Geothermal heat pumps are regulated provincially in Canada, not federally. Each province licenses the people who drill ground loops and sets its own rules for wells, permits, and environmental review. The single biggest factor is your loop type: a sealed closed-loop borehole touches no groundwater, while an open-loop system pumps and returns groundwater and triggers extra water-use authorizations almost everywhere. The national installation standard referenced by most programs is CSA C448, and many designers hold the IGSHPA Certified GeoExchange Designer (CGD) credential. Regulations verified May 2026 — rules change; confirm current requirements with the provincial authority and your licensed installer before drilling.
How geothermal is regulated in Canada
There is no national geothermal drilling permit. Authority sits with each province's environment or natural-resources ministry, which licenses drillers and, in most provinces, requires a record or report for each well. The practical fault line runs between two designs. Closed-loop systems circulate fluid through sealed pipe and, because they obtain no groundwater, sometimes fall outside a province's "well" definition — though in practice a licensed well driller is still used. Open-loop systems draw groundwater through the heat pump and return it, so they layer a water licence or water-rights authorization on top of the standard drilling and building permits, and they take longer to approve.
Two credentials come up repeatedly. On the trades side, several provinces have a dedicated certificate for ground-loop drilling (British Columbia's Geoexchange Driller, Alberta's Earth Loop Technician), while others fold it into a general water-well driller licence. On the design side, the IGSHPA Certified GeoExchange Designer (CGD) is the common professional qualification, and CSA C448 is the conformance standard most rebate programs require the installed system to meet. The province-by-province summaries below cover who may drill, which permits apply, and where to confirm the details.
Provincial geothermal regulations
Ontario
Regulator: Ministry of the Environment, Conservation and Parks (MECP).
Ontario regulates ground loops under two statutes: the Ontario Water Resources Act (via O. Reg. 903: Wells) and the Environmental Protection Act (via O. Reg. 98/12: Ground Source Heat Pumps). Drilling is done by a holder of an MECP Well Technician Licence working for a company with a Well Contractor Licence. A vertical closed-loop system deeper than 5 m needs an Environmental Compliance Approval under O. Reg. 98/12 — that approval carries a minimum 45-day public review period and a work plan prepared by a licensed engineer or professional geoscientist. Open-loop systems and any borehole meeting the "well" definition require a Well Record under O. Reg. 903, and a municipal building permit applies to the equipment, with the system expected to conform to CSA C448. Specific setback distances and current application fees are not stated here — confirm them with the MECP Wells Help Desk.

Quebec
Regulator: Ministère de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP), with contractor licensing through the Régie du bâtiment du Québec (RBQ).
Quebec is report-based rather than pre-approval-based: there is no provincial environmental approval for a standard residential closed-loop system. The governing framework is the Règlement sur le prélèvement des eaux et leur protection (RPEP, Q-2, r. 35.2), whose Chapter IV (Articles 28–30) covers geothermal. Before installation you obtain a municipal authorization; the drilling enterprise files a drilling report; and the installer files an Article 30 completion report within 30 days of finishing the work. Heat-pump mechanical work must be done by an RBQ-licensed contractor. Article 29 prohibits ethylene glycol, methanol, and potassium acetate as heat-transfer fluid in new closed-loop systems and restricts siting near shorelines and flood zones. Quebec does not require a separate provincial drilling licence comparable to Ontario's; confirm RBQ subcategories and any municipal fees locally.

British Columbia
Regulator: Ministry of Water, Land and Resource Stewardship, with trade certification through SkilledTradesBC.
British Columbia regulates well drilling under the Water Sustainability Act and the Groundwater Protection Regulation (B.C. Reg. 39/2016). A closed-loop geoexchange well must be drilled by a SkilledTradesBC-certified Geoexchange Driller — a standard Water Well Driller is explicitly not qualified to construct closed-loop geoexchange wells. Notably, no per-project drilling permit is issued for a closed-loop well: the requirement is that the driller be registered, and a well-construction report is filed after the work. Open-loop systems that use groundwater for non-domestic purposes need a water licence under the Water Sustainability Act, with a one-time application fee and annual rentals. A municipal building permit applies to the mechanical system. Confirm certification details with SkilledTradesBC and open-loop licensing with FrontCounter BC.

Alberta
Regulator: Alberta Environment and Protected Areas, under the Water Act (with the Alberta Energy Regulator for deep boreholes).
Residential ground-source heat-pump boreholes are regulated under Alberta's Water Act, not the Geothermal Resource Development Act — the GRDA applies only to deep geothermal resources and does not cover residential or commercial heat pumps. Since January 1, 2020, the drilling contractor must hold a Class F "Approval to Drill" from Alberta Environment and Protected Areas, and the rig must be operated by a certified journeyman Earth Loop Technician (trade 0351) or by a business employing one. Applications go through the department's Digital Regulatory Assurance System (DRAS). Drilling deeper than roughly 150 m (below the Base of Groundwater Protection in most areas) is regulated separately by the Alberta Energy Regulator. A municipal building permit covers the mechanical and electrical installation. Class F approval fees are not published here — confirm them with Alberta Environment and Protected Areas.

