- Normals: the Canadian Climate Normals, 1991–2020, at Ottawa (City) (the closest location with all twelve months of temperatures).
- Comparisons: every Canadian town and neighbourhood of 2,500 or more, each read from its own nearest location; city totals and reserves are left out.
- 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.
