The Canadian Standards Association is an organization made up of various government agencies, power utilities, insurance companies, electrical manufacturers and other organizations. The CSA publishes CSA Standard C22.1 which is updated every two or three years. Each province adopts, with some amendments, this standard and publishes a province-specific code book. Since each province publishes its own slightly modified standard, it would be somewhat confusing to obtain the CSA standard itself. In this FAQ, "CEC" really means the appropriate provincial standard. In particular, this FAQ is derived from the Ontario Hydro Electrical Safety Code, 20th edition (1990). Which is in turn based on CSA C22.1-1990 (16th edition). While differences exist between the provinces, an attempt has been made to avoid specific-to-Ontario detail. The appropriate provincial code can be obtained from electrical inspection offices of your provincial power authority. In Ontario, it's Ontario Hydro. The Ontario Hydro book isn't overly fat. It's about C$25, and includes mailed updates. I hear that these standards are somewhat easier to read than the equivalent NEC publications. Don't bother asking in Quebec - DIY wiring is banned throughout the province.
