We are a volunteer run, Canadian registered non-profit corporation whose purpose is to further the study of roses, to promote the cultivation thereof, to discover and disseminate knowledge of the conditions favourable to the culture of roses throughout Canada.

The Rose Society of Ontario was founded in 1913 in Toronto by a group of dedicated ladies. Men were admitted in 1918, and by 1954 membership had spread across the country. To reflect that fact our name was officially changed to the Canadian Rose Society.
