Eligibility & Details
What this program funds and who can apply
Program Description
Non-refundable provincial tax credit of 3.5% of eligible scientific research and experimental development (SR&ED) expenditures incurred in Ontario by qualifying corporations. The ORDTC stacks on top of the federal SR&ED Investment Tax Credit and the Ontario Innovation Tax Credit (OITC), providing an additional layer of R&D tax relief for Ontario businesses. Unlike the OITC (which is refundable at 8%), the ORDTC is non-refundable and reduces Ontario corporate income tax payable only — unused amounts carry back 3 years or forward 20 years.
Eligibility Requirements
- Must be a corporation (not exempt from Ontario corporate income tax)
- Must have a permanent establishment in Ontario
- Must conduct scientific research and experimental development (SR&ED) activities in Ontario
- Must qualify for the federal SR&ED Investment Tax Credit under section 127 of the federal Income Tax Act
- Must file the federal SR&ED expenditure claim on form T661 for the taxation year

How to claim
Insider tips, common pitfalls, and what successful applicants look like
Insider TipThe ORDTC is often overlooked because it's non-refundable and 'only' 3.5% — but it's essentially free money for profitable Ontario corporations already claiming federal SR&ED. The OITC (refundable at 8%) takes priority in planning, but the ORDTC adds incremental value on top. Critical nuance: the Ontario Innovation Tax Credit (OITC) counts as government assistance that REDUCES your ORDTC eligible expenditure base — so claim them together but plan the interaction carefully with a tax advisor. Corporations with Ontario tax losses can still generate ORDTC credits; they carry forward 20 years. The ORDTC is not available on expenditures previously used to claim the OITC on the same amount (avoid double-counting).
Success Profile
Profitable Ontario corporations conducting significant SR&ED work — particularly technology companies, manufacturers, biotech/pharmaceutical firms, and cleantech companies. Most valuable to large Ontario corporations with substantial Ontario corporate income tax payable. Less valuable to early-stage companies with tax losses (though 20-year carry-forward preserves value).
Evaluation Criteria
No adjudication — automatic entitlement if qualifying conditions met. CRA verifies: (1) corporation qualifies for federal SR&ED ITC; (2) Ontario permanent establishment exists; (3) expenditures attributable to Ontario; (4) T661 filed within 18-month deadline; (5) corporation not tax-exempt.
