The Canadian Orchid Congress (COC), federally registered as a non-profit society, is an association of Canadian orchid societies that is dedicated to serve the Canadian orchid-growing public. The COC represents affiliated societies and their members on Canada wide issues. This is achieved by a newsletter, a website, speaker tours, an annual conference devoted to the advancement of knowledge and appreciation of orchids in Canada, and other activities that can be shared by the member societies. There are some twenty-five Canadian orchid societies that are members of the Canadian Orchid Congress.

The Orchid Society of Nova Scotia is a hobby organization dedicated to the cultivation, study, conservation and enjoyment of orchids in Nova Scotia, Canada.
