As some of you may know, I did a project while in school(and continue to add to it) on full service transit coverage in various cities.
I finally got around to doing Calgary's, which turned out to be one of the most complex cities to map out, due to the vary confusing route structure.
Anyway I thought you might like to see the map.
All routes listed on the map operate until at least midnight, seven days a week.
It seems the north end for some reason gets a lot more late night coverage than the south. Please remember this is just an overview map.

If you want to see how Calgary compares to other Prairie cities, here are Edmonton and Winnipeg's full service maps.
