Condo Insurance in Ontario — Unit Owner vs Corporation Coverage

I'll never forget the musty smell that hit me when I opened the electrical panel in that 1970s condo on Lakeshore Road last Tuesday. The moment I lifted the cover, I could see scorch marks around three of the breakers, and when I touched the panel door, it was noticeably warm. The buyer standing behind me asked if that was normal, and I had to bite my tongue to keep from saying what I really thought.

After fifteen years of inspecting condos across Oakville, I've learned that electrical issues in these older buildings aren't just about one unit. They're about a shared system that's been stressed, modified, and patched for decades. What I find most concerning is how many buyers focus on the granite countertops and updated bathrooms while completely ignoring the electrical infrastructure that keeps everything running.

That Lakeshore condo turned out to have aluminum wiring throughout. The previous owner had done some renovations but never addressed the fact that aluminum wiring from the 1970s expands and contracts differently than copper, creating loose connections over time. Those loose connections generate heat, and heat creates fire risk.

You'll find this same issue in countless condos built between 1965 and 1975 throughout Old Oakville and the Bronte area. Buyers always underestimate how expensive electrical upgrades can be in a condo setting. We're not talking about a detached house where you can easily run new circuits. In a condo, you're dealing with shared walls, concrete construction, and strict condo corporation rules about what work can be performed.

I quoted the buyer $12,350 to have the aluminum wiring replaced with copper throughout the unit. That didn't include the cost of patching and repainting walls, or dealing with the condo board approval process, which can take months.

Here's what surprises most people about condo electrical systems. The individual unit's electrical panel might look perfectly fine, but the real problems often exist in the building's main electrical room. I can't inspect those areas because they're typically locked and managed by the building superintendent, but I've seen situations where the entire building's electrical capacity is inadequate for modern demands.

Sound familiar? Every unit has been upgraded with modern appliances, additional lighting, home offices with multiple computers, and charging stations for electric vehicles. The building's original electrical design from 1978 never anticipated this kind of load.

In that Glen Abbey condo I inspected last month, the owner complained about frequent power outages in their unit. During my inspection, I found that someone had installed a hot tub on the balcony and connected it to the kitchen circuit. The circuit breaker was constantly tripping because it was overloaded. The cost to install a dedicated 240-volt circuit for that hot tub would have been $3,800, but the damage to the electrical panel from repeated overloading meant they needed a complete panel replacement at $6,200.

What I find most frustrating is when I see DIY electrical work in condos. Last week on Speers Road, I found extension cords running through walls to power under-cabinet lighting. The previous owner had drilled holes through the drywall and fed regular household extension cords through the walls to avoid hiring an electrician.

This isn't just a code violation, it's a fire waiting to happen. Extension cords aren't designed for permanent installation, and they certainly aren't designed to be hidden inside walls where heat can build up. The cost to do that lighting installation properly would have been $1,850, but now the new owner faces $4,300 in remedial work to remove the dangerous wiring and install proper circuits.

Guess what we found when we opened up that wall? The extension cord had been spliced twice using electrical tape. No junction boxes, no proper wire nuts, just electrical tape wrapped around twisted wires inside the wall cavity.

GFCI protection is another issue I see constantly in 1980s and 1990s condos. The original electrical installation might have met code at the time, but current safety standards require GFCI outlets in bathrooms, kitchens, and any outdoor areas. I've inspected condos where the bathroom outlets were installed in 1983 and never updated. Installing GFCI protection throughout a typical two-bedroom condo runs about $850, but it's money well spent for safety.

You'll also want to pay attention to the electrical capacity of your unit. Many condos from this era have 100-amp service, which was adequate in 1975 but feels cramped today. If you're planning to install central air conditioning, upgrade to electric cooking, or add an electric vehicle charger, you might need to upgrade to 200-amp service. In a condo, this means coordination with the building management and potential upgrades to the building's main electrical system.

The cost for upgrading from 100-amp to 200-amp service in a condo setting ranges from $8,900 to $15,400, depending on the complexity and whether building infrastructure needs upgrading. I always recommend buyers factor this into their purchase negotiations, especially if they're looking at units in buildings from the 1960s through early 1980s.

Spring weather like we're expecting in April 2026 often reveals electrical problems that have been hiding all winter. When people start using their air conditioning units again after months of storage, I get calls about circuit breakers tripping and outlets that stopped working. These issues didn't develop overnight, they've been building all winter.

After fifteen years of inspecting condos across Oakville, I can tell you that electrical problems only get worse with time, never better. If you're considering a condo purchase in one of these classic buildings, get a thorough electrical inspection and budget accordingly for upgrades.
