Clean-Energy CCA (Class 43.1/43.2) & Clean Tech ITC for Canadian Miners

Quick answer

On the clean-energy generation and heat-recovery equipment you install — potentially yes: Class 43.1 gives 30% declining-balance CCA (the old Class 43.2 50% rate applied only to property acquired before 2025), and the refundable Clean Technology ITC (s. 127.45) can add up to 30% of the capital cost for property acquired 2023-2033. But the ASIC rigs themselves are Class 50 (55%), not clean-tech, and whether a mine's clean-energy gear qualifies is genuinely fact-dependent — the Excise Tax Act (s. 188.2) already deems mining "not a commercial activity" for GST, which muddies the picture. Every rate below is quoted from the Income Tax Act / Regulations; the mining-specific answer is not a bright-line rule.

The rules, each with its statute

Class 43.1 — accelerated CCA at 30%

Income Tax Regulations, Schedule II Class 43.1; rate at Reg. 1100(1)(a)(xxix.1)

A capital-cost-allowance class for specified clean-energy generation and conservation equipment — electricity from solar, wind and water, stationary electricity storage, active solar heating, heat pumps, and heat-recovery / cogeneration equipment. Property in the class is written off at 30% declining balance (before the first-year rules), far faster than an ordinary building or general equipment.

Class 43.2 — accelerated CCA at 50%

Income Tax Regulations, Schedule II Class 43.2; rate at Reg. 1100(1)(a)(xxix.2)

A higher-rate (50% declining balance) class for a defined subset of the same clean-energy property. Critical recency point: the Class 43.2 window applies only to property ACQUIRED BEFORE 2025 and was not extended — equipment you acquire now generally falls into Class 43.1 at 30%, not 43.2 at 50%. Do not rely on 50% for a current purchase without confirming the property still qualifies for 43.2 at the statute.

Clean Technology ITC — 30% refundable credit

Income Tax Act s. 127.45

A refundable investment tax credit for eligible "clean technology property" — a defined subset of Class 43.1/43.2 (solar, wind, water, storage, geothermal), situated in and used exclusively in Canada and not previously used — for property acquired on or after March 28, 2023 and before January 1, 2034 (15% for 2034, nil after 2034). Two catches for a mine: the 30% is a MAXIMUM that drops to 20% if the prevailing-wage and apprenticeship labour requirements are not met; and "clean technology property" generally EXCLUDES most heat-recovery and cogeneration equipment — so a heat-recovery loop may earn the CCA class without earning the ITC. It can stack with the accelerated CCA on the same qualifying asset.

Your ASIC miners are NOT clean-technology property

Income Tax Regulations, Schedule II Class 50 (55%) — see the income-tax page

This is the correction that catches miners out: the mining rigs themselves are general-purpose electronic data-processing equipment — Class 50 at 55% CCA — not clean-tech. Class 43.1/43.2 and the Clean Tech ITC reach only the clean-energy generation and heat-recovery gear you install (on-site solar/wind, storage, a heat-recovery or cogeneration loop), never the ASICs.

Mining-context eligibility is a genuine grey area

Excise Tax Act s. 188.2 (GST framing) + fact-dependent ITA qualification

Whether a specific mining operation's clean-energy or heat-recovery equipment actually qualifies — and how the Clean Tech ITC interacts with a business whose mining activity the Excise Tax Act (s. 188.2) deems "not a commercial activity" for GST — is fact-dependent and not settled by a bright-line rule. Treat any 30%/50%/ITC number as the ceiling the statute allows for qualifying property, not a guarantee for a mine. This is where a tax professional is not optional.

What this page deliberately does not tell you

It does not tell you that your mine’s solar array, battery or heat-recovery loop will qualify for Class 43.1/43.2 or the Clean Tech ITC — that turns on the exact equipment, how it is used, and unsettled questions about mining and "commercial activity" that the CRA and courts, not this page, resolve. It also does not cover the labour and other conditions that can attach to the clean-economy credits. Treat the numbers as the statutory ceiling for qualifying property, and confirm your own case.
