Zusammenfassung:Knowledge regarding the antecedent clinical and social factors associated with maternal death around the time of pregnancy is limited. This study identified distinct subgroups of maternal deaths using population-based coroner’s data, and that may inform ongoing preventative initiatives. A detailed review of coroner’s death files was performed for all of Ontario, Canada, where there is a single reporting mechanism for maternal deaths. Deaths in pregnancy, or within 365 days thereafter, were identified within the Office of the Chief Coroner for Ontario database, 2004–2020. Variables related to the social and clinical circumstances surrounding the deaths were abstracted in a standardized manner from each death file, including demographics, forensic information, nature and cause of death, and antecedent health and health care factors. These variables were then entered into a latent class analysis (LCA) to identify distinct types of deaths. Among 273 deaths identified in the study period, LCA optimally identified three distinct subgroups, namely, (1) in-hospital deaths arising during birth or soon thereafter (52.7% of the sample); (2) accidents and unforeseen obstetric complications also resulting in infant demise (26.3%); and (3) out-of-hospital suicides occurring postpartum (21.0%). Physical injury (22.0%) was the leading cause of death, followed by hemorrhage (16.8%) and overdose (13.3%). Peri-pregnancy maternal deaths can be classified into three distinct sub-types, with somewhat differing causes. These findings may enhance clinical and policy development aimed at reducing pregnancy mortality. Les connaissances sur les facteurs sociaux et cliniques antécédents associés aux décès maternels pendant ou après la grossesse sont limitées. Cette étude a permis de relever des sous-groupes distincts de décès maternels à l'aide des données du coroner fondées sur la population et susceptibles d'étayer les mesures préventives et continues. La revue détaillée des dossiers de décès du coroner a été effectuée pour l'ensemble de l'Ontario, Canada, où il existe un seul mécanisme de déclaration des décès maternels. Les décès qui ont lieu pendant la grossesse ou dans les 365 jours la suivant entre 2004 et 2020 ont été relevés dans la base de données du Bureau du coroner en chef de l'Ontario. Les variables relatives aux circonstances sociales et cliniques des décès ont été extraites de manière normalisée de chaque dossier de décès, y compris les données démographiques, les ren
