In short
STM-Électrique and workplace chargers
STM-Électrique installs EV chargers for shops, offices and employee parking lots. It all starts with the building’s load calculation: it tells whether the installation is enough as is, with load management, or whether more capacity is needed. The quote for a commercial project usually arrives within 7 days. On the funding side, Écorecharge reimburses a business 50% of eligible expenses, up to $500,000 per site and per business (Québec page updated on September 16, 2026).
A charger for your customers or your employees
For a shop’s customers or an office’s employees: Adam Chirola, our master electrician, has confirmed that we install EV chargers for businesses. We already install Level 2 chargers in garages and outdoor parking areas.
For homes, EV chargers and panels are the jobs Adam Chirola has done most often in the region’s cities.
For an apartment building, it’s a different subject: see our page on EV chargers in apartment buildings.
What the building’s panel or service must supply
Before proposing a charger, we do the load calculation. There are three possible outcomes: the installation works as is, it works with a load management controller, or capacity has to be increased.
In a business building, Hydro-Québec supplies low voltage at 120/240 V single-phase or 347/600 V three-phase. When more capacity is needed, it’s the master electrician who files the service request with Hydro-Québec, then the declaration of work.
To place your building: most businesses fall under Hydro-Québec’s Rate G, which covers business customers whose minimum billing demand stays under 65 kW, about 90% of them.
Above 200 A at 347/600 V, or 320 A at 120/240 V, metering goes through transformers, and Hydro-Québec does the reconnection: the shutdown date is set with them. The details: service entrance and switchgear.
How many chargers, how much power
The answer comes from the same load calculation: it sets what the building’s service can give the chargers, and the actual current of each one.
A Level 2 charger is connected to a dedicated circuit, at 208 or 240 volts. Power is volts multiplied by amps: an ordinary outlet supplies 120 volts at about a dozen amps, a Level 2 charger 240 volts at 40 amps, or roughly five to six times more. For this category, Écorecharge’s business funding is capped at twice the charger’s purchase cost.
When capacity is tight, a load management controller can avoid increasing capacity: it’s one of the three outcomes of the calculation. To understand charging levels, see our guide to Level 1, 2 and 3 chargers.
Funding available to businesses
Read on November 3, 2026; a program can change: check its page before any purchase.
- Écorecharge, chargers in a business or an organization (Québec, page updated on September 16, 2026): 50% of eligible expenses, that is, buying and installing the chargers and the electrical infrastructure, up to $500,000 per site and per business.
- The electrical infrastructure must be installed by an electrical contractor; purchases and work must be made after January 1, 2024, and expenses from February 1 to March 31, 2025 are excluded for Level 2.
- The business and organization component (component 3, sub-component 3B: electrical infrastructure and chargers) ends on March 31, 2028, according to the program’s regulatory framework.
- Federal: the last call of the Zero Emission Vehicle Infrastructure Program (public charging along corridors, open from November 25, 2025 to March 20, 2026) closed on March 20, 2026, and no open call for a workplace charger was found.
- Hydro-Québec: its 2021 grant for the 4,500 standard Circuit électrique chargers was for municipalities only, with applications due by August 31, 2021; no Hydro-Québec funding for a business charger was found.
For a home, the funding is different, since it covers the charger’s price only: see the Québec EV charger rebate.
How the project goes
- A free written quote, usually within 7 days, with each item itemized.
- The building’s load calculation, before choosing the chargers.
- Hydro-Québec’s forms, when needed, filled out by us.
- A surprise along the way? We call you before going any further.
- Our work is covered for one year, parts and labour.
STM-Électrique is a firm of master electricians based in Mirabel, holding RBQ licence 5815-0137-01 and a member of the CMEQ: that’s the type of contractor Écorecharge requires for the electrical infrastructure. It isn’t just a program condition: Québec’s Construction Code reserves this work for an electrical contractor holding a licence from the Régie du bâtiment.
For comparison, for a home, our job includes the load calculation, the dedicated 240 V circuit, installing the charger, the municipal permit if the city requires one, the declaration of work to the Régie du bâtiment du Québec and a test with your vehicle.
We work in Montréal, Laval, the North Shore and the South Shore; our warehouse is in Laval and our offices are in Mirabel. Your city isn’t on the list? Leave your contact details and the team will confirm whether a visit is possible.

Commercial EV chargers: your questions
How much does an EV charger for a business cost?
We don’t publish prices for a commercial project: the price is in the quote, written and free of charge, which usually arrives within 7 days. On the funding side, Écorecharge reimburses a business 50% of eligible expenses, purchase and installation included, up to $500,000 per site (Québec page updated on September 16, 2026).
Is there a grant for a workplace charger?
Yes: Écorecharge’s business component pays 50% of eligible expenses, up to $500,000 per site, with a cap at twice the charger’s cost for Level 2. It requires an electrical contractor and work done after January 1, 2024; the component ends on March 31, 2028 (read on November 3, 2026).
Is our panel enough for several chargers in the parking lot?
The load calculation tells, and we do it before proposing a charger. There are three possible outcomes: the installation works as is, it works with a load management controller, or capacity has to be increased. The same calculation sets the actual current of each charger.
Who deals with Hydro-Québec?
We do. The master electrician files the service request with Hydro-Québec, then the declaration of work, and we fill out all the forms needed. If the building has transformer-rated metering, Hydro-Québec does the reconnection, and the shutdown date is set with them.
Do you install chargers in an outdoor parking lot?
Yes. We install Level 2 chargers in garages and outdoor parking areas. We start by measuring what the building’s service can still deliver: enough, and a dedicated circuit to each charger does the job; not enough, and we present the options to you in writing, in a quote that itemizes every line.
