Canada published its first accessible plain language standard on International Plain Language Day, October 13, 2025. The standard is called CAN-ASC-3.1:2025 – Plain Language. It is the product of more than 5 years of hard work by Accessibility Standards Canada (ASC) and its Technical Committee for Plain Language.
Why create a plain language standard?
ASC has 2 goals:
- to create a barrier-free Canada by January 1, 2040
- to contribute to the identification and removal of existing barriers and to prevent new ones
ASC accomplishes these goals mainly by developing accessibility standards, but it also funds accessibility research and shares information related to accessibility.
CAN-ASC-3.1:2025 – Plain Language was one of the first standards ASC published. To date, the organization has published 8 standards with another 39 in development. This shows the importance that ASC gives to plain language.
Dino Zuppa, Chief Executive Officer of Accessibility Standards Canada, had this to say about plain language and the standard:
“Plain language is more than good writing. It’s a matter of accessibility and inclusion. It helps people make informed decisions, access services, and participate fully in their communities. This new standard gives organizations the tools to remove barriers and ensure their information truly serves everyone.”
Who is the standard’s intended audience?
All ASC standards, including the plain language standard, are intended for use by federally regulated entities. This includes the following sectors:
- Government of Canada departments and agencies, including federal courts
- Industries and workplaces that the Government of Canada regulates, including:
- Banking
- Broadcasting and telecommunications
- Crown corporations like Canada Post
- Transportation by road, rail, water, and air
How does the standard compare to the USA Plain Writing Act of 2010 and ISO 24495-1:2023 – Plain Language Part 1?
The Canadian standard is much longer and more detailed than either the Plain Writing Act of 2010 or the first ISO plain language standard.
The following table shows the major similarities and differences between each of them:
| CAN-ASC-3.1:2025 – Plain Language | Plain Writing Act 2010 (USA) | ISO 24495-1:2023 – Plain Language Part 1: Governing principles and guidelines |
| Uses an adapted version of the *IPLF’s definition of plain language | Uses the term “plain writing” not “plain language” | Uses the IPLF’s definition of plain language |
| Publicly available and free | Publicly available and free | Available for a fee |
| Applies to Canadian federally regulated entities | Applies to Federal agencies in the USA | Applies to anyone who purchases the standard and wants to use it |
| Includes examples and strategies to help users apply the standard | Leaves it up to government agencies to train employees in plain writing as defined in the Act | Does not include examples or strategies to help users apply the standard |
| Focuses on many formats of communication including audio, video, and sign language | Focuses on writing and documents | Focuses on text, printed and digital |
| Directly addresses accessibility and barriers to finding, understanding, and using information | Does not address accessibility or barriers | Does not address accessibility or barriers |
| Voluntary until the minister responsible makes all or part of it mandatory through regulation | Mandatory | Voluntary |
*IPLF stands for International Plain Language Federation
Includes examples and strategies
The Canadian standard is the only one that offers examples and strategies to help the user create a plain language communication. For example, Clause 10.2 Learning about the intended audience states the following:
- Throughout the development of your communication, you shall consult and engage with the intended audience about their information needs and any barriers they face except as identified in Clause 10.2 b). The following are possible strategies:
- create an accessibility advisory committee to review communications;
- co-create communications with members of the intended audience;
- consult with people from your intended audience at key points during the development of the communication; or
- have representatives of the intended audience evaluate the communication before publication. See Clause 11.
Further, the Canadian standard defines “communication,” “design,” and “intended audience.”
Can the standard be enforced?
Currently, the standard is voluntary. Anyone can use it to improve their communication. But, since the standard is not yet mandatory, it is not being enforced. That could change in the future. Part or all of the standard could become mandatory for federally regulated entities. This would happen under the following circumstances:
- The minister responsible for the standard recommends that it become part of the regulations of the Accessible Canada Act.
- Parliament agrees with the recommendation.
In most cases, standards are edited and part or all become regulation.
Will the standard be updated?
ASC reviews and revises all its standards every 5 years or earlier if needed. The process has already begun. On each page of each published standard is a “Report a problem on this page” button. Readers can click up to 6 pre-selected problems and add additional information in a comment box.
In addition, anyone can email ASC to provide feedback on its standards.
Are other writers using the standard?
Because the standard is freely available on ASC’s website, anyone in the world can use it. And, because you don’t have to buy the standard or have a licence to use it, there is no way to track who is using it. Still, at least one organization is making it part of their digital communications design system: Desjardins, one of Canada’s largest financial institutions.
Desjardins was one of the standard’s earliest adopters, following its progress since ASC published the standard’s first draft. Véronique Blais, Desjardins’ Senior Public Relations Advisor, said that the company is producing a new digital content guide. The new guide will reflect both the standard and its own UX writing methods. This will ensure the accessibility of their communications.
“Communicating in a clear, inclusive and accessible manner is … essential to supporting everyone we serve on our digital platforms, regardless of their profile or challenges,” Blais said.
Where can people learn more about the standard?
ASC is actively promoting the standard, first by announcing its publication on social media on International Plain Language Day. Since then, it has promoted the standard in every province and territory in Canada.
We have seen how Desjardins is implementing the standard. Perhaps others will announce their implementation as well.
Members of the Technical Committee have spoken about the standard at the Brussels Plain Language Experience 2025 last November. They also spoke at a Plain Canada Clair conference and an Editors Canada webinar in January. It is also being discussed in blog posts like this one, and on at least one podcast.
