Power Outage on Quebec's North Shore and Laurentians: What Happened Last Week and How to Never Go Through It Again

Last week, the North Shore and the Laurentians reminded thousands of homeowners of an uncomfortable truth: the electrical grid is vulnerable, and when it fails, it always fails at the worst possible moment.

What started as a light accumulation of ice became something far more serious when the wind picked up. Uprooted trees, power lines down, and suddenly Terrebonne, Mascouche, Blainville, Mirabel, Saint-Jérôme, Repentigny, Saint-Lin-Laurentides, and Laval went dark. For some, a few hours. For others, several days.

My phone started ringing.

Last week I was on the road myself. A service call in Saint-Sauveur, up in the Laurentians — electrical problems caused directly by the storm. Driving north, I saw the damage firsthand: branches on the lines, entire zones still without power, homeowners waiting. The Laurentians are not a region that gets spared from this kind of event. They're a region where lines run through dense forest, where the trees are tall and the wind has no obstacles. When a storm hits, Saint-Sauveur, Sainte-Agathe, the cottages and permanent residences of the Laurentians are among the first to lose power — and among the last to get it back.

Clients wondering what to do. Homeowners realizing their electrically-heated houses were becoming unlivable. Families with young children or elderly parents suddenly without heat, without refrigeration, without light — in March, when the nights are still cold.

I'm an electrician on the North Shore and in the Laurentians. I've seen this scenario repeat itself. And every time, the same questions come back. Here's what you need to know — and what you can do to make sure it never happens again.

What To Do During a Power Outage

If you find yourself without electricity, here are the first steps to take in order.

In the first 30 minutes

Check the Hydro-Québec outage map to see if your sector is listed and to get an estimated restoration time. Unplug sensitive electronics — computers, televisions, audio equipment — to protect them from a power surge when electricity returns. Keep the refrigerator and freezer closed. A well-stocked refrigerator holds its temperature for about 4 hours. A full freezer can last 48 hours.

Find your flashlights, candles, and blankets before dark. Don't look for these things in the dark.

If the outage lasts several hours

Food safety becomes a priority. After 4 hours without power, refrigerated food enters a risk zone. When in doubt, throw it out. Food poisoning costs more than a grocery run.

In winter or in March on the North Shore, heating is critical. If your home is heated electrically and the outage lasts more than a few hours, start thinking about a backup plan — a neighbor's place, a hotel, family. Modern well-insulated homes hold their temperature reasonably well for a few hours, but with overnight temperatures still cool, things get cold fast.

If you have medical equipment that depends on electricity — CPAP, oxygen concentrator, infusion pump — you should have an emergency plan in place before an outage happens, not during one.

If the outage lasts more than 24 hours

This is where the situation becomes serious. Last week, some sectors of Mirabel, Saint-Lin-Laurentides, and the Laurentians were without power for several days. At this level you're no longer dealing with discomfort — you're dealing with a situation that affects your safety, your health, and your property.

The sump pump stops. Water in the pipes starts to risk freezing if heating is cut long enough. Food is lost. And the return of power can cause surges that damage appliances left plugged in.

Why the North Shore and Laurentians Are Particularly Vulnerable

It's not a coincidence that the North Shore and Laurentians regularly experience longer and more widespread outages than dense urban areas.

Geography works against us. Between Terrebonne, Mascouche, Mirabel, Saint-Lin-Laurentides, and Laurentian municipalities like Saint-Sauveur and Sainte-Agathe, a large portion of power lines runs through forested zones. When the wind picks up or ice accumulates on branches, trees fall on lines. Hydro-Québec must send crews to identify and repair each affected segment — in areas that are sometimes difficult to access, often in difficult weather conditions.

This is structurally different from an outage in central Laval where lines are often buried or run through clear corridors. On the North Shore and in the Laurentians, a single storm can affect dozens of sectors simultaneously, and repair crews must prioritize. Some neighborhoods wait hours. Others wait days.

Last week proved it again. I witnessed it firsthand on the road between Terrebonne and Saint-Sauveur.

The Real Question: Why Wait for the Next Outage?

