Annual temperature trend, 1948 to 2016, Summer temperature trend, 1948 to 2016, Winter temperature trend, 1948 to 2017 and Forest area, 2006, calculated using degrees Celsius and square kilometres units of measure (appearing as column headers).

Notes: The long-term temperature trend refers to the linear trend in temperature departures from the 1961 to 1990 climate normal over the period of 1948 to 2017. Positive values indicate that temperatures have warmed. Data for forest area are available from the National Forest Inventory by ecozone and have been adjusted to provide climate region totals. Excludes non-inventoried land in the Arctic ecozones (Arctic Cordillera, Northern Arctic, Southern Arctic) and small areas of the Taiga Plains and Hudson Plains ecozones located in Nunavut—areas that are largely devoid of tree cover.
