Colin asked;
"I'm currently doing research on the use of Information Security Classifications ..... in local government and to date have only found one municipality (City of Calgary in Ontario, Canada) that has adopted same. Perhaps you know of other examples? FYI, I'm just looking for examples in the municipal sector."
