Why are so many panels running out of steam in Brossard?
Brossard was designed and built in one go, and the figures show it. Of its 35,885 private dwellings, the 2021 census counts 12,670 built between 1961 and 1980 — more than a third of the city — against only 1,495 from 1960 or earlier.
These bungalows and split-levels in sectors A to P were given a 100 amp panel when that was generous. Sixty years later, they have a heat pump, a finished basement, sometimes a heated pool, and the panel has never moved.
At the other end, 13,220 dwellings have been built since 2001, often condominiums. There, the issue isn’t the old panel: it’s the capacity available when several owners want an EV charger.
Brossard, a city of owners
Brossard was incorporated in 1958, and the Champlain Bridge opened in 1962. It was a borough of Longueuil from January 1, 2002, to January 1, 2006, then became a city again.
At the 2021 census, it had 91,525 residents, and about 70% of households owned their home. Of its 35,885 occupied dwellings, 13,920 are single-detached houses, and 3,160 dwellings were built from 2016 to 2021.
In a condominium, the panel of your unit belongs to you, and the building’s service panel is the responsibility of the association.
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 house in Brossard, four situations come up again and again.
| 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 | Common brand 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 bungalow from the 1960s or 1970s, we also look at the mast and the meter base while we’re there: they’re often the same age as the panel, and redoing them later would mean cutting the power a second time.
What does it cost in Brossard?
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 Brossard?
No. The City of Brossard lists electrical work among the steps that don’t require a permit, just like plumbing work or installing a heat pump.
The Hydro-Québec step remains, and it’s mandatory: we take care of it. You have no form 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.
I live in a condo. Who is responsible for the panel?
The panel of your unit belongs to you. The building’s service panel is the responsibility of the condominium association. For an EV charger, both are involved — we look at both before proposing a solution.
My panel is 60 years old but nothing trips. Is that a problem?
Not in itself. A panel has no expiry date. What matters is the brand, the space available and the house’s real load — not the age on the label.
How much does a panel replacement cost in Brossard?
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. No municipal permit to plan for: Brossard lists electrical work among the steps that don’t require one.
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.
