When it comes to home electrical systems, what you can't see can hurt you — or at the very least, cost you. In Ontario, the Electrical Safety Authority (ESA) enforces strict standards to protect homeowners from electrical hazards. But many homes still suffer from common code violations that not only pose safety risks but can also impact insurance and resale value.
Here are the top five electrical code violations found in Ontario homes — and how to avoid them by staying on the right side of the code.
1. DIY Electrical Work
Many homeowners are tempted to undertake electrical projects themselves to save on costs or to tackle a personal endeavor. However, there are crucial factors to consider:
Risks Involved
Safety Hazards: Handling electrical components can lead to severe risks, including the potential for electrical shocks and fires.
Legal Consequences: Conducting electrical work without proper authorization can result in fines and legal repercussions.
Insurance Issues: Homeowner's insurance may not cover damages arising from unauthorized work.
Best Practices
Consult a Professional: It's advisable to hire a licensed electrician for any complex electrical tasks.
Research Local Codes: Get familiar with local building codes and regulations concerning electrical work.
Prioritize Safety: If you decide to proceed with DIY, ensure you are equipped with the right tools and knowledge to do so safely.
How to avoid it: Always hire a licensed electrical contractor (LEC). They will file the necessary notifications with the ESA and ensure the work is up to code.
2. Overloaded Circuits
Plugging too many appliances into a single circuit can lead to overheating and fire. This is especially common in older homes that weren’t designed for today’s power-hungry devices.
How to avoid it: Have a licensed electrician assess your panel and circuits. In some cases, upgrading to a larger panel or redistributing circuits can solve the issue.
3. Improper or Missing Junction Boxes
Splicing wires outside of an approved junction box — or hiding connections behind drywall — is a serious violation. Junction boxes protect connections and help prevent electrical fires.
How to avoid it: Make sure all wire connections are made within approved boxes, and that the boxes are accessible (not hidden behind walls or ceilings). Always use box covers.
4. Grounding and Bonding Issues
Improper grounding and bonding can create shock hazards, especially in damp locations like basements or kitchens. ESA requires all systems to be properly grounded to dissipate stray voltage.
How to avoid it: Have an electrician inspect the grounding system — particularly during renovations or when upgrading older systems.
5. Using the Wrong Type of Wire or Breaker
Not all wires and breakers are created equal. Using the wrong type (like indoor wire outdoors, or the wrong amp rating on a breaker) can result in overheating or even equipment failure.
How to avoid it: Only use CSA-approved materials suitable for your specific application, and ensure the installation meets ESA guidelines.
Stay Safe, Stay Legal
Electrical code violations can have serious consequences — from denied insurance claims to real danger. The good news? They’re 100% preventable with the help of a licensed electrical contractor.
