This article reports the results of a survey examining Canadians’ attitudes about political parties’ collection of personal information. Datified campaigning brings concerns about surveillance, divisiveness, digital redlining and elector autonomy. This article asks whether awareness of parties’ data collection practices affects willingness to engage with campaigns. We find (1) that respondents are not fully aware of political parties’ data collection practices, (2) that awareness of parties’ collection of personal information may reduce electors’ willingness to interact with political parties online, (3) that those who are more aware of these practices report higher levels of concern about them and that those who do not think that parties’ collection of personal information is important to the democratic process also report higher levels of concern, and (4) that new legal measures to regulate how political parties collect and use personal information are supported by respondents.
