The Toiture & Isolation Provinciale team · Updated
LogisVert is Hydro-Québec's program that pays a grant, by cheque and after the work, for seven energy efficiency measures at home. For the attic, it is $1,500 when the whole roof surface reaches R-50 and the house is caulked, eight items included. The measure is for the owner of a house heated mainly with electricity, once per house. You apply online within nine months, and the cheque arrives 10 to 12 weeks after a complete application.

What is the LogisVert program?
Hydro-Québec created LogisVert to subsidize energy efficiency measures in Quebec homes. In English, Hydro-Québec calls it the LogisVert Efficient Homes Program. Individuals go through the residential stream. You have the work done or the equipment installed, you pay the invoice, then you apply online, and Hydro-Québec mails you a cheque. The residential stream has seven measures in 2026.
| Measure | Grant | Dwellings | Good to know |
|---|---|---|---|
| Roof insulation and caulking | $1,500 | House, if its owner heats it mainly with electricity | Both jobs are required, once per house. Details below |
| Central or wall-mounted heat pump | $50 per 1,000 BTU/h at −8 °C, or $120 for a cold-climate model | All, for their owner | ENERGY STAR certified since November 26, 2025, outdoor unit of at least 12,000 BTU/h |
| Geothermal heat pump replacement | $250 per 1,000 BTU/h, up to $18,000 for a house | House, plex, building of 19 units or fewer | The old unit must be at the end of its life and out of warranty |
| Induction range | $250 | All, tenants included | One per address, induction cooktops do not count |
| Heat pump dryer | $250 | All, tenants included | Ventless, condensation dryers do not count |
| Efficient pool pump | $125 (two-speed) or $300 (variable speed) | House, building of 19 units or fewer | Purchased and installed before November 30, 2026, application by March 1, 2027 |
| Solar panels | $1,000 per installed kilowatt, up to 40% of the cost | House, plex, building of 19 units or fewer | Installed since June 30, 2025, connection authorized by Hydro-Québec, batteries excluded |
| Multiple measures bonus | 5% more on the total | All | At least two different measures in a single application |
The grant never exceeds the purchase and installation cost before taxes, or 40% of that cost for solar. A “Multi-unit” bonus also applies to some wall-mounted heat pumps in rental buildings located in energy poverty areas. We do not install heat pumps, appliances, pool equipment or solar panels. Their full conditions are on Hydro-Québec's LogisVert page, and the calculation tool on the logisvert.ca portal estimates your amount before you buy.
LogisVert participant's guide, version 1.10, section 2.3 and appendices I and II.
The program's other streams
Under the “Installation company” stream, some central heating systems, such as a heat storage unit or a geothermal heat pump, are subsidized directly on the installer's invoice, with nothing for you to file. Another stream covers companies that build new homes, another covers housing offices, and the low-income households stream provides a free wall-mounted heat pump; its registrations for 2026-2027 are closed.
What LogisVert does not pay for
The residential stream pays for no new windows or doors, no walls, foundations or basements, and no water heaters, thermostats or batteries. Roof replacement, decontamination and vermiculite removal are not on the list either. Walls, foundations and windows fall under Rénoclimat, the Quebec government's program. For the basement, see our page on spray foam; for a contaminated attic, our decontamination service.
How much does LogisVert pay to insulate an attic?
LogisVert pays a fixed $1,500 when both the roof insulation and the caulking of the house are done and every program requirement is met. The amount depends neither on the size of the attic nor on the insulation already in place. If one of the two jobs is missing, the measure pays nothing. Roof insulation alone or caulking alone does not qualify.
Two rules frame that amount. The grant cannot exceed the cost of the work before taxes. And it goes up by 5% when a single application groups at least two different measures, such as roof insulation and a heat pump, carried out within nine months. In Hydro-Québec's example, a 5% bonus on a $1,000 grant brings the payment to $1,050.
Guide v1.10, sections 2.3, 2.4.1 and 2.7, appendix I (p. 11); FAQ of the logisvert.ca portal.
What conditions must the house and the work meet?
