That legend and colouring does not make sense to me 70+% catholic red, 20% protestant blue so, couldn’t the shade area be done in either colour, and then you have the no religion one with similar opposite range.

I realize it says by largest religion but seems odd in some areas to have 20% as largest religion or non religion and the typical others altogether not making up enough to be 21%.

If that is true why is Alberta catering to the religious people.

I could not find who made the map.

If you do find them, ask why they hate colorblind people so much.