Manitoba
Regulator: Groundwater Management Section, Manitoba Environment and Climate Change.
Manitoba licenses well drilling under The Groundwater and Water Well Act, with the General Matters Regulation (M.R. 214/2015) and Well Standards Regulation (M.R. 215/2015). Closed-loop geothermal wells fall under a dedicated Class 2 well-drilling contractor licence (Class 1 also covers them), and every applicant must carry at least $2 million in liability insurance. Driller licence fees run $100 per year for Class 1 or 2. There is no per-project permit for standard closed-loop work, but a Sensitive Groundwater Area permit is required inside designated areas (such as the Rockwood Sensitive Area north of Winnipeg), and an open-loop system drawing more than 25,000 L/day of groundwater needs a Water Rights Act licence. A municipal building permit applies. Confirm thresholds with the Groundwater Management Section.

Saskatchewan
Regulator: Water Security Agency (WSA).
Saskatchewan regulates the drilling machine rather than the individual driller. Under the Ground Water Regulations (Sask. Reg. 172/66), no one may operate a drilling machine "for the purpose of obtaining ground water or scientific data on ground water" unless the machine is registered with the WSA, and a notice of drilling must be mailed before work begins. On the wording of those regulations, a sealed closed-loop borehole obtains no groundwater and contains no geothermal-specific provisions, so closed-loop drilling appears to fall outside the machine-registration requirement — but the WSA has not published an official position, so confirm directly with the WSA before drilling. Open-loop systems clearly fall under the Act: they require machine registration, a notice of drilling, and a Water Rights Licence for non-domestic use. A municipal building permit applies under Saskatchewan's National Building Code adoption (effective January 1, 2024).

Nova Scotia
Regulator: Nova Scotia Environment and Climate Change (NSECC).
All well work in Nova Scotia must be performed by a certified well driller holding a current Certificate of Qualification issued by NSECC under the Well Construction Regulations (N.S. Reg. 382/2007), made under the Environment Act. The certificate covers the work, so there is no separate per-project permit — though an inspector may require 24-hour pre-work notice. The well-driller certificate costs $350 per year for one drilling machine. Because the regulatory "well" definition turns on obtaining a groundwater supply, sealed closed-loop boreholes are not clearly captured; in practice operators still use certified well drillers. An open-loop system withdrawing more than 23,000 L/day may need a water-withdrawal approval under the Activities Designation Regulations. Note that the 2026 Subsurface Energy Resource Extraction Act regulates commercial and deeper subsurface energy; its application to shallow residential heat pumps is not yet clarified pending regulations.

New Brunswick
Regulator: Department of Environment and Local Government (NBDELG).
New Brunswick regulates well construction under the Water Well Regulation (N.B. Reg. 90-79), made under the Clean Water Act. Two annual permits are required: a Well Contractor Permit ($300 per year) for the company and a Well Driller Permit ($100 per year) for the operator, who must hold a water-well driller certificate of qualification. The annual permits cover all work performed in the permit year, so there is no separate per-project permit. A mandatory water-quality test follows construction within 12 months. As in the other Atlantic provinces, the "well" definition turns on obtaining water, so sealed closed-loop boreholes are not clearly captured — and in practice drillers obtain standard well permits. An open-loop system that withdraws and reinjects groundwater at volume may need additional Clean Water Act approval. Confirm current fees with NBDELG.

Newfoundland and Labrador
Regulator: Department of Environment and Climate Change, Water Resources Management Division (WRMD).
Under the Water Resources Act (SNL 2002, c. W-4.01) and the Well Drilling Regulations (NLR 63/03), no one may drill a well for gain without a licence, and the province's 2022 Guidelines for the Construction of Ground Sourced Heat Pump Systems state that GSHP boreholes must be constructed by a licensed water-well driller. Single-family closed-loop systems and shallow systems under 5 m are exempt from the non-domestic well permit; non-domestic or commercial systems need that permit. A surface-water, pond, or vertically submerged loop needs a permit to alter a body of water under the Act, and the heat-pump electrical work needs an electrical permit. There is no stand-alone geothermal drilling permit — for non-residential systems the non-domestic well permit serves that role. Confirm current fees with the Water Resources Management Division.

Prince Edward Island
Regulator: Department of Environment, Energy and Climate Action (Land and Environment).
Prince Edward Island has the most explicit geothermal treatment of the Atlantic provinces. Under the Well Construction Regulations (W01-1-4), made under the Water Act, vertical and inclined geothermal boreholes are regulated as wells and must be drilled by a licensed well driller; horizontal-loop systems are expressly excluded from the "well" definition and need none of the well requirements. A Well Driller's Licence costs $200 initially ($100 renewal) and a Well Contractor's Licence $500 ($250 renewal), each on a 24-month term. A $25 Well Permit is triggered only when a closed-loop system uses more than 5 wells, exceeds 250 m of combined bore length, or sits in a Schedule A restricted area. High-capacity or central-supply wells need additional groundwater-exploration and water-withdrawal permits. These fee amounts are confirmed from official PEI sources.

What this means for your project
Across every province the practical advice is the same: hire a licensed driller and a contractor who pulls the required permits as a line item in their proposal. Closed-loop systems are the simpler path almost everywhere — they avoid the water-licensing layer that open-loop systems trigger. Because fees, forms, and licence tiers change from year to year, treat the summaries above as a starting point and verify the specifics with your provincial regulator before you sign a contract. Our permit lookup tool returns the driller, well, building, and environmental-review requirements for your province in two questions, and the Canadian rebates guide shows which federal and provincial incentives you can stack on the install.
This guide summarizes provincial geothermal regulations as of May 2026 and is general information, not legal advice. Requirements change and vary by municipality; always confirm current rules with the relevant provincial authority and your licensed installer before drilling.
