Trend of Mean Temperature for 1948-2016 based on Canadian gridded data is an open dataset from Environment and Climate Change Canada with 9 files (HTML, PDF); catalogue record updated 2026-09-01. On CanQuery you can follow the original downloads. Files are available in English and French.

Seasonal and annual trends of mean surface air temperature change (degrees Celsius) for 1948-2016 based on Canadian gridded data (CANGRD) are available at a 50km resolution across Canada. Temperature trends represent the departure from a mean reference period (1961-1990). CANGRD data are interpolated from adjusted and homogenized climate station data (i.e., AHCCD datasets). Homogenized climate data incorporate adjustments to the original station data to account for discontinuities from non-climatic factors, such as instrument changes or station relocation.