Every time there's a storm on the North Shore or in the Laurentians, I get calls. Not just during the outage — during and after. People who spent two days without power calling to ask how much a generator costs. Homeowners who last fall said "we'll think about it" calling back now with more urgency.

I understand the logic. A backup generator represents an investment. Until the outage happens, it stays abstract. But once you've lived through several days without heat, without refrigeration, without being able to work from home — the calculation changes.

A residential automatic generator is not a luxury on the North Shore or in the Laurentians. It's basic infrastructure, in the same category as a heating system or a sump pump.

How a Residential Automatic Generator Works

Unlike a portable generator that you have to pull out of the garage, connect manually, and fuel with gasoline, an automatic generator — also called a standby generator — is permanently installed outside your home.

It connects directly to your electrical panel via an automatic transfer switch. As soon as it detects a power outage, it starts within seconds — whether you're home, at work, or away on vacation. Your home continues to function normally. You might not even notice if you're sleeping.

The most common residential models run on natural gas or propane. They require no manual intervention and test themselves automatically every week to make sure they're ready.

The two dominant brands in Quebec are Generac and Kohler. Both are reliable and suited to the Quebec climate. Generac is generally more accessible in terms of price and parts availability. Kohler is recognized for lower noise levels, which can matter if your generator will be close to a bedroom window or a neighbor's property. During a consultation, I evaluate your specific situation and recommend what actually fits your needs — not what costs the most.

What Installation Involves

Installing a residential automatic generator is not a project you improvise. Here's what it concretely involves.

Electrical load assessment

Before choosing the size of your generator, a master electrician must calculate your home's electrical load — which circuits you want to protect, what power that represents. Undersizing a generator means it will trip under load or run continuously at full capacity, shortening its lifespan significantly. This calculation is not something to estimate on your own using an online tool.

Site selection

The generator must respect minimum distances from windows, gas entry points, doors, and neighboring properties. It also needs to be accessible for maintenance. In certain municipalities on the North Shore and in the Laurentians, there are specific bylaws on distances and noise levels. I know the local requirements for Terrebonne, Mascouche, Blainville, Mirabel, Saint-Sauveur, and the other municipalities I serve.

Electrical permit

In Quebec, the installation of a residential automatic generator requires an electrical permit. Your licensed electrician handles this. With my CMEQ license and RBQ permit, I manage the entire regulatory process.

The concrete pad

The generator is installed on a poured concrete pad. Depending on the project, I coordinate this step or it's handled by a concrete contractor.

Electrical connections

The automatic transfer switch is installed at your electrical panel. The generator is wired. Everything is done to the Quebec Electrical Code.

Gas connection

A licensed plumber or gas fitter connects the generator to your natural gas line or propane tank. I coordinate this step with the necessary trades.

Commissioning

Once everything is in place, the generator is tested, programmed, and you receive a walkthrough on basic operation.

From the first consultation to full commissioning, a standard project typically takes 2 to 4 weeks depending on equipment availability and permit timelines.

What It Costs

I'd rather be direct than give you a range so wide it means nothing.

For a typical residential home on the North Shore or in the Laurentians, a fully installed Generac or Kohler automatic generator — equipment, labour, permits, concrete pad, and transfer switch — generally falls between $15,000 and $25,000 CAD depending on the size of the home, the complexity of the installation, and the model chosen.

That's an investment. It's also the price of never again spending several days without heat, without refrigeration, and without being able to function normally — regardless of what the weather does outside.

Last Week Could Have Been Different

The clients who called me during the outage — I couldn't install a generator for them in the middle of a storm. I was on the road to Saint-Sauveur for an emergency service call. But the ones who had called me last fall after the previous storm — they were ready. Their home kept running while their neighbors searched for candles.

The best time to install a generator is before the next outage. Not during. Not after.

If you're on the North Shore — Terrebonne, Mascouche, Blainville, Mirabel, Saint-Jérôme, Repentigny, Saint-Lin-Laurentides — or in the Laurentians — Saint-Sauveur, Sainte-Agathe, Mont-Tremblant — and you never want to go through what you experienced last week again, now is the right time to have a conversation.

No pressure. No sales pitch. Just an honest assessment of what would make sense for your home, from a master electrician who knows your territory.
