Standards Development Organization (SDO)

A Standards Development Organization (SDO) is an organization accredited by the Standards Council of Canada (SCC) to develop standards through Canada's national standardization system. SDOs generally work through structured processes that bring together technical experts and balanced groups of stakeholders. Documents developed through the system can be approved by the SCC as National Standards of Canada.

The term is not the same as the Standards Council of Canada itself. The SCC is the national standards body and accreditation authority. It oversees the system, while SDOs are the accredited organizations that write the standards. In Canadian procurement, the term shows up in eligibility rules, in technical specifications and in the work of federal buyers that rely on standards.

How the SCC accredits and oversees SDOs

The SCC accredits SDOs and requires public notification of standards work at specified stages of development. PSPC describes these notification activities as part of how standards are developed in Canada. A National Standard of Canada is a standard the SCC has approved. It can be developed by the Canadian General Standards Board (CGSB) or by another SCC-accredited SDO, as the CGSB's frequently asked questions explain.

Standards development is also separate from conformity assessment. Conformity assessment covers certification, testing, inspection and registration, which determine whether specified requirements are met. An SDO can offer such services, but the two functions are distinct.

The CGSB and the wind-down of its standards work

The CGSB is a federal organization within Public Services and Procurement Canada (PSPC). It has historically been both a standards developer and a conformity-assessment provider. PSPC identifies CGSB standards as supporting procurement in areas such as construction, food and agriculture, protective clothing, textiles, petroleum products and the transportation of dangerous goods. The department's institutional program activities describe this work.

The 2026-2027 departmental plan states that the CGSB is winding down its standards-development and conformity-assessment activities. Other accredited SDOs continue to operate in Canada.

Where SDO appears in Canadian solicitations

Federal buyers use the term in concrete ways. A National Research Council Canada advance contract award notice required the interested association or company to be an SDO accredited by the Standards Council of Canada. The notice on CanadaBuys named CSA Group as an accredited SDO able to provide the required services.

The SCC has also run its own calls for proposals. One described SDOs as participants in Canada's national standardization system and contemplated a contract between the SCC and a selected applicant for standards-related work. CanadaBuys also carries procurement content created by the Canadian Accessibility Standards Development Organization, which operates as Accessibility Standards Canada.

The NATO usage of SDO

In NATO terminology, the abbreviation SDO is listed as Standards Developing Organization in the APD-1 terminology document. NATO's Standardization Office coordinates NATO standardization activities and supports the development and administration of NATO standardization agreements (STANAGs). Details are on the NATO standardization page. Bid teams on defence work should read the abbreviation in the context of the solicitation.

What an SDO requirement means for your bid

An SDO reference in a solicitation can mean one of three things:

• Eligibility: your organization must itself be an SDO accredited by the SCC, as in the NRC notice.
• Technical compliance: your goods or services must meet a standard developed or maintained by an SDO, where the solicitation incorporates that standard. A standard that is normally voluntary can become mandatory when it is built into a regulation or procurement scheme.
• Evidence: you may need to show accreditation, certification, testing or conformity with the specified standard. The exact wording of each solicitation sets the requirement.

Read the mandatory criteria closely, identify which of the three applies, and confirm the current version of any named standard before you submit.
