Quebec sits primarily in a humid continental and subarctic climate (Dfb/Dfc), with Montreal and the St. Lawrence valley seeing January averages around -10°C and Quebec City and the Laurentians running colder still. The province has 30 verified geothermal contractors in our directory, with concentrations in the Greater Montreal area, Quebec City, and the Outaouais region. Hydro-Québec's LogisVert program offers some of the largest residential geothermal rebates in Canada — up to $54,000 on a new installation — which, combined with low electricity rates from the Hydro-Québec network, makes Quebec a particularly compelling province for geothermal adoption.

Top Quebec cities for geothermal contractors
Contractor coverage in Quebec is strongest in the Montreal metropolitan area and the greater Quebec City region. The Montérégie and Estrie regions have growing installer activity as rural homeowners move off oil heat. The Outaouais (Gatineau area) has contractors who frequently work across the Ontario border.

Quebec geothermal incentives in 2026
Quebec has one active provincial geothermal rebate program — Hydro-Québec's LogisVert — and federal OHPA funding available for homeowners converting from oil. Note that Rénoclimat, which is still active as a home retrofit program, no longer provides any financial assistance for heating system installation or replacement, including geothermal. Homeowners searching for a "Rénoclimat géothermie" rebate should apply through LogisVert instead.
- LogisVert (Hydro-Québec) — Quebec's primary provincial geothermal rebate. For a new geothermal installation where geothermal is the primary heating source: $750 per 1,000 BTU/h of heating capacity, capped at $54,000 per address (72,000 BTU/h / roughly 6 tons). For a replacement of an existing geothermal system: $250 per 1,000 BTU/h, capped at $18,000 per address. As a reference point, a typical residential 3-ton (36,000 BTU/h) new installation calculates to approximately $27,000 in rebates under the current rates. Equipment must be new and purchased from Quebec retailers; installation must be by an RBQ-licensed contractor. Apply within 9 months of the installation date through logisvert.ca (French-language portal). See our Canadian incentives guide for a full breakdown.
- Oil to Heat Pump Affordability Program (OHPA) — Federal program for oil-heated homes with household income at or below the provincial median. Ground source heat pumps are explicitly eligible, provided the system meets the CSA C448 standard. Quebec is a federal-delivery province: eligible households can receive up to $10,000 federal. Eligible costs include the outdoor piping loops for a ground source system. LogisVert and OHPA can be stacked for oil-to-geothermal conversions — confirm stacking eligibility at the time of application. Apply through our Canadian incentives guide or directly through Natural Resources Canada.

Quebec geothermal regulations & well-drilling rules
Quebec's geothermal installations are governed by the Règlement sur le prélèvement des eaux et leur protection (RPEP), Q-2, r. 35.2, made under the Loi sur la qualité de l'environnement (LQE). Chapter IV of the RPEP (Articles 28–30) applies specifically to geothermal systems. The regulation is current to March 1, 2026.
Closed-loop systems (pompes à chaleur couplées au sol) are governed by RPEP Article 29. Key rules:
- Prohibited heat transfer fluids: ethylene glycol, potassium acetate, and methanol cannot be used in any new closed-loop system. Check with your installer on approved alternatives (typically food-grade propylene glycol or clean water where freeze protection allows).
- Underground components must be made of new materials.
- The system cannot be located on a shoreline, riverbank, or flood zone.
- Boreholes deeper than 5 metres must prevent water runoff from reaching system components (equivalent to water-supply well sealing standards).
Completion report (Article 30). Within 30 days of finishing work on any closed-loop geothermal system, the installer or supervising professional must send a written report to the Minister (MELCCFP) and a copy to the municipality. The report must include a localization plan showing underground components, the loop dimensions, the heat transfer fluid composition, and the results of pressure tests. This report is a public document.
Open-loop systems (pompes à chaleur d'aquifère, Article 28) must comply with RPEP Articles 12–26, which cover groundwater withdrawal standards: casing, grouting, and setback requirements from wastewater systems, composting areas, livestock facilities, and similar contamination sources. The RPEP mandates setback minimums including at least 15 metres from a sealed wastewater treatment system and 30 metres from an unsealed one.
Municipal authorization is the primary pre-installation checkpoint in Quebec. RPEP Chapter IV is enforced by municipalities, not the provincial ministry for standard residential and commercial installations. Obtain a municipal permit or declaration of conformity before breaking ground.
Wetlands and waterbodies. Boreholes in or near wetlands or waterbodies require a declaration of conformity under REAFIE Article 319, filed with MELCCFP, in addition to the municipal permit.
Unlike Ontario, Quebec does not require a provincial pre-approval (ECA equivalent) for standard residential closed-loop geothermal — the framework is declaration- and report-based. However, your driller must also hold the applicable RBQ licence subcategories for the mechanical installation (refrigeration, plumbing/hydronic, and electrical). The specific RBQ subcategory for the borehole drilling itself is not separately defined — contact the RBQ at 1-800-361-0761 to confirm which licence class applies to your project.

Quebec climate and ground conditions
The St. Lawrence Lowlands around Montreal (Dfb) have a cold winter but a warm summer, with ground temperatures at depth typically in the 7–9°C range. The region sits on a mix of Precambrian Shield to the north and sedimentary bedrock (limestone, shale) to the south and east. Vertical boreholes are the norm for residential lots in Montreal and Laval; horizontal loops are used on larger rural properties in the Montérégie and Estrie.
Quebec City and the Capitale-Nationale (Dfb/Dfc fringe) are colder, with longer heating seasons and annual heating degree days considerably higher than Montreal. This increases the annual output advantage of geothermal over oil or propane, which is relevant given that many rural Quebec homes in this region still heat with oil — making the LogisVert + OHPA combination particularly attractive.
The Laurentians and Lanaudière north of Montreal are hard Canadian Shield country — granite and gneiss at relatively shallow depths. Borehole costs here run higher than in the sedimentary south, but ground thermal conductivity is good, and the absence of natural gas service means electric resistance heat or propane is the alternative. Many cottages and year-round homes in this region are good geothermal candidates once the economics are modelled against propane costs.
The Outaouais (Gatineau/Hull area) has geology and climate similar to Ottawa: a mix of sedimentary and Shield formations, cold winters, and contractor access from both Quebec- and Ontario-licensed firms. Note that a Quebec-licensed contractor (RBQ licence) is required regardless of where the firm is headquartered.
Hydro-Québec's low residential electricity rates (among the lowest in North America) change the economics compared to other provinces: geothermal competes not against expensive grid power but against oil, propane, and wood, where the fuel-cost savings are largest. Homes currently on oil heat with an upcoming furnace replacement are the clearest cases for geothermal in Quebec.
