Whole home surge protectors are not required by Canadian electrical codes or regulations. Electrical codes and regulations can vary by province and territory in Canada, and they may be subject to updates and changes over time.
In Canada, the installation of surge protection devices, including whole home surge protectors, is generally left to the discretion of homeowners and electrical professionals. However, it's important to note that while not required, whole-home surge protectors are strongly recommended as they can help safeguard your home's electrical system and valuable electronic devices from power surges, including those caused by lightning strikes, utility grid fluctuations, or other factors.
Since regulations and recommendations can change over time, it's advisable to check with your local electrical authority or a licensed electrician in your area to get the most up-to-date information regarding surge protection requirements or recommendations in your specific region. They can provide guidance on whether a whole home surge protector is advisable for your particular circumstances and can assist with the installation if needed.
