Understanding Scientific and Technological Uncertainty in SR&ED
In the context of Canada’s Scientific Research and Experimental Development (SR&ED) program, one of the most critical pillars is demonstrating scientific or technological uncertainty. This refers to the knowledge gaps or limitations that prevent a business from achieving a desired outcome using standard or known methods. These uncertainties must be documented clearly and thoroughly to validate the SR&ED claim.
Unlike routine engineering or development, uncertainty implies that even experienced professionals cannot readily predict the result due to a lack of established methodologies or technical obstacles.
Why Documentation of Uncertainty Matters
Accurate documentation is not just a supporting factor—it’s central to eligibility. The Canada Revenue Agency (CRA) evaluates whether the claimed project truly pursued new knowledge or involved a systematic investigation to overcome real uncertainties.
Failing to document uncertainty with clarity can lead to rejected claims, reduced funding, or time-consuming audits. To mitigate this, having a structured documentation process is essential.
For a broader overview of what qualifies under the SR&ED program, see our complete SR&ED eligibility guide.
Types of Scientific and Technological Uncertainty
1. Technological Uncertainty
Occurs when existing technologies cannot meet a desired performance requirement. Examples include:
- Integration challenges with new hardware
- Scalability issues in software systems
- Limitations in existing materials or algorithms
2. Scientific Uncertainty
Arises when scientific theory or data is incomplete, and the outcome of an experiment is not known.
- This could include exploratory pharmaceutical research
- Biotechnology experiments
- Advanced AI learning models
Both types require detailed evidence of the knowledge gap and how it was explored.
How to Identify and Categorize Uncertainties
Begin by asking:
- What technical problem were you trying to solve?
- Were standard practices insufficient?
- Was there a gap in industry knowledge?
Clearly outlining the nature of the unknowns sets the foundation for documenting your SR&ED project properly. For further clarity, our article on common SR&ED misconceptions debunks what does and doesn’t qualify.
Step-by-Step Guide to Documenting Uncertainty
1. State the Core Technological Objective
Start with the intended advancement. What did you aim to achieve? This anchors your documentation and gives the CRA a benchmark to understand the scope.
Example: “Develop a cloud-based platform capable of processing real-time satellite imagery with 95% accuracy under varying light conditions.”
2. Describe the Knowledge Gap
Use clear language to show what wasn’t known at the time of the project.
Example: “There was no known algorithm that could accurately identify water bodies in night-time infrared satellite images due to signal distortion.”
3. List Previous Attempts and Failures
Outline what has already been tried and why those attempts failed. This adds credibility and shows genuine uncertainty.
Example: “Existing AI-based classifiers failed under 60% light conditions due to high image noise.”
4. Explain the Investigation Process
Here, show your hypothesis testing, trial-and-error, and experimentation steps. The CRA is looking for systematic work, not just luck or routine iteration.
Example: “Three model architectures were tested (ResNet, U-Net, and ConvLSTM), each evaluated under five lighting conditions. Only ConvLSTM provided a partial solution.”

5. Record Daily Logs and Meeting Notes
Use lab books, emails, code commits, and technical meetings to record uncertainty-related efforts. These logs can be invaluable during CRA reviews or audits.
Tools and Templates to Help You Document
Leverage templates and project management tools to track uncertainty systematically. Some helpful resources include:
- JIRA / Confluence for technical task logging
- Notion or Trello for experiment boards
- LabArchives for scientific notes
- CRA’s official SR&ED Guide for compliance parameters
You can also estimate your potential funding using our SR&ED calculator.
What the CRA Looks for in Uncertainty Documentation
Consistency Across Documentation
Ensure the same story is reflected in your:
- Technical reports
- T2 SCH 32/49 forms
- Supporting schedules
Linking Activities to Uncertainty
Each experiment or iteration should be tied back to a specific technological uncertainty.
Absence of Predictability
Avoid writing in past-tense certainty. CRA reviewers assess whether the result could have been predicted—so emphasize the unknowns and risks taken.
Common Mistakes to Avoid
- Using vague terms like “challenging” instead of “uncertain”
- Listing routine bug fixes or upgrades as “uncertainty”
- Submitting documentation that lacks a clear hypothesis or method
To avoid such pitfalls, many companies choose to work with a specialized SR&ED consultant to streamline the documentation process.
Real-Life Example: AI Model for Agricultural Forecasting
Objective: Improve yield prediction by integrating weather data with soil conditions using machine learning.
Uncertainty: No existing model successfully integrated satellite-derived soil moisture with historical rainfall to forecast specific crop yields in Ontario.
Approach: Multiple regression and neural network models were tested over three growing seasons. Data was noisy and seasonal fluctuations unpredictable.
Result: New model achieved 87% accuracy, but required unique pre-processing of multispectral satellite bands—previously undocumented.
This case clearly showcases how scientific and technological uncertainty can be validated with a structured, evidence-backed approach.
Final Thoughts: Make Uncertainty Your Strength in SR&ED
When properly documented, uncertainty becomes a strategic advantage. It proves to the CRA that you went beyond the obvious and pushed the boundaries of known technology or science.
Many businesses lose out on valuable funding simply because they don’t document uncertainties correctly. For those aiming to maximize SR&ED tax credits, treating documentation as a core part of your innovation cycle is a non-negotiable.
