Libraries and Wireless Internet Access

From what I can tell, many libraries in the US and even other Canadian cities have been implementing wireless Internet access for their patrons to use in the library. However, the Toronto area libraries (Toronto Public Library, Richmond Hill Public Library, Vaughan Public Library) seem to be moving slowly. From what I can tell, wireless Internet access is only available at a single VPL branch (The Pierre Berton branch in Woodbridge). I’m not sure why this is the case. Most branches offer public access computers that are connected to the Internet. Why not make it easier for students and other patrons that wish to use their own laptop while studying or doing research at the library.
