The Canadian Mathematical Society (CMS) () is an association of professional mathematicians dedicated to the interests of mathematical research, outreach, scholarship and education in Canada. It serves the national community through the publication of academic journals, community bulletins, and the administration of mathematical competitions. It was originally conceived in June 1945 as the Canadian Mathematical Congress. A name change was debated for many years; ultimately, a new name was adopted in 1979, upon its incorporation as a non-profit charitable organization. The society is also affiliated with various national and international mathematical societies, including the Canadian Applied and Industrial Mathematics Society and the Society for Industrial and Applied Mathematics. The society is also a member of the International Mathematical Union and the International Council for Industrial and Applied Mathematics. History 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. Since then the society has expanded its activities to serve K-12 and post secondary students as well as professors and established researchers. Graham P. Wright served as executive director of the CMS from 1979 to 2009, and helped to build up the society's executive office in Ottawa and to develop its web-based electronic services. The Canadian Mathematical Society was to celebrate its 75th anniversary during its 2020 Summer Meeting in Ottawa, Ontario. However, due to COVID-19 pandemic, the meeting was postponed to 2021 Summer Meeting. Publications The flagship publications of the CMS are the prominent, peer-reviewed research journals Canadian Journal of Mathematics, which is intended for full research papers, and the Canadian Mathematical Bulletin, which publishes shorter papers. All past issues except the last five volumes are free to download. Access to the most recent research requires a subscription. In cooperation with Springer Publications, the CMS publishes many text books aimed at a university and academic researcher level. The series is called CMS Books in Mathematics. The CMS publishes ten issues per year of Crux Mathematicorum, which contains problem-solving challenges and techniques suitable for training in secondary school problem solving competitions such as the Canadian Mathematical Olympiad or the International
