Thank you for your question, Ms. Chabot.
There is actually extensive literature on the issue. In Quebec, there have been numerous partnerships among universities, the health industry and the community to seek out evidence and to do what is best.
There is a website called Infos-accessibles, which provides strategies for that purpose. It provides references on good practices to simplify texts, and it provides examples on good writing practices and those that aim to use images to support the message.
So it is extremely important to keep in mind the condition of individuals with an intellectual disability. From 1% to 3% of people are living with an intellectual disability—so about 500,000 Canadians.
Even without a diagnosis of intellectual disability, many people have what is referred to as low literacy. By keeping in mind that many struggle to interpret the information provided to them, the authorities would be helping those people out. Especially during COVID-19, information is coming from all over the place. One day, it's white, and another day, it's black, and that is normal. It's an inexact science, and an attempt is being made to explain it.
To answer your question, Ms. Chabot, there are indeed websites for an organization or a country that wants to seek out content and know how to make its communications accessible. The website Infos-accessibles is one good example of that.
