OIDMTC 2026: The Complete Guide to Ontario's Digital Media Tax Credit

If you build interactive software, games, or educational products in Ontario and you aren't claiming the Ontario Interactive Digital Media Tax Credit, you are likely leaving more money on the table than your SR&ED file is bringing in. OIDMTC is a fully refundable provincial credit that returns up to 40% of qualifying Ontario labour and certain marketing costs on eligible interactive digital media products. Unlike SR&ED, it isn't gated by scientific uncertainty — it's gated by product type, purpose, and where the work happens. This is the practitioner guide we wish every Ontario studio had read before their first claim.

What OIDMTC is — in one paragraph

OIDMTC is a refundable Ontario corporate tax credit, jointly administered by Ontario Creates (the certifying agency) and the Canada Revenue Agency (which administers the credit on behalf of the province through the T2 return). The product side — eligibility of the product, eligibility of the corporation, eligibility of expenditures — is reviewed by Ontario Creates, which issues a Certificate of Eligibility. The financial side — computing the credit and paying it out — is handled through your corporate tax return when that certificate is filed alongside the Schedule T2-Schedule 560. The credit is refundable, which means it isn't applied to reduce tax payable first and then carried forward — it's paid directly to the corporation. For a studio operating below breakeven, OIDMTC effectively functions as a quarterly-to-annual cash injection on top of SR&ED.

The three rate tiers

Most founders we talk to assume OIDMTC is "the 40% credit." It isn't. There are three distinct rate tiers, and the one that applies to your corporation depends on what you built, who paid for it, and how big your gaming labour base is. Get this wrong and you'll either under-claim or, worse, claim under the wrong category and trigger an Ontario Creates question that delays certification by six to nine months.

The first two tiers (40% non-specified and 35% specified) are claimed on a product-by-product basis — every game, every interactive product, gets its own Certificate of Eligibility from Ontario Creates. The third tier — qualifying digital game corporations — is a separate stream designed for studios whose entire business is game development. Instead of certifying every game individually, qualifying corporations file annually for all eligible game work that meets the program's tests. This is a meaningful operational difference: studios above the threshold spend dramatically less time on certification paperwork over a multi-year claim history.

Choosing between non-specified and qualifying digital game corporation

Studios that ship their own games and meet the digital-game-corporation labour threshold sometimes assume they should default to the qualifying digital game corporation stream because of the lighter paperwork. The rate difference matters: that's 40% versus 35% — a five-percentage-point haircut. On a $3M Ontario labour base, that's $150,000 a year. The right answer depends on volume. A studio shipping one big self-funded title per fiscal year is usually better off in the 40% non-specified stream, accepting the per-product certification work. A studio with many concurrent titles, a higher labour base, and limited internal admin capacity may net out ahead in the 35% qualifying digital game corporation stream because the certification overhead drops sharply.

What counts as an "interactive digital media product"

The eligible-product definition is the part of OIDMTC that trips up the most claims. To be eligible, a product must satisfy three tests simultaneously:

"Interactive" is doing a lot of work in that definition. A product that merely plays media — a video, a slideshow, a streaming audio file — is not interactive. The user must be able to influence the content meaningfully through input. A linear documentary that lets the viewer pause and rewind is not interactive. A branching narrative that changes outcomes based on user choices is. Educational simulations where a learner manipulates variables and sees results: interactive. A static online textbook with embedded video: not.

"Primarily" is doing similar work on the Ontario-development side. Ontario Creates expects the substantive creative and technical development — design, programming, art, scripting — to happen in Ontario by Ontario residents. Outsourcing a portion of art to a studio in Quebec, or contracting QA in India, doesn't automatically disqualify a product, but the program will look at the share of total development effort that happens in Ontario versus elsewhere. The closer that ratio sits to 50%, the more carefully your application needs to walk the reviewer through the breakdown.

