One of the ways in which Edmonton Transit generates revenue is through renting space on the buses to advertise for componies. So because they drive around the city they are in essence a travelling billboard.
This one was stopped at a Transit Centre and is advertising a company named Go Auto which is formed by a number of dealerships here in the city.
There are a number of buses in the fleet that have been used by different companies. I think they make looking at the buses alot more fun
