There was a program on the radio once I was driving a few month ago which they were discussing the tele-communication towers and their rapid growth around the city. Of course not their growth but grow in their numbers. People were complaining how ugly they are and how cellular phone companies go around the laws to be able to plant more in and around the city. According to a some sort of city by-law or any other jurisdictional regulations, communication towers should not be taller than X meters. So the companies started ordering theirs in X-.5 meter and planting them everywhere they needed! That actually is a very good example as how laws work in Canada. There are thousands of different regulations for everything but because there is always a way to get around it or alter it, most of them of broken. Rather than that there is not much enforcement so no one cares to follow.
(Photo: I found this tower in a small manufacturing facility and when I talked to the owner of the shop and asked him if he receives rent for that he confirmed and added that he wished they had put up more of this on his property!)
