Nova Scotia's coastal climate is milder than most of inland Canada but still delivers meaningful heating loads — Halifax sees around 4,000–4,400 heating degree-days annually, and the province's older housing stock runs heavily on oil heat. That combination makes Nova Scotia a strong geothermal market: the ground holds 6–9°C at depth across most of the province, oil-to-geothermal switching is a financially sound move even without rebates, and the province has 27 verified contractors in our directory — the largest count of any Atlantic province. The main provincial rebate program (Efficiency NS Green Heat) closed at the end of 2025, but the federal Oil to Heat Pump Affordability Program remains an option for oil-heated homes.

Top Nova Scotia cities for geothermal contractors
Halifax and the Halifax Regional Municipality account for the largest concentration of Nova Scotia geothermal contractors. Cape Breton, the Annapolis Valley, and the South Shore have active installers serving both residential and light commercial projects. Coastal properties with large lots sometimes suit horizontal loop systems where geology and soil depth allow.

Nova Scotia geothermal incentives in 2026
Nova Scotia's main geothermal rebate program closed at the end of 2025. The federal oil-to-heat-pump program is geothermal-eligible but its Nova Scotia allocation was fully committed in early 2026. Check the links below for current status before planning your project budget.
- Oil to Heat Pump Affordability Program (OHPA) — Federal grant, geothermal-eligible (ground-source heat pumps meeting CSA C448 are explicitly covered). Up to $15,000 total when co-delivered ($10,000 federal + $5,000 Nova Scotia provincial top-up). Eligibility: oil heating, income at or below median, grid-connected. Important: as of early 2026, Nova Scotia's OHPA allocation is fully committed and new applicants are on a standby list only. The program may reopen if additional federal or provincial funding is secured — check efficiencyns.ca for current status. Details at our Canada rebates guide.
Nova Scotia geothermal regulations & well-drilling rules
Well construction in Nova Scotia is governed by the Well Construction Regulations, N.S. Reg. 382/2007, under the Environment Act, S.N.S. 1994-95, c. 1, administered by Nova Scotia Environment and Climate Change (NSECC). All certification is administered through NSECC; written and field exams are run through the Nova Scotia Groundwater Association.
Who must be certified: Anyone drilling, repairing, modifying, or decommissioning a drilled well on land they do not own or lease must hold a current Well Driller's Certificate of Qualification. Annual fee: $350 for one drilling machine, plus $145.75 for each additional machine. Certificates expire December 31 each year; renewal requires 100 Continuing Education Points over a four-year cycle. Landowners drilling on their own land are exempt. Unlicensed assistants may work under direct supervision of a certificate holder.
Closed-loop boreholes — regulatory gap: The Well Construction Regulations define "well" as an opening made "for the purpose of obtaining groundwater supply." A sealed closed-loop borehole does not extract groundwater, so it falls outside that statutory definition. The regulations contain no geothermal or heat pump provisions at all. In practice, Nova Scotia installers use certified Well Drillers for borehole work (the same equipment and operators are involved), but there is no explicit regulatory requirement that closed-loop boreholes be drilled by a certified Well Driller. This is a recognized regulatory gap. Consult NSECC at [email protected] before assuming either that certification is or is not required for your specific project.
Open-loop systems: Open-loop GSHP systems that extract groundwater are within NSECC's scope. Systems withdrawing more than 23,000 L/day may require a water withdrawal approval under the Activities Designation Regulations.
New legislation (April 2026): The Subsurface Energy Resource Extraction Act passed as part of the omnibus Powering the Economy Act in April 2026. This Act replaces the Petroleum Resources Act and regulates commercial geothermal, natural hydrogen, helium, and carbon storage. It appears targeted at commercial and deeper subsurface energy projects (mid-depth aquifers and power-generation reservoirs), not shallow residential GSHP. However, implementing regulations have not yet been confirmed as published, and the Act's exact scope for residential ground-source heat pumps has not been formally clarified. Until NSECC or the Province publishes specific guidance, the Well Construction Regulations remain the operative framework for residential GSHP borehole drilling.
Well construction records are required at completion of every drilled well, with copies to the owner and to NSECC (submitted by January 31 following the installation year). Use our permits tool for Nova Scotia-specific permit guidance.
Nova Scotia climate and ground conditions
Nova Scotia's maritime climate softens the winter extremes found further inland, but heating loads are still substantial. Halifax's design temperature runs around -18°C; northern mainland areas and Cape Breton can be colder. The province's housing stock is among the oldest in Canada, with a high proportion of oil-heated homes — many over 50 years old and with limited insulation. That aging stock is both the biggest driver of geothermal interest and a factor that affects system sizing: an energy audit and air-sealing work often accompanies a geothermal retrofit.
Ground temperatures in Nova Scotia range from about 6°C near the coast to 8–9°C in inland valleys at typical borehole depths (75–120 m). The province's bedrock geology is diverse — the South Shore and Cape Breton feature crystalline rocks (granite, quartzite) with good thermal conductivity, while the Annapolis Valley has softer sedimentary formations. Bedrock depth varies widely, which affects both borehole design and drilling cost. Local contractors familiar with provincial geology will size your loop field accordingly.
The practical case for geothermal in Nova Scotia is primarily the oil-to-geothermal switch: replacing an oil furnace with a ground-source system eliminates fuel price volatility, cuts operating costs significantly over the system life, and reduces carbon emissions. Even without the Green Heat rebate program that closed in late 2025, the economics of switching from oil are often favourable over a 15–20 year horizon.
