Ontario Critical Minerals Innovation Fund (CMIF)
Eligibility & Details
What this program funds and who can apply
Program Description
A competitive, project-based grant program from the Ontario Ministry of Energy and Mines that funds up to 50% of eligible costs (maximum $500,000) for private-sector R&D and commercialization projects advancing critical minerals technologies. The fund targets the battery supply chain and advanced mining sectors and is administered through the Transfer Payment Ontario (TPON) portal. Disbursements follow a three-instalment schedule tied to agreement execution and interim/final reporting milestones. The 2025-26 intake closed; a 2026 Q2/Q3 reopening is anticipated based on program cadence.
Eligibility Requirements
- Private-sector businesses incorporated in Ontario
- Projects must occur in Ontario and involve critical minerals technologies
- Eligible activities include R&D, prototyping, testing, IP protection, feasibility testing, and commercialization of critical minerals innovations
- Collaborations with academic or research institutions are permitted and encouraged
- Cannot receive concurrent funding from other Ontario government programs for the same project
- Applicants must not be listed under applicable sanctions legislation or affiliated with named research organizations of concern
- Only one project per applicant per intake round

How to Win
Insider tips, common pitfalls, and what successful applicants look like
Insider TipFederal-provincial stacking is allowed but total government assistance cannot exceed 75% of eligible costs — this means a company using the federal CMRDD (id 69) alongside CMIF needs to ensure combined government support stays under that ceiling. Projects in battery minerals processing or recycling with a clear Ontario supply-chain story score best; pure mining exploration projects (no R&D component) are out of scope. Check the TPON portal rather than the Ontario.ca page for live intake status — the main page lags by a few days.
Success Profile
An Ontario-based mining company, processing firm, or battery materials manufacturer that has an existing technology ready for advanced prototyping, pilot-scale testing, or scale-up to a mine-site demonstration. The strongest candidates have a clear link to the battery supply chain or strategic mining innovation, a credible technical team, and matching funding already committed or secured from private partners.
Evaluation Criteria
Applications are scored on technical merit of the proposed innovation, economic benefit to Ontario's critical minerals and battery supply chain sector, project feasibility and milestone clarity, applicant's capacity to execute, and appropriateness of the budget. Federal-provincial alignment with the Critical Minerals Strategy is an advantage. The program is discretionary and non-entitlement — scoring well on all criteria does not guarantee funding.

Compatible programs, clawback risk, and combined funding potential

Clawback Risk
Medium RiskFunding is repayable if the project departs materially from agreed terms, eligible expenses cannot be substantiated, or the organization misrepresents eligibility information. The milestone-based instalment structure limits clawback exposure to the disbursed amounts at each stage.
