- Normals: the 1991–2020 Canadian Climate Normals at Toronto (City), the closest ECCC location with twelve months of temperature normals.
- Other locations: a location missing months of precipitation or snow is filled from the nearest that has them all, never mixed month by month.
- Comparisons: a pool of Canadian towns and neighbourhoods of 2,500 or more, read alike; whole cities and reserves stay out of it.
- 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.