Eligible Ontario labour costs

The core eligible expenditure category for all three tiers is Ontario labour. This includes:

• Salaries and wages paid to Ontario-based employees for work directly attributable to the eligible product
• Remuneration paid to arm's-length individuals — freelancers and individual contractors — for eligible work performed in Ontario
• Remuneration paid to arm's-length corporations for services rendered in Ontario, subject to specific look-through and allocation rules

Three rules apply ruthlessly here. First, the labour must be for work that directly contributed to the eligible product — not general corporate overhead, not unrelated R&D, not marketing labour outside the marketing cap. Second, the person performing the work must be ordinarily resident in Ontario at the relevant time — payroll address alone isn't sufficient if the individual was working remotely from another province for a portion of the year. Third, related-party labour (for example, payments to a non-arm's-length corporation) is sharply limited; OIDMTC has explicit anti-avoidance rules to prevent claiming the same labour twice through a chain of related entities.

The labour calculation is granular. We typically build a per-employee, per-product, per-month allocation grid that ties payroll records to product milestones. If a developer spent 60% of January on Product A, 30% on Product B, and 10% on internal tooling, that's three separate allocations, with the 10% tooling time being excluded from both products. Ontario Creates will ask for the underlying allocation methodology during certification.

The marketing and distribution allowance

OIDMTC is unusual among Canadian provincial credits in that, for non-specified products only, it also covers a slice of marketing and distribution costs. The rules:

• Capped at $100,000 per eligible product
• Available only for non-specified products (the 40% stream); not available for specified products or qualifying digital game corporations
• Must be incurred within the eligible expenditure window for the product
• Includes advertising, promotional activities, and distribution costs directly tied to the eligible product

$100,000 of marketing costs at the 40% rate is a $40,000 cash refund. For a self-funded studio shipping a $1-2M-budget title, that's a meaningful contribution to launch spend — and it's one of the only places in the Canadian incentive system where marketing money is refundable. The catch is that the marketing must tie cleanly to the eligible product. Generic brand marketing for the studio itself doesn't qualify. Influencer campaigns, ad buys, conference appearances, and PR activities targeted at promoting the specific product are the bread and butter of this allowance.

What's excluded

Some product categories are simply outside OIDMTC's scope, no matter how interactive they are. The exclusion list is the second-most-common reason applications fail certification (after the purpose test). The program explicitly excludes:

A few of these exclusions deserve explicit attention because they catch otherwise-strong applications:

Productivity software. If your product helps users do work — track tasks, manage projects, build something, organize information — it's a productivity tool, not an interactive digital media product. The "fun" overlay matters less than the dominant use case. A gamified task manager is still a task manager.

Financial services. Trading platforms, robo-advisors, banking apps, accounting tools, and similar products are categorically excluded. This is a hard line; we've seen fintech founders argue that their interactive onboarding flow should qualify. It doesn't.

News and blogs. Even highly interactive editorial products — data-driven journalism, interactive long-form, multimedia explainers — tend to fail because the dominant purpose is news delivery rather than education or entertainment in the OIDMTC sense.

Communication products. Messaging, video calling, social platforms, and forums are excluded because their primary purpose is interpersonal communication, not media delivery. Even with rich interactivity layered on top, the core categorization usually wins.

Pre-certification through Ontario Creates

Unlike SR&ED, where eligibility is essentially decided at audit (after the claim is filed), OIDMTC eligibility is decided up front by Ontario Creates. This is one of the most important structural differences between the two programs, and it changes how a studio should approach risk.

For SR&ED, you file the T661 with your T2, the CRA processes the claim, and if reviewed, you may end up defending the technical narrative twelve to eighteen months later. The uncertainty rides through to the audit. For OIDMTC, Ontario Creates reviews the product itself, the corporation, and the expenditures, and issues a Certificate of Eligibility. The certificate is then filed with the T2. Once issued, the certificate represents a firm provincial determination — the CRA's role is largely arithmetic.

