Who is the COS-SCO?
The Canadian Ophthalmological Society (COS) is the national, recognized authority on eye and vision care in Canada. As eye physicians and surgeons, we are committed to assuring the provision of optimal medical and surgical eye care for all Canadians by promoting excellence in ophthalmology and by providing services to support our members in practice. Our membership includes over 1,149 ophthalmologists which includes 220 ophthalmology residents. We work collaboratively with government, other national and international specialty societies, our academic communities (ACUPO), our provincial partners and affiliates, and other eye care professionals and patient groups to advocate for health policy in Canada in the area of eye and vision health.
