The Ontario Electrical Safety Code governs electrical installations specifically in Ontario. This code sets out the standards and regulations that ensure the safe installation and maintenance of electrical wiring and devices within the province. It is developed to address the unique conditions and requirements of Ontario's electrical systems, thereby providing guidelines that electricians and contractors must adhere to in order to protect life and property from electrical hazards.

The other codes mentioned focus on different areas: the CSA B149.1 pertains to natural gas and propane installations, ensuring safe practices related to these fuels. The National Building Code of Canada provides a broad framework for building construction, including structural integrity and safety but does not specialize in electrical installations. Lastly, the CSA Z662 deals specifically with pipeline systems and therefore does not apply to electrical work. Thus, understanding the context of each code is crucial for ensuring compliance and safety in respective fields.
