Why are so many panels running out of steam in Dollard-des-Ormeaux?
Dollard-des-Ormeaux is the city most concentrated in time in the whole West Island. Of its 17,380 private dwellings, the 2021 census counts 10,735 built between 1961 and 1980. Sixty-two percent of the city was built in twenty years.
No other city where we work is so compact: Brossard is at 35% for the same period, Laval at 33%. Here, almost all the housing is the same age.
That changes one concrete thing: the panels reach their limit at the same time. The bungalows and split-levels of DDO were all given a 100 amp panel when they were built. Half a century later, they have a heat pump, a finished basement, sometimes a pool — and more and more often an electric car in the driveway.
Which amperage for which house?
| Panel | What it supports | The sign it’s no longer enough |
|---|---|---|
| 60 A | A house built before 1960, oil or gas heating, no large appliances | No free space left, and an insurer asking questions at renewal |
| 100 A | A house from the 1960s to 1990s still as it was built | A breaker that trips when two appliances start together, or no room for a charger |
| 200 A | Today’s standard: electric heating, heat pump, EV charger | — |
| 320 to 400 A | Large house, or charger + heat pump + spa + workshop | — |
Fuses, breakers, and the panels to watch
In a DDO house, four situations come up again and again. The third is especially common here, precisely because of when the houses were built.
| What we see | What it means | What we do |
|---|---|---|
| 100 A panel with no free space | The most common case here. Nothing is broken, but nothing more can be added. | Upgrade to 200 A, often without touching the existing wiring. |
| Stacked double breakers | Two circuits in the space of one, to save room. A sign the panel is full. | We check whether the panel accepts them, then we calculate the real load. |
| Federal Pioneer Stab-Lok | Very common brand in houses built between 1970 and 1990. Breaker reliability disputed for decades. | Have it looked at before plugging anything else into it. |
| A breaker that trips often | The breaker isn’t the problem: it’s doing its job. The load is too high. | Load calculation, then an upgrade if it’s justified. |
How does it go, in practice?
One working day, including about five hours without power. That’s the real answer to the question everyone asks first.
We file the request with Hydro-Québec, which comes to disconnect the service. The old panel comes out, the new one goes in, every circuit is identified again one by one — that’s the longest part, and the one that will serve you for twenty years. Hydro-Québec reconnects, and the installation is tested before we leave.
In a house from the 1970s, the wiring is generally in good condition: we replace the panel, not the house. That’s what helps keep the bill down.
What does it cost in Dollard-des-Ormeaux?
The price depends on your installation, for example when the service entrance is redone at the same time: you get it in the written quote, free of charge. The real price depends on the target amperage, the condition of the service entrance and the mast, and the number of circuits to redo. A sub panel costs considerably less.
A photo of your open panel is often enough to tell you the next steps, without a visit.
Do you need a permit in Dollard-des-Ormeaux?
The City of Dollard-des-Ormeaux publishes no rule specifically about replacing an electrical panel. Its bylaw on permits and certificates lists the work that requires one — load-bearing walls, stairs, number of bedrooms, exits — and electricity isn’t listed as triggering a permit.
We won’t leave you guessing: we check with the City before we start, and we handle the forms, for the municipality as well as for Hydro-Québec. You have nothing to fill out.
Who is allowed to replace a panel in Québec?
The question comes up all the time, and the answer surprises people: it isn’t a matter of skill, it’s a matter of law.
“No one may perform electrical work of any kind, in their residence or elsewhere for others, unless they are an electrical contractor.” (translated from French)
“A person who contravenes the Master Electricians Act and the Building Act is liable to a fine of $5,000 to $200,888.” (translated from French)
Corporation des maîtres électriciens du Québec
In other words: even at home, even if you know how. STM Électrique inc. is a CMEQ member and holds RBQ licence 5815-0137-01.
Frequently asked questions
Can I replace my panel myself?
No. The Master Electricians Act forbids it, even in your own home, and the fine ranges from $5,000 to $200,888.
Do I need to notify Hydro-Québec?
Yes, and the electrician does it. The service request and the declaration of work go through Hydro-Québec’s professional portal, which only master electricians can access.
How long will I be without power?
About five hours over one working day. The rest goes to the connection and the testing.
My house was built in the 1970s. Is my panel at risk?
Not necessarily at risk, but often at its limit. That’s the period when the Federal Pioneer Stab-Lok brand was very common: if that’s the one you have, it’s worth a look before adding anything.
My neighbour just had theirs replaced. Is that a coincidence?
No. In a neighbourhood built in a few years, the panels reach their limit at about the same time. That’s why we often see several replacements on the same street a few months apart.
What we install. To replace a panel, we most often install a Siemens, a brand Adam Chirola considers reliable and high quality. Its breakers are easy to find across Québec: the day you need to add one for an EV charger, or replace one in ten years, it takes one visit, not a special order.
