Société mathématique du Canada
The Canadian Mathematical Society (CMS) was originally conceived in June 1945 as the Canadian Mathematical Congress. The founding members hoped that "this congress [would] be the beginning of important mathematical development in Canada". Seeking to end confusion with the quadrennial mathematical congresses, a name change was considered for many years. Finally, upon its incorporation as a non-profit, charitable organization in 1978, a new name was adopted - the Canadian Mathematical Society.
