The CEC is a voluntary standard. It is made mandatory and given the force of law by each Province or Territory through the use of an Order-In-Council.
All jurisdictions use the CEC as the basis for their electrical safety inspections, but many also enact Regulations to amend or extend the CEC in areas where changes are thought to be desirable.
Also not to be overlooked are the numerous weasel clauses in the CEC generally in the form 'acceptable to the Authority having jurisdiction'. This gives Provincial or Municipal inspectors and inspection departments the power to make up rules as well.
