What impact do local candidates have on elections in single member district plurality electoral systems? We provide new evidence using data from a large election study carried out during the 2015 Canadian federal election. We improve on the measurement of local candidate effects by asking over 20,000 survey respondents to rate the candidates in their constituency directly. We present three estimates. We find that when all voters are considered together, local candidate evaluations are decisive for approximately 4 per cent of voters. Second, these evaluations are decisive for the outcome of 10 per cent of constituency contests. Third, when models are estimated for each constituency, we find significant evaluation effects for 14 per cent of candidates.
