Another year of COVID-19 meant another virtual meeting but the Canadian Mathematics Education Study Group/Groupe Canadien d'Étude en Didactique des Mathématiques (CMESG/GCEDM) made the best of the situation and found ways to learn together and share connections. Having learned a lot from the 2021 virtual meeting, the executive was able to once again offer a virtual program that, although reduced from the normal offerings, ensured an opportunity for spirited discussions, meaningful learning, and celebrating the newest members. The 45th annual meeting took place May 27-29, 2022. These proceedings contain one plenary lecture, six working groups, and ten new PhD reports. Seventeen papers are included in these proceedings--two papers are written in both French and English; three papers are written in French; and the remainder are written in English.
