Climate Trend Mapper (CTM) from the University of Winnipeg, is an interactive desktop application with which users can visualize temperature and precipitation trends across Canada using Environment Canada’s AHCCD data. This program makes it easy for users to visualize the climate data and trends recorded at weather stations across Canada. In particular, the program allows you to produce high-quality maps of the trends (or lack thereof) observed in the monthly, seasonal and annual temperature and precipitation data. For temperature, you can map the trends in the maximum, minimum and mean temperatures. For precipitation, you can map the trends for rain, snow and total precipitation. The mapper app is not served up as a WMS (strangely) but rather, is available as a download via http://climate.uwinnipeg.ca/
