The Calgary International Airport is one of the most dynamic and ahead of its time airports in North America, (i.e. they throw money at all sorts of vague projects. For instance turning the airport into a shopping mall, or installing internet-connected terminals called ePorts all over the place.) They are currently expanding the airport to increase capacity, adding a new "finger".
The Calgary Airport Authority was a government run organization until 1992, when is was privatized. The CAA, as it calls itself internally (but never externally due to copyright problems with the Canadian Auto Association), is a very lax workplace. Despite this, work actually gets done, and profits are good.