All the conditions below apply together. They come from appendix I of the participant's guide, which prevails, and from the measure's page on Hydro-Québec's website.
| Condition | What Hydro-Québec says | Where it is written |
|---|---|---|
| The applicant | “Owner of an eligible home” | Measure page |
| The house | “House (single-family, semi-detached, row house, mobile home, four-season cottage)” | Guide, appendix I |
| The heating | A house “that uses electricity as the main heating source” | Guide, appendix I |
| Only once | “This measure can only be implemented once in each home” | Guide, appendix I |
| The roof | “An RSI of at least 8.8 (R 50)”, with “100% of the surface of the roof” insulated | Guide, appendix I |
| The caulking | “All areas where air leaks” and eight items, “whether or not air leaks have been detected” | Guide, appendix I |
| The materials | “Materials that do not pose a health hazard” | Guide, appendix I |
| The company | Listed on the Registraire des entreprises du Québec, with an RBQ licence including subclass 7.0 (insulating, waterproofing, roofing and siding) | Guide, appendix I; measure page |
| The deadline | Application “no later than nine (9) months following the date at which the measure is implemented” | Guide, section 2.5 |
Quotes from the English version of the guide (version 1.10) and of Hydro-Québec's page. The French version is the original.
The house
The measure is for the owner of a single-family, semi-detached, row or mobile home, or a cottage. A row house held in co-ownership counts as a house. The portal's FAQ makes it eligible for every measure meant for house owners. The house must be in Quebec, completed, habitable year-round and heated mainly with electricity, whether it is supplied by Hydro-Québec or by a municipal, cooperative or off-grid system. A garage, shed or outbuilding that is not permanently attached to the house is not part of it.
A roof at R-50 over its whole surface
After the work, the roof must have a thermal resistance of at least R-50 (RSI 8.8), and 100% of its surface must be insulated, with fibreglass or an equivalent insulation. The guide makes no exception for a cathedral ceiling, a flat roof or an addition. Every part of the roof must reach the value. R-50 is also the value we aim for in every attic we insulate, and the one that must then appear on the invoice.
Eight items to caulk, even if they don't leak
The caulking must cover every spot in the house that lets air through, plus eight items named by Hydro-Québec, whether or not they leak.
| Item | Where to find it in the house |
|---|---|
| Windows | Around each window, from the basement to the top floor |
| Exterior doors | The front door, the back door, the side door |
| Patio doors | The patio door that opens onto the yard or the balcony |
| Attic hatches | The ceiling opening that leads to the attic, often in a closet or a hallway |
| Range hoods | The kitchen hood and its vent to the outside |
| Bathroom fans | The ceiling or wall fan in each bathroom |
| Electrical outlets | The outlets on the walls of the house |
| Fireplaces | The fireplace and its surround, if there is one |
Installing new windows or doors does not count as caulking. According to Hydro-Québec, air and ventilation leaks can account for up to 25% of a home's heat loss (LogisVert page). Warm air escaping into the attic also carries moisture up there, which is the subject of our article on attic condensation.
Guide v1.10, appendix I, p. 10; measure page on logisvert.ca.
An RBQ-licensed company, subclass 7.0
Both jobs must be done by a company registered with the Registraire des entreprises du Québec, holding a Régie du bâtiment du Québec licence with subclass 7.0 (insulating, waterproofing, roofing and siding). If two companies share the insulation and the caulking, the application gives each one's licence number. Hydro-Québec recommends checking the licence in the RBQ registry. Ours, 5839-3208-01, is active, includes that subclass and appears on every invoice.
The guide provides for no registration of companies with the program for this measure, and Hydro-Québec says it works with no company other than its service provider. A company that calls itself “registered with the program” or a Hydro-Québec “partner” gives you a reason to ask questions.
What rules the measure out
The measure does not apply to a tenant, who is eligible only for the induction range and the dryer, or to a condominium apartment, a duplex, a triplex or an apartment building. It also excludes a house heated mainly with gas, oil, propane or wood, a detached building such as a garage, and a house that has already received it.
Does your house meet the conditions?
The checker turns the official conditions into eight questions. It tells you whether something rules the measure out, what remains to be confirmed and, if the work is done, your deadline. It does not replace Hydro-Québec's decision, which is made on a complete application.
The LogisVert checker, roof insulation and caulking
Eight questions based on the official conditions. The last one is optional.
Your answers stay in your browser. Nothing is sent.
How do you put together a complete LogisVert file?
Hydro-Québec decides on the documents. A complete file comes down to three things: invoices that carry every required detail, a proof of ownership, and a participant profile in your name on the logisvert.ca portal.
