Policy versus practice: Third party behaviour in Canadian elections

Third party campaigners are widely noted to have the power to change the landscape of an election. Yet, in Canada, we know little about whether there is consistency behind third parties' motivations, expectations and strategies, or how these motivations parse with those of the legislators who are attempting to regulate their behaviour. This article explores these factors using data from Canadian federal elections from 2004 to 2015. Merging qualitative interviews and survey data of third parties with quantitative evaluations of third party and political party campaign spending, we assess whether the strategic motivations of third parties reflect the intentions and design of campaign policies that regulate their actions. The United Kingdom regulatory regime is briefly reviewed as an example of an alternative policy approach.
