totals are expected in Ontario this season, especially throughout April, which could delay the start of the planting season.
The weather agency notes that the season is notorious for delivering a few final punches of winterlike weather, so while warmer days are certainly ahead, make sure to keep your rain boots and umbrellas close by for now.
