Environment Canada designates some stations with data that is the Departure from Normals 1971-2000.
This animated gif is the subset of stations with “Normals” mapped. The size of the blue (colder than Normal) or red (warmer than Normal) is related to the magnitude.
As you can see the recent heat wave that is making headlines is like a red wave that engulfs most of Canada and then retreats back to the north and eastern Canada.
Update: See below for BC map of stations (Blue are the cold ones …)
The stations are the ones with “Departure from 1971-2000 Normals” data (the D column) from here:

You can download climate data from the UK Met here.
If you graph the difference between the median sunshine hours against the difference between the median maximum temperature (Tmax) you see sunshine on the rise and tmax on the rise.
Don’t forget to ask the AGW side whether climate variables other than CO2 have changed recently.
