At night, details pop out of the fog in a more efficient way than during the day, thanks to the lights.
Here, the horizontal visibility is 3000m, vertical visibility 200ft.
If the screenshots are still taken at CYYZ on runway 05, it is normal to see almost the end of the runway, which has a length of 3390 meters, or 11120 feet.
I think the visual effect is really well rendered.
