Severe Winter Storm to Hit Toronto and GTA on Sunday

Environment Canada has issued an orange winter storm warning for Sunday, predicting significant snowfall across Toronto and the Greater Toronto Area (GTA). Some regions could experience snowfall totals reaching 50 centimeters, particularly in the southern parts of Etobicoke and Mississauga, due to lake-enhanced snow from Lake Ontario.
Snow Accumulation and Weather Conditions
Other areas within the GTA can expect 20 to 40 centimeters of snow. During the storm’s peak, snowfall rates may reach 5 to 8 centimeters per hour. Wind gusts could hit 50 km/h, leading to hazardous conditions for drivers.
- Snowfall Total: Up to 50 cm in some areas
- Peak Snowfall Rates: 5 to 8 cm per hour
- Wind Gusts: Up to 50 km/h
Transportation Disruptions
The severe weather has already caused significant disruptions, including hundreds of canceled flights. Toronto Pearson International Airport reported over 560 flight cancellations by 3 p.m. on Sunday, affecting 61% of departing and 63% of arriving flights. Passengers are advised to check with airlines for the latest travel updates.
Transit Service Impact
Public transit is also facing challenges. The Toronto Transit Commission (TTC) reported no service on Line 6 Finch West LRT due to switch issues. Line 1 Yonge-University and Line 2 Bloor-Danforth are experiencing service disruptions as well.
City Closures and Community Services
The City of Toronto has closed all library branches and museums and canceled recreational programs. While community recreation centers remain open, some may face localized closures due to the worsening weather conditions.
Similar actions have been taken by the City of Mississauga, which declared a significant weather event. City Hall, municipal offices, and libraries will be closed, while community centers and arenas are also shut down. However, the Paramount Fine Foods Centre will remain open for a scheduled event.
- City of Hamilton: All municipal buildings closed
- City of Oshawa: All city facilities closed
Effects on Schools
The winter storm is likely to affect school operations on Monday. The Toronto Catholic District School Board announced that high school exams set for Monday will be rescheduled if schools are closed. The Toronto District School Board will provide updates by 6 a.m. Monday.
Looking Ahead
As the storm progresses, Toronto officials are urging residents to avoid all non-essential travel. With snow accumulation expected to worsen, Monday’s commute may become challenging if the snowfall continues into the early hours.
Staying informed about weather updates and service changes is vital as the situation develops throughout the day.
