Daily observed weather for 18 Canadian metro stations (Toronto, Montreal, Vancouver, Calgary, Ottawa, Edmonton, Winnipeg, Quebec City, Hamilton, Kitchener, London, Victoria, Halifax, Saskatoon, Regina, St. John's, Kelowna, Moncton) from ECCC climate-daily observations (MSC GeoMet OGC API, keyless). Trailing 370 days, updated daily: max/min temperature (degC), precipitation (mm), snowfall and snow depth (cm), heating/cooling degree days (base 18 degC, ECCC published) plus ML-ready flags — heatwave (tmax>=32), deep freeze (tmin<=-15), heavy precipitation (>=25mm). ECCC 'M' (missing) flags become NULL, never imputed.

Trailing 370 days, updated daily: max/min temperature (degC), precipitation (mm), snowfall and snow depth (cm), heating/cooling degree days (base 18 degC, computed from the daily mean) plus ML-ready flags — heatwave (tmax>=32), deep freeze (tmin<=-15), heavy precipitation (>=25mm). GHCN -9999 (missing) becomes NULL, never imputed.
