This book provides an empirical analysis, mapping, and assessment of Canadian right wing extremist (RWE) groups and their conspiracy theories.While the majority of studies on RWE groups focus on American and European actors, this book critically examines conspiracies disseminated by Canadian actors on different online sites and social media platforms. The authors deploy a mapping metaphor to chart the conspiratorial ideas that RWE groups create and share online. The book also examines the infrastructural terrain that supports mainstream and alternative platforms and the dark monetization structures that act as important conduits for this negative messaging. Theoretically, the study is situated within the concepts of dark social movements where dark participation on dark platforms often occurs. A conceptualization of conspiracy theories is developed by exploring four specific aspects: (1) topics, (2) targets, (3) concerns, and (4) actors. This concept is operationalized by applying it to Bit Chute and Telegram. The book also offers a historical understanding of different RWE groups and their ideological positions. In addition, it provides an empirical investigation of Google’s autocomplete feature, Amazon books, the Dark Web, and several other alternative social media sites.It will be of interest to researchers of Canadian politics, conspiracy theories, and the far right.
