Canadians are preparing for Canada Day under a wave of severe weather, as federal and provincial authorities respond to dangerous heat in the east and flooding concerns in the west. The unusual combination of weather events has prompted emergency planning across several provinces, with officials encouraging residents to monitor local forecasts and follow public safety advice.

In Ontario and Quebec, temperatures are forecast to reach 34–37°C, with humidity making it feel close to 40°C in some areas. Environment Canada has issued heat warnings, while municipalities including Toronto have expanded cooling centres, extended public pool hours, and established additional drinking water stations to protect vulnerable residents during the holiday period.

Meanwhile, Western Canada is facing heavy rainfall and rising river levels. Floodwaters have stranded campers in parts of Alberta, while officials are also monitoring elevated flood risks in Saskatchewan and Manitoba. Smoke from ongoing wildfires in northern Saskatchewan continues to affect air quality in some regions, adding another challenge for emergency services.

Emergency management officials are urging Canadians to remain weather-aware throughout the holiday, particularly those attending outdoor events, festivals, and travel activities. The evolving conditions highlight the growing impact of extreme weather on communities across the country during one of Canada's busiest travel periods.
