So let’s add another data set to Canada’s data to give a better understanding of the percentage of population by Province/Territory whose majority electrical power generation is from green sources as our province and territory borders are quite large but many of them have low population as the majority of Canada’s population is in a concentrated area in Southern Ontario and Southern Quebec.

Canada total = 39,292,355 (100%)
Newfoundland and Labrador = 528,818 (1.35%)
Prince Edward Island = 172,707 (0.44%)
Nova Scotia = 1,030,953 (2.62%)
New Brunswick = 820,786 (2.09%)
Quebec = 8,751,352 (22.27%)
Ontario = 15,262,660 (38.84%)
Manitoba = 1,420,228 (3.61%)
Saskatchewan = 1,205,119 (3.07%)
Alberta = 4,601,314 (11.71%)
British Columbia = 5,368,266 (13.66%)
Yukon = 43,964 (0.11%)
Northwest Territories = 45,602 (0.12%)
Nunavut = 40,586 (0.10%)

So armed with this data we can see that only 5 Provinces/Territories majority of sources of electricity are not green and when we look at percentage of population those 5 account for only 17.63% of the entire Canadian population meaning 82.37% of Canadians majority source for electrical power generation come from green sources.

And this is backed by Stats Canada who reports Canada's electrical power generation by source and the last month published (Nov. 2022) saw only 18.61% of all electrical power generated came from combustible fuels, and that includes the "Other types of electricity generation" as I can't say for certain that the energy produced was green, so it is possible it is lower than 18.61%
