Abstract To enable new research on local ideology and representation in Canada, we construct a latent measure of the policy ideology of 37,500 Canadian Election Study respondents using 56 policy-relevant questions and then use multilevel regression and poststratification to estimate the average ideological position of each of Canada's 338 federal electoral districts and 250 largest municipalities. We use these local ideology estimates to examine ideological representation in Canadian municipal politics. Combining our municipal ideology estimates with elite survey data from more than 900 Canadian municipal politicians, we find evidence of a strong relationship between mass and elite ideology. This relationship is consistent across differing municipal population sizes and institutional structures. We conclude with additional detail on our publicly available individual and aggregate measures and describe their potential uses for future research on ideology and representation in Canadian politics at all levels.
