Who runs and is elected is one of the most fundamental questions in political science as it pertains to the issue of descriptive representation. Despite the importance of this issue, until recently there were no longitudinal datasets on candidates in Canadian elections. This article presents two novel datasets including information on all candidates who ran in Canadian federal and Ontario provincial elections from 1867 to 2019. I present how these data were collected and how they can be used to gain new insights. I expect these data will be a valuable resource to Canadian political scientists for both research and teaching purposes.