This has two implications. First, it removes most of the eligibility uncertainty from the back-end audit. If Ontario Creates certified the product, the credit gets paid. Second, it pushes all of the documentation work to the front of the process, where it's easier to get right. A well-prepared OIDMTC application sets the studio up for clean refunds for years to come. A sloppy one creates a months-long question-and-answer cycle with Ontario Creates that delays cash.

What Ontario Creates looks at during pre-certification:

• Corporate eligibility: Canadian-controlled, taxable Canadian corporation, with a permanent establishment in Ontario for the relevant tax year. Not exempt from tax, not controlled by such a corporation, and not a prescribed labour-sponsored venture capital corporation.
• Product eligibility: Detailed description of the product, design documents, gameplay or interaction flow, content samples, and the case for purpose, interactivity, and Ontario development.
• Expenditure eligibility: Schedule of Ontario labour by individual, period, and product allocation. Marketing-and-distribution schedule (for non-specified products). Supporting payroll and invoice records.
• Anti-stacking confirmations: Disclosure of any other Ontario tax credits or government assistance related to the same expenditures, since OIDMTC interacts with other Ontario credits in specific ways.

Application process and timelines

How OIDMTC interacts with SR&ED

This is the question we get most often from Ontario game studios and edtech founders: "Can I claim both?" The short answer is yes — on the same project, the same fiscal year, even the same employees — but only for the portions of work that qualify for each program. The work has to be carved up correctly, because the two programs cover different things.

SR&ED covers scientific or technological work resolving uncertainty. A custom physics engine that pushes past what was readily available in the market when the work began; a novel netcode architecture solving latency problems; a machine-learning system for procedural content generation. The eligibility test is technical, framed by CRA Information Circular IC 2012-02 and the S/THERI framework (uncertainty, hypothesis, experimentation, results, iteration).

OIDMTC covers development of the interactive digital media product itself. Gameplay programming, level design, art, audio, scripting, QA, project management directly tied to the product. The eligibility test is about purpose, interactivity, and Ontario development — not technical novelty.

In practice, the same engineer's time in a given month may split across both programs:

• The two weeks she spent debugging a novel netcode algorithm to handle 10,000 concurrent players: SR&ED-eligible. Also OIDMTC-eligible Ontario labour, because the work directly contributed to the eligible product.
• The week she spent on routine level scripting: not SR&ED-eligible (no technological uncertainty). But OIDMTC-eligible.
• The week she spent on internal HR tooling: not OIDMTC-eligible (not tied to the product). Not SR&ED-eligible either.

Both programs can be claimed on the same dollar of labour — but with a critical wrinkle. Ontario provincial assistance, including OIDMTC, must be netted against the SR&ED qualifying expenditure pool at the federal level. In plain terms: the OIDMTC credit you receive reduces the SR&ED qualifying expenditure base. The net result is still strongly positive — you're not double-claiming, you're stacking — but the federal SR&ED ITC amount is mechanically lower than it would have been absent the OIDMTC claim. For a Canadian-controlled private corporation eligible for the enhanced 35% SR&ED rate, the combined effective subsidy on jointly-eligible Ontario labour typically lands in the 55-65% range once OIDMTC, federal SR&ED, and the Ontario Innovation Tax Credit are all stacked correctly.

For studios building eligible interactive digital media products that also contain SR&ED-eligible technical work, the optimal structure is almost always to claim both. The administrative cost of running two parallel files is small compared to the cash on the table.

Common reasons OIDMTC applications fail

After years of working through OIDMTC files alongside SR&ED claims, the failure modes are predictable. The pre-certification process means problems show up early — usually in a deficiency letter from Ontario Creates — which is better than a surprise reassessment two years in but still painful and avoidable.