What the invoices must show
The guide lists the details for each of the two jobs, and they are almost the same. Only the description of what was done differs.
| Detail | Roof insulation | Caulking |
|---|---|---|
| Invoice number and date | Required | Required |
| Installation date | Required | Required |
| Your name | Required | Required |
| Address of the work | Required | Required |
| Company name | Required | Required |
| Company's RBQ licence number | Required | Required |
| Company's GST and QST numbers | Required | Required |
| What was done | Description of the work, insulation used and the roof's new thermal resistance, in R or RSI | Itemized list of the caulking work |
| Cost of the work | Required | Required |
| Proof of payment | Statement that the invoice is paid in full | Statement that the invoice is paid in full |
A purchase order or a contract is not an invoice, and the portal does not accept it as proof.
Guide v1.10, appendix I, p. 11, and section 3, step 1; logisvert.ca portal, measure page.
Documents and numbers to provide
- Proof of ownership: the municipal tax bill or the first page of the deed of sale, as an electronic copy. A member of an Indigenous community provides an electricity bill in their name or a letter from the band council instead.
- Your Hydro-Québec customer and meter numbers, printed on your electricity bill. The customer number has 9 digits and starts with 1. You do not have to attach the bill.
- The RBQ licence number of each company that did the work.
- The same first and last name everywhere: participant profile, invoices and proof of ownership. The grant is paid only to the owner.
- No photos. This measure's requirements ask for none, unlike those for appliances.

What we prepare, and what stays in your name
Before the work, we check the house's eligibility with you: the type of dwelling, the heating, the roof and any grant already received. If part of the roof cannot reach R-50, we tell you during the visit, before you sign. After the work, we hand you the invoices with every required detail, paid-in-full statement included, then we prepare the application on the portal and file it with you.
The participant profile stays in your name. You provide your tax bill or deed of sale, and your customer and meter numbers. If Hydro-Québec asks for your SIN, you give it to Hydro-Québec directly, through the secure channel it indicates, never by email. And if it asks for documents or a visit, it contacts you.
The end-of-work report in our Dossier Provincial, with before, during and after photos and measurements, is not required by Hydro-Québec. It is useful the day it asks for proof or comes to see the work. Since the cheque comes after the work, you can pay for the work with our financing (from $17/month, 3 months no payments and no interest, subject to credit approval).
A call or a visit on behalf of Hydro-Québec?
Hydro-Québec never does telephone or door-to-door solicitation for LogisVert, and works with no company other than its service provider, Groupe Marketing International. An offer you did not ask for, made in its name, is probably a fraud. We never speak on behalf of Hydro-Québec. If in doubt, call LogisVert Program Support at 1 833 396-1888.
How long does it take to apply and get the cheque?
You apply online no later than nine months after the measure is completed. An incomplete application is flagged within about 20 business days. Once the application is complete, allow 10 to 12 weeks of processing. Payment then comes by cheque, by mail, sent to the mailing address on the application.

Which mistakes get an application refused or delayed?
On the paperwork side, the guide and the portal name these situations, which lead to a refusal, a repayment or a delay.
- A name that changes from one document to the next. The first and last name on the profile, the invoices and the proof of ownership must be identical.
- A purchase order or a contract instead of an invoice. Neither is accepted as proof.
- An incomplete invoice, with no statement that it is paid in full, no new insulation value for the roof or no itemized list of the caulking.
- A missing or unreadable document. The portal warns that an application without every required document will be refused.
- An application sent by email or by mail. It is not processed, only the portal counts.
- More than nine months between the completion of the measure and the application.
- Only one of the two jobs, insulation without caulking or the reverse, or caulking limited to visible leaks.
- A company without subclass 7.0, or work you did yourself.
- A grant already received for the same work, from Rénoclimat or another agency. The grant would be refused, or clawed back if it was paid.

Row house, cottage, garage, dual energy: what do the sources say?
