The regulation of dams and dam safety falls under the responsibility of the provincial/territorial government. Canada is unique from other countries in the fact that no federal agency or over-arching program which guides the development of requirements for the safe management of dams. In the 1980’s the Canadian Dam Association was formed to provide dam owners, operators, consultants, suppliers and government agency with a national forum to discuss issues of dam safety[1]. It is evident that in high or moderate seismicity areas the design of tailings dams must take potential seismic activity into consideration. Many failures have occurred due to a lack of concern with respect to seismic hazard. Most failures are strongly related to inertial and/or weakening instabilities of the dam slopes[2]