• Purpose test confusion. The product was built to drive sales of something else, even if it's wrapped in entertainment. Branded games, marketing experiences disguised as edutainment, and "sponsored learning" products fail repeatedly here.
• Failed interactivity test. Linear video products, even with chapter selection or branching commentary, don't meet the bar. Ontario Creates expects genuine user influence over content outcomes.
• Insufficient Ontario development. A studio with a registered office in Ontario but a development team distributed across BC, Quebec, and outside Canada will struggle to prove the work happened "primarily in Ontario." Track Ontario residency carefully; the program audits this.
• Product/corporation mismatch. The IP is held by a parent or sister entity, while the labour is incurred by the Ontario operating entity. OIDMTC requires the claimant corporation to develop the product. Inter-company structures need to be designed with this in mind before work starts.
• Specified versus non-specified confusion. Work that turns out to be fee-for-service to a publisher, but was claimed as non-specified (40%), gets reclassified to 35% on review — sometimes with consequences for marketing-cost claims that were valid only under the non-specified stream.
• Marketing costs without product linkage. Generic studio branding, recruiting ads, or corporate sponsorships claimed against the $100,000 marketing cap will be stripped. Marketing must promote the specific eligible product.
• Sloppy labour allocation. Aggregate payroll claimed without per-product or per-period allocation methodology. Ontario Creates expects defensible allocation documentation; "we estimated 80%" is not it.
• Missing or thin design documentation. For game products, the program expects design documents, gameplay videos or builds, art bibles, and other artifacts that establish what was actually built. Indie studios that operate without formal design documentation should generate the equivalent artifacts during the project, not retroactively.

Where OIDMTC fits in your broader funding stack

For an Ontario studio building eligible interactive digital media products with genuine technical R&D, the full provincial-plus-federal stack typically looks like:

• OIDMTC — 40% (or 35%) refundable on Ontario labour, with the marketing cap for self-funded products
• Federal SR&ED Investment Tax Credit — refundable at 35% for CCPCs up to the expenditure limit, on the qualifying R&D portion of the work
• Ontario Innovation Tax Credit (OITC) — 8% refundable on Ontario SR&ED expenditures, subject to limits
• Ontario Research & Development Tax Credit (ORDTC) — 3.5% non-refundable on Ontario SR&ED expenditures

Layered correctly — with proper attention to anti-stacking and Ontario's specific assistance-reduction rules — this stack puts a meaningful subsidy under every dollar of Ontario labour in your studio. The mechanics matter; the order of operations between OIDMTC, SR&ED, OITC, and ORDTC affects the final number, and reasonable people running the same labour base get different answers depending on how they handle the netting. This is where having someone do the integrated calculation, rather than treating each credit as a silo, pays for itself.

Is OIDMTC right for your business?

OIDMTC is a strong fit if you are an Ontario-based corporation building interactive digital media products that meet the purpose, interactivity, and Ontario development tests. The cleanest fits: independent game studios, edtech companies building learning products for K-12 or post-secondary, serious-games developers working on training and simulation, and producers of interactive narrative or cultural experiences. If most of your development team is in Ontario, most of your spend is Ontario labour, and your product clearly entertains, educates, or informs rather than promotes or transacts, you are almost certainly eligible for at least one of the three rate tiers.

It's a poorer fit — or outright ineligible — if you build productivity software, financial services applications, news products, blogs, communication tools, or any product primarily designed to promote another product or service. It's also a poor fit if your development is genuinely distributed across multiple provinces or countries and Ontario isn't the dominant location. And it's not a fit for non-corporate entities — sole proprietorships and partnerships are outside the program.

Final thoughts

OIDMTC rewards two things: the right product type, and disciplined documentation. The product part is binary — either your product fits the definition or it doesn't, and you'll know early in the design phase. The documentation part is process. Ontario Creates does the substantive eligibility work up front, which means studios that invest in clean records during the project enjoy years of smooth certifications and predictable refunds. Studios that don't end up in deficiency cycles that delay cash by quarters.

The single most important decision is structural: before material development spend, make sure (a) the corporation that will incur the labour is the corporation that will own the eligible product, (b) the work is genuinely happening in Ontario, and (c) you have a defensible per-product, per-employee, per-period time allocation in place. If those three things are true on day one of development, OIDMTC essentially becomes a back-office workflow rather than a project. If they're not, you'll spend more on consultants reverse-engineering the file than the program is worth.
