Red Shirt Day (of Action for Accessibility and Inclusion) is a day when people across Canada come together and wear red in schools, workplaces and spaces everywhere in order to create a visible display of solidarity: to show their support for persons and families who are living with disabilities, celebrate the achievements of people living with disabilities, and to pledge their commitment to help create a fully accessible and inclusive society that honors and values the contributions of people of all abilities in all aspects of life in Canada.

Red Shirt Day takes place on the Wednesday of National Accessibility Week each year. In 2021, Red Shirt Day will take place on Wednesday, June 2nd, and National Accessibility Week is from Sunday, May 30 to Saturday, June 5.
