The Association of Registered Interior Designers of Ontario (ARIDO) is your connection to qualified, experienced, and innovative registered interior designers.

ARIDO protects Ontarians to ensure every person using the title ‘interior designer’ is qualified. In accordance with the Ontario Titles Act, an individual cannot use the title ‘interior designer’ unless they are a registered member with ARIDO.

Why should I hire a registered interior designer?

Registered interior designers have completed the necessary technical education and passed the required exams to meet ARIDO’s rigorous standards for membership.

Once qualified, registered interior designers must keep their knowledge updated through professional development seminars focused on topics including the Ontario Building Code, accessibility, sustainability, building and mechanical systems, inclusivity, etc.

How do registered interior designers become qualified?

They must graduate from an accredited 4-year Bachelor of Interior Design program. They must complete an extensive supervised work experience program under a qualified practitioner. Finally, they pass a rigorous 3-part practical exam which includes building code knowledge.

Everyone benefits from good design…hire a registered interior designer.

A: As a registered interior designer, I’ve been able to have an impact on our local community as we directly influence how people interact with the interior environment.  I’ve designed spaces in Ottawa and beyond with an inclusive approach.
