This research note uses a new and comprehensive data set of 22,333 municipal elected positions in 3,363 municipalities across Canada to provide a systematic analysis of women's presence in municipal office. Drawing on findings from cross-national research about women's representation in local governments, we examine whether district type, council size, urban setting, women's workforce participation, and degree of conservatism among voters account for variation in the proportion of women elected as councillors and mayors. We find support for most, but not all, of the relevant factors in previous studies. Urban municipalities and municipalities with at-large and hybrid elections are associated with larger proportions of women mayors and councillors. Ideology also matters: the proportion of women in municipal office is smaller in conservative municipalities. Finally, we find no evidence that council size or women's labor force participation is related to women's representation among mayors or councillors.
