About WeatherCA
Founded to deliver high-resolution, uncompromised, and ad-clutter-free weather intelligence for Canadians. From sub-arctic diamond mines in the Northwest Territories to downtown financial towers in Toronto and Vancouver harbour, WeatherCA powers daily decisions with scientific precision.
HRDPS 2.5km Modeling
We compute hyper-local atmospheric forecasts utilizing the High-Resolution Deterministic Prediction System (HRDPS) from Environment Canada, providing true 2.5 km grid spacing across complex Canadian geography.
Official ECCC Alerts
Direct CAP (Common Alerting Protocol) telemetry with Environment and Climate Change Canada ensures immediate red-banner broadcasts for blizzards, freezing rain, tornadoes, and extreme cold statements.
5,000+ Communities
Full coverage of all 10 provinces and 3 northern territories, indexed by forward sortation areas (FSA postal codes), municipal jurisdictions, and Indigenous northern settlements.
Canadian Radar Modernization
WeatherCA ingests live dual-polarization imagery from all 31 modern S-Band radar towers across the national network (King City, Britt, Landrienne, McGill, Strathmore, Silver Star, Aldergrove, etc.). Dual-pol technology enables instant discrimination between wet snow, ice pellets, hail, and rain.