For each of these cases, here is what the official sources say, or don't. When they don't settle it, only LogisVert Program Support can confirm your case, at 1 833 396-1888.
| Situation | What the sources say | In practice |
|---|---|---|
| Row house held in co-ownership | The portal's FAQ makes it eligible for every measure meant for house owners. | Same conditions as a house. |
| Cottage | The guide accepts a “cottage-type” house if it is habitable year-round. | Eligible if it is habitable all year and heated mainly with electricity. |
| Detached garage, shed or outbuilding | A building not permanently attached to the house is not part of it, except for solar panels (guide, section 2.2). | No grant to insulate them. |
| Attached garage, addition, cathedral ceiling | The guide requires R-50 over 100% of the roof surface, without detailing these parts. | Plan for R-50 everywhere. For the roof of an attached garage, confirm at 1 833 396-1888 before the work. |
| Owner who does not live in the house | The portal's FAQ accepts the application, with the owner's customer number. The guide provides for an RL-27 slip for property that earns income. | Possible. Have your NEQ, QST number or SIN ready. |
| New house | The FAQ accepts it, with a purchase and installation invoice in your name; construction must be completed. | Same conditions as any other house. |
| Roof and caulking measure already received | Only once per dwelling (guide, appendix I). | No further grant for this measure, even after a purchase. |
| Old “very high efficiency heat pump and caulking” measure | Withdrawn on August 25, 2025. The portal's FAQ says only one measure that includes caulking can be carried out in a house. | Probably excluded, not certain. Confirm at 1 833 396-1888. |
| Dual energy | The guide requires electricity as the main heating source, without defining it. On its Rate DT page (in French), Hydro-Québec describes dual energy as electricity as the main source, with a backup fuel. | Likely, never stated for LogisVert. Confirm at 1 833 396-1888. |
| Tenant | Only the induction range and the heat pump dryer (guide, section 2.3). | The owner can apply for the roof measure. |
| Vermiculite in the attic | The guide requires materials that pose no health risk, and says nothing about vermiculite already in place. Removing it is not a program measure. | It is removed before insulating, outside the grant. See our decontamination page. |
LogisVert or Rénoclimat for the attic?
For a house heated mainly with electricity, both programs can pay for attic insulation, but never both for the same work. They do not ask for the same thing.
| Criterion | LogisVert | Rénoclimat, since October 1, 2026 |
|---|---|---|
| Grant for the attic | $1,500, fixed amount | $1.75 per sq ft, up to $2,000 for a house |
| Value to reach | R-50 over the whole roof | R-60 in the attic, with at least R-20 added, over 300 sq ft or more |
| Caulking | Required, included in the $1,500 | Neither required nor paid |
At $1.75 per square foot, Rénoclimat passes $1,500 beyond about 860 sq ft insulated. For a 1,000 sq ft attic brought to R-60, the calculation gives $1,750, without exceeding the cost of the work before taxes. Rénoclimat sets no heating condition and accepts duplexes and triplexes.
To combine the two on different work, for example the roof with LogisVert and spray foam on the foundation with Rénoclimat, the rule is not settled. LogisVert only rules out double funding for the same work, but the Rénoclimat guide bans in general terms any combination with aid from a Crown corporation such as Hydro-Québec. Have Rénoclimat confirm your case, at 1 866 266-0008, before you start.
The criterion-by-criterion comparison, with the steps for each program, is in our LogisVert or Rénoclimat for the attic guide.

What has changed in LogisVert since 2025?
Many pages about LogisVert still describe measures that no longer exist. The table follows the changes in order.
| Date | What changed |
|---|---|
| January 20, 2025 | The guide (version 1.3) already requires caulking of today's eight items, “whether or not they leak”. The 2023 list was different. |
| March 31, 2025 | The efficient pool pump replaces the former measure that included solar thermal collectors. |
| August 25, 2025 | The “very high efficiency heat pump and caulking” measure is withdrawn; geothermal heat pump replacement is added. |
| November 26, 2025 | Heat pumps must be ENERGY STAR certified. The guide specifies that new windows or doors do not count as caulking, and that a detached building is not part of the dwelling. |
| March 31, 2026 | Solar panels enter the guide. The Quebec government's Chauffez vert program, for oil and propane, ends the same day. |
| June 15, 2026 | “Multi-unit” bonus for some wall-mounted heat pumps. |
| September 15, 2026 | Version 1.10 of the guide, now in force: solar panels allowed on a detached building, announced end of the pool pump. |
| October 1, 2026 | Rénoclimat is rebuilt: optional energy assessment, attic brought to R-60, $1.75 per sq ft. |
| October 8, 2026 | The federal government announces heat pump grants starting in 2027, without details. LogisVert remains in force. |
| November 30, 2026 | End of the efficient pool pump; application by March 1, 2027. |
The amount for roof insulation and caulking, $1,500, has not changed since the first version of the guide, dated January 1, 2023. If an article gives you a different list of items to caulk, or a measure that no longer exists, check its date.
