ARIDO, (The Association of Registered Interior Designers of Ontario), is the only professional organization for interior designers in Ontario. First established as the Society of Interior Decorators of Ontario in 1934, then Interior Designers of Ontario, the name was changed to the Association of Registered Interior Designers of Ontario in 1984 when the ARIDO Act was passed in the Legislature of Ontario. The act was amended by the passing of Bill Pr6 in 1999 to grant Registered Members who meet ARIDO standards exclusive use of the title Interior Designer in Ontario.
As a professional body, ARIDO's mandate is to regulate the interior design profession in Ontario for the betterment of the profession and in the best interests of the public. ARIDO sets standards for admission into membership, including education and experience standards, Practice Standards, professional development requirements as well as adherence to a Code of Ethics and Practice Standards.
ARIDO counts more than 1,800 Registered and Intern interior designers as members, representing all areas of specialty including corporate, residential, retail, hospitality, health care and institutional. The Association has a total membership of over 3,300 in Registered, Intern, Educator and Student categories.
