the code books are so convaluted now im surprised any one can understand them.I have a red seal interprovincial but my test was written on the canadian code book,but i live in ontario and it has its own code book quebec has there's and so on, some cities have certain rules before you do electrical in their town. In my opinion there should be one code for the whole country period.I like the kiss method myself, but everyone has their opinion and this is mine!
