About OAO

The Ontario Association of Orthodontists (OAO) is the voluntary organization of certified orthodontic specialists in Ontario. Our mission is to serve both the providers and the recipients of specialist orthodontic care in the province.

We are the official voice of Ontario orthodontists to organized dentistry, educational institutions, professional licensing bodies, the public and government. Every OAO member is a certified orthodontic specialist, and we help patients make informed decisions about orthodontic care through education and information.

What we do

Inform patients

We help the public understand orthodontic care and why seeing a certified specialist matters.

Advocate for the specialty

We represent Ontario orthodontists to the RCDSO, ODA, AAO, CAO, GLAO and government, and act when specialty credentials are misrepresented.

Support learning

Twice-yearly business meetings, Core 1 lectures and a biennial scientific session keep members up to date.

Connect colleagues

We bring Ontario’s orthodontists together to share knowledge and support one another.
