The Canadian party system experienced a period of remarkable transition between 2006 and 2015, with the New Democratic Party (NDP) and Liberals trading places as the main competitor to the Conservatives. While national-level explanations are often used to explain this volatility, William Cross's research has shown that local association revitalization played a central role in the Liberals’ 2015 resurgence. This article examines the relationship between NDP local spending and success between 2006 and 2015. It shows that the NDP was consistently outspent by its opponents overall but that it often had a spending advantage in marginal ridings. As a result, this article finds little evidence that the NDP's local spending disadvantage cost the NDP seats, even though it finds a positive correlation between NDP local spending and NDP vote share.
