Update: CDAP Is Now Closed
CDAP stopped accepting new applications on February 19, 2024. The stacking strategies below that reference CDAP are preserved for historical context. BDC's Data to AI program is the successor and can be combined with IRAP and SR&ED. Visit bdc.ca for details.
Most Canadian businesses apply to one government funding program and stop there. But IRAP, SR&ED, OIDMTC, and BDC Data to AI are designed to be complementary. Each covers different activities, different cost categories, and different stages of your AI journey — which means you can legally combine them to recover a much larger share of your investment.
This guide explains which programs can be stacked, the rules you need to follow, and how to structure your projects so that one dollar of spending can be claimed across multiple programs without violating any "double-dipping" restrictions.
Why Grant Stacking Works in Canada
The Canadian government deliberately structures funding programs to cover different parts of the innovation lifecycle. CDAP funds strategic planning, IRAP funds technical R&D labour, SR&ED provides tax credits on experimental development, and OIDMTC covers digital media production. As long as you do not claim the same expense under two programs, you can participate in all of them simultaneously.
The key principle: different expenses, different programs. A single AI initiative often involves planning costs (CDAP-eligible), developer salaries for experimental work (SR&ED-eligible), contractor fees for technical prototyping (IRAP-eligible), and interactive digital content creation (OIDMTC-eligible). One project, four funding sources.
Grant Stacking Compatibility
| Combination | Compatible? | Key Rule |
|---|---|---|
| CDAP + IRAP | Yes | CDAP covers the digital adoption plan; IRAP covers R&D implementation |
| CDAP + SR&ED | Yes | CDAP covers advisory fees; SR&ED covers experimental development wages |
| IRAP + SR&ED | Partial | Must reduce SR&ED claim by IRAP amount received for same expenses |
| SR&ED + OIDMTC | Yes | Different qualifying activities — experimental R&D vs. digital media production |
| CDAP + OIDMTC | Yes | Planning costs vs. production costs — no overlap |
| IRAP + OIDMTC | Yes | Technical R&D vs. digital media — distinct activities |
Strategy 1: CDAP + IRAP
This is the most common stacking combination. Start with CDAP to fund your digital adoption plan (up to $15,000 in advisory grants), then use the plan to justify an IRAP application for the technical implementation. IRAP funds R&D labour — developers, data scientists, QA engineers — that CDAP does not cover.
- •CDAP covers: Digital advisor fees, strategic planning, technology roadmap
- •IRAP covers: Developer salaries, prototyping costs, technical project management
- •Combined potential: $15,000 (CDAP grant) + $50,000–$500,000 (IRAP contribution) + $100,000 (BDC loan at 0%)
Strategy 2: IRAP + SR&ED
This combination requires careful accounting. When you receive IRAP funding for R&D salaries, you must reduce your SR&ED qualified expenditure pool by the IRAP amount for those same expenses. However, many AI projects have expenses that qualify for SR&ED but not IRAP (materials, overhead, subcontractors), and vice versa.
The practical approach: allocate team members' time carefully. Developers doing experimental AI work (novel model architectures, unproven approaches) go under SR&ED. Developers doing technical implementation of proven approaches go under IRAP. Keep clean timesheets for each.
Full Stack Example: $500K AI Project
Consider a Canadian SMB investing $500,000 in an AI-powered quality control system for their manufacturing line:
| Expense Category | Amount | Program |
|---|---|---|
| Digital advisor & strategy | $15,000 | CDAP (100% covered) |
| R&D developer salaries (experimental) | $200,000 | SR&ED (35% refundable = $70,000) |
| Technical implementation labour | $180,000 | IRAP (up to 80% = $144,000) |
| Equipment & cloud compute | $60,000 | BDC loan (0% interest via CDAP) |
| Project management & overhead | $45,000 | SR&ED overhead proxy (55%) |
Total potential recovery: ~$229,000 in grants and credits plus $100,000 in interest-free financing — from a $500,000 investment. That is a 46% effective cost reduction through legal grant stacking.
Common Stacking Mistakes to Avoid
- •Double-claiming the same salary: If developer hours are funded by IRAP, those same hours cannot be claimed under SR&ED. Track time by project activity, not just by employee.
- •Misallocating CDAP and IRAP: CDAP covers planning and advisory — not implementation labour. Do not try to claim developer time under CDAP.
- •Forgetting to reduce SR&ED by government assistance: Any IRAP or NRC funding received must be deducted from your SR&ED qualified expenditure pool. Failing to do this can trigger a CRA audit.
- •Not keeping separate records: Each program has different documentation requirements. Maintain distinct project codes, timesheets, and expense categories for each funding source.
Optimal Stacking Timeline
The order in which you apply matters:
- 1.CDAP first — get your digital adoption plan funded and your BDC loan approved. The plan itself becomes supporting documentation for other applications.
- 2.IRAP second — apply for technical R&D funding using the CDAP plan as your project roadmap.
- 3.SR&ED ongoing — file SR&ED claims annually as you perform experimental development. Track eligible work from day one.
- 4.OIDMTC if applicable — claim Ontario's digital media tax credit for any qualifying interactive digital content produced during the project.
