The main objective of this research is to understand the experiences of Canadian Muslim civil-society organisations that seek to influence counter-terrorism legislation and policy. I use the public debate surrounding the enactment of one of the most significant pieces of Canadian counter-terrorism legislation since 2001, the 2015 Anti-terrorism Act, Bill C-51, as a case study. The paper draws on growing evidence that public cooperation with the state in counter-terrorism policing increases when the process by which counter-terrorism policies and laws are made are viewed as fair. The main research question examines the extent to which the process of enacting Bill C-51 met the procedural fairness standards in relation to voice, neutrality and respect. There is a particular focus on voice, with further questions of how and where voice is articulated.
