What Is the CSA Space Technology Development Program (STDP)?

The Space Technology Development Program (STDP) is a federal program delivered by the Canadian Space Agency (CSA). Its main goal is to help Canada’s space industry by supporting technology development that improves mission readiness and builds industrial capability.

The main objectives of STDP are:

• The program helps reduce technical risks for future space missions.
• It encourages industrial innovation in space technologies.
• It raises the readiness level of Canadian-developed space systems.

STDP uses targeted Announcements of Opportunity (AOs). Each AO focuses on a certain type of applicant or technology area.

CSA STDP Funding Streams for Small Businesses

The most relevant STDP funding stream for SMEs is the STDP AO for Small Businesses in Space R&D. The official name and number may change with each call, so always check the CSA website for the latest AO title and guidelines.

Who Is Eligible?

To be eligible under the small business AO, your business must:

• Be a Canadian small business (generally fewer than 50 employees)
• Be legally incorporated in Canada
• Carry out space technology R&D activities in Canada
• Show technical ability to deliver the project

Projects must support the development of space technologies, not general software or non-space applications.

What Types of Projects Qualify?

Eligible projects usually involve:

• Space system components or subsystems
• Payloads, instruments, or sensors
• Robotics, autonomy, or advanced materials for space use
• Technologies that increase Technology Readiness Levels (TRLs)

Projects focused only on commercialization, marketing, or non-technical activities do not qualify.

Other STDP Streams You Should Know About

While the small business AO is aimed at SMEs, the CSA also offers other STDP calls as your company grows.

STDP AO for Advanced or Emerging Space Technologies

This stream supports advanced or emerging space technologies and is open to a wider range of applicants, not just small businesses.

Core STDP Program

The main Space Technology Development Program supports a broad range of space technology development and industrial growth activities across Canada.

Tools like GrantHub’s eligibility matcher can help you compare STDP AOs and see which ones fit your company’s size, technology area, and province.

Eligible Expenses Under CSA STDP Funding

STDP funding covers only expenses directly tied to the approved R&D project. According to the CSA, eligible expenses include:

• Salaries and benefits for technical staff working on the project
• Direct R&D labour
• Specialized equipment and materials needed for space technology development
• Prototype development and testing costs
• Subcontracting for technical expertise specific to the project

General overhead, sales and marketing, and unrelated business costs are not eligible under CSA STDP funding. Always check the AO guidelines for a full list of eligible and ineligible expenses.

Common Mistakes to Avoid

1. Applying with a non-space project
   CSA reviewers want a clear link to space missions or space systems. Vague “dual-use” claims are not enough.

2. Ignoring Technology Readiness Levels (TRLs)
   Your application should explain the current TRL and how STDP funding will move it forward.

3. Missing AO-specific rules
   Each STDP AO has its own eligibility and cost-share rules. Do not rely on old calls.

4. Overestimating commercialization readiness
   STDP is for technology development, not market launch. Keep your project focused on technical progress.
