Annual grid point values were averaged together to produce an annual time series of temperature departures representing the entire country. Departures are calculated by subtracting the 1961 to 1990 reference value from the annual average. A positive departure indicates that the observed temperature was warmer than the reference value, while a negative departure indicates the opposite.",, Source: Environment and Climate Change Canada (2025) Canadian homogenized monthly surface air temperature (https://catalogue.ec.gc.ca/geonetwork/srv/eng/catalog.search#/metadata/542b90f7-ab39-452c-be5c-2afebdc4724c).,, Available on the Environmental indicators website (www.canada.ca/environmental-indicators).,,
