This picture proves nothing of the sort.
I was going to say that it shows a higher light density in Alberta than in Ontario, which is backwards.
I would suggest that the picture is more indicative of how close together the light sources are, two points close together not being resolvable.
Come all of you cowboys all over this land,
I'll teach you the law of the Ranger's Command:
To hold a six shooter, and never to run
As long as there's bullets in both of your guns.
