The ideological and issue positions of parties are known to shape citizens’ political attitudes and voting behaviour. One important way to obtain estimates of parties’ positions is to ask experts to place parties on salient ideological dimensions. The Chapel Hill Expert Survey (CHES) has been collecting such estimates for democracies in Europe and elsewhere. CHES Canada adds to this project by providing estimates of party positions and characteristics of Canadian federal parties and provincial parties in Ontario and Quebec. This note introduces this new data source, clarifies how the data were collected and illustrates how the data can be used to (comparatively) study party politics in Canada.
