What determines how Members of Parliament (MPs) and their staff frame their communications with all constituents in their electoral district? Prior research has suggested that constituency operations are one of the last bastions of freedom that MPs have from the full grasp of party discipline in Canada. If this remains true, MP communications with their constituents should reflect the MPs’ background or the constituency context and not their political partisanship. We collected a sample of published newsletters (“householders”) that Canadian MPs’ offices sent to all households in their electoral districts during the COVID-19 pandemic. We supplement our analysis with original insights about householders from a selection of MPs and their staff. Our results suggest that in a system of strict party discipline, the most important predictor of what MPs include in their constituent communications is indeed partisanship. The results inform our understanding of democratic representation, centralized co-ordination and political communication, and the pervasiveness of partisan messaging in Canada.
