Newfoundland and Labrador is one of the colder parts of Canada, with heating-degree days that routinely exceed 5,000 in most communities. Oil heat is the dominant fuel source — nearly two-thirds of Newfoundland homes heat with oil — which makes geothermal a strong long-term option for homeowners who want to cut both fuel costs and price-volatility risk. Our directory lists 10 verified geothermal contractors serving St. John's, Corner Brook, Gander, and other communities across the island and Labrador. The province has no direct geothermal rebate, but oil-heated homes may qualify for federal financing support through the Oil to Heat Pump Affordability Program.

Top Newfoundland and Labrador cities for geothermal contractors
Most verified contractors are based in or near St. John's, with additional coverage on the Avalon Peninsula and in the Corner Brook area on the west coast. Remote communities in Labrador have limited local contractor availability; projects there typically involve contractors who travel for larger installations.

Newfoundland and Labrador geothermal incentives in 2026
NL has no provincial grant or rebate specifically for geothermal heat pumps. The province's main heat-pump incentive program (takeCHARGE) covers air-source heat pumps only — geothermal is not eligible under that program. The options for geothermal in NL are financing through Newfoundland Power and, for oil-heated homes, the federal OHPA program.
- Oil to Heat Pump Affordability Program (OHPA) — up to $15,000 for oil-heated homes. Federal program, co-delivered in Newfoundland and Labrador. Ground-source heat pumps are eligible (must meet CSA C448 standard). Your household income must be at or below the area median, and the home must currently be heated with oil. Where both federal and provincial co-delivery funds are available, the combined maximum is $15,000. Speak with a participating contractor to confirm current program status in your area. OHPA details →
- Newfoundland Power Heat Pump Financing. Newfoundland Power offers financing for ground-source heat pump installations to customers on their grid. This is a loan, not a grant — the current rate is 8.45% (reviewed quarterly). The amount available for geothermal is not published on the program page; contact Newfoundland Power at 1-800-663-2802 for terms. Eligible installers must hold a Journeyperson Refrigeration and Air Conditioning Mechanic certification and be a Registered Electrical Contractor. Financing options →
Note: The Canada Greener Homes Grant and Canada Greener Homes Loan are both closed to new applications. The takeCHARGE Oil to Electric program does not cover geothermal — it is limited to air-source heat pumps. Check our permits tool for the latest on available programs.
Newfoundland & Labrador geothermal regulations & well-drilling rules
NL has one of the more developed geothermal regulatory frameworks in Atlantic Canada. The foundation is the Water Resources Act, SNL 2002, c. W-4.01 and the Well Drilling Regulations, NLR 63/03, which require all well drilling to be done by a licensed water-well driller (licensed under s. 55 of the Water Resources Act). As of early 2026 there were 95 active licensed drillers in the province; there is no separate geothermal driller licence — all hold the same licence class.
In 2022, the province's Water Resources Management Division issued Guidelines for the Construction of Ground Sourced Heat Pump Systems — a non-binding guidance document that addresses geothermal-specific requirements the binding regulations do not cover. The key distinction: the Water Resources Act defines a "well" as an opening made to obtain water, which means closed-loop GSHP boreholes (sealed, no water withdrawal) technically fall outside the binding regulation. NL's own guidance document acknowledges this gap explicitly. In practice, the Guidelines function as the operative standard.
Key requirements from the 2022 Guidelines:
- A licensed NL water-well driller is required for all GSHP boreholes (binding via Guidelines s. 5.5, even for residential closed-loop systems where the non-domestic permit is not required)
- A non-domestic well permit is required for commercial, institutional, and industrial GSHP systems; single-family residential closed-loop systems and shallow systems (less than 5 m deep, covering most horizontal loops) are exempt from the permit
- Commercial and institutional systems must be designed by a registered Professional Engineer (PEGNL) with required Hydrogeologist input per CSA CAN/CSA-C448
- Closed-loop boreholes must be fully grouted from bottom to top with low-permeability material (pure bentonite recommended); no gaps permitted in borehole annulus
- 30-metre setback from the nearest water well is required for all GSHP boreholes
- Methanol is prohibited as a heat-transfer fluid; approved additives per CSA list only
- Maximum typical drilling depth is around 450 m; projects on the west coast of NL with boreholes extending into deep strata should consult the Department of Industry, Energy and Technology's Petroleum Development Section given gas-prone geology in some areas
- Open-loop systems may not discharge or inject water back into any well or borehole; injection wells to the aquifer are prohibited regardless of depth
- An electrical permit (under the Electrical Regulations NLR 96/120) is required for every GSHP installation from the Department of Digital Government and Service NL
Fee amounts for the non-domestic well permit and the well driller licence are set by regulation but were not publicly confirmed at the time of our research; contact the Water Resources Management Division or visit the permits tool for current fee information.
Newfoundland & Labrador climate and ground conditions
Newfoundland and Labrador spans a wide climate range — from the maritime-influenced Avalon Peninsula (St. John's averages roughly 4,800 heating-degree days) to the subarctic interior of Labrador (Goose Bay exceeds 7,000). That heating load is exactly where geothermal performs best: ground temperatures at loop depth remain stable year-round regardless of surface conditions, delivering consistent COP even when air temperatures drop well below -20°C.
Bedrock quality varies significantly by region. The Avalon Peninsula has relatively shallow bedrock overlaid by thin glacial till, which can make vertical drilling straightforward in many locations. The west coast has different geology and some areas with gas-prone deep strata — site assessment is important there. Horizontal loop installations are feasible on larger rural properties but most urban and suburban installations in NL use vertical closed-loop systems given lot size constraints.
With oil heat dominant and fuel prices subject to global market swings, NL homeowners using oil typically see payback periods that compare well against other provinces, even without a provincial rebate. Speak with a listed contractor about a site-specific cost analysis before committing to a system size and loop design.
