Abstract
Measuring relative legislative influence is notoriously difficult, particularly in bicameral systems where two chambers have similar formal powers. Recent changes to the Canadian legislature offer a unique opportunity to understand how an upper house liberated from party constraints impacts that houses’ legislative influence. I leverage an original panel data set matching lobbyist activity to parliamentarian characteristics and responsibilities and, using a difference-in-differences design, compare Members of Parliament to Senators, both independent and partisan. I find that independent Senators receive disproportionately more attention from lobbyists both after the changes and as the independent composition of the Senate grows. This article offers a time-variant measure by which perceived influence can be evaluated and contributes to the extant literature on intercameral relationships, partisanship, the legislative process, and party discipline and cohesion.
