Would it change anyone's opinion about the seriousness of the problem, if someone hacked into the control stations of Canada's electric power grid and overloaded the major transformers so that they burn out?  How would it be to live without electricity for a couple of years?  (The time it takes to manufacture and install replacement major transfomer equipment.  Most electric utilities in Canada only have a few pieces of reserve equipment for limited emergency situations).  Or how about if hackers shut down electronic banking and electronic funds transfer?  Maybe use bicycle couriers to transfer little pieces of paper between financial institutions, for example: I.O.U.  fify million dollars today ?
