Where Legal’s numbers come from

Averages over 30 years, not a forecast.

Normals: the 1991–2020 Canadian Climate Normals at Fort Saskatchewan, the closest ECCC location with twelve months of temperature normals.
Comparisons: the 2,500-plus towns and neighbourhoods of Canada, each read from its closest normals location; whole cities and reserves aren’t counted.
Not on this page: sunshine (no 1991–2020 normals exist for it) and any altitude adjustment, since there is no elevation for the town itself.
