In both the US and Canada, there's an official national code (US:

for each state (or province), and municipality.

P.S. Knight, on the other hand, publishes what is defacto
the official "electrician's training manual" for Canada, with
different versions for each provincial code, and is updated
in full synchronization with the code revisions. The DIY book
I'm recommending is similar - each province has a different version,
and it's updated in sync with the corresponding official code.


In Canada can code modifications only be made at the province level (not
city)? That would make life easier.
