About ARIDO

The Association of Registered Interior Designers of Ontario (ARIDO) is the only professional organization for interior designers in Ontario. First established in 1934, the organisation became 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.

By giving legal standing to the designation of Interior Designer, the government recognizes the high standards of education, training, and formal examination that qualified interior designers meet. The act also safeguards consumers by ensuring that members are fully qualified and possess the most current qualifications. 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.

Any person in Ontario who is not a Registered member of the Association is guilty of an offense if they use the designation Interior Designer or ARIDO.

Since its inception in 1934, ARIDO has grown to become the largest professional group of Interior Designers provincially. ARIDO counts more than 1,800 Registered and Intern interior designers as members, representing all areas of specialty including corporate, residential, retail, hospitality, healthcare and institutional.
