Birds of a Feather? Loyalty and Partisanship in the Reformed Canadian Senate

Abstract

AbstractSince 2015, the Canadian Senate has undergone a series of reforms designed to make it more independent, ideologically diverse, and active in the legislative process. We use loyalty scores and vote scaling algorithms to situate the voting behaviour of senators, focusing primarily on the 41st and 42nd Parliaments (2011–2019), the period just before and after the changes, respectively. We find that the reforms have led to a loosening of party discipline across all parties and caucuses but that independent senators appointed under the reformed process are the most likely supporters of the government's agenda. We also find that the Senate has become more willing to use its formal powers.
