Niagara Region may declare a significant weather event when Environment Canada has issued a weather alert and we determine the hazard could pose a significant danger on the Regional road network. This can include conditions such as heavy snowfall or rainfall, freezing rain, blowing snow, poor visibility, extreme temperatures or severe thunderstorms.
The declaration is made under Ontario Regulation 239/02, Minimum Maintenance Standards for Municipal Highways, which defines a significant weather event as an approaching or occurring weather hazard with the potential to pose significant danger to highway users, and permits municipalities to communicate declarations through their website, social media or other methods.
