Abstract: Through mainstream discourses that infuse all components of society, settler superiority is naturalized in Canada. This process occurs at the expense of Indigenous peoples who continue to be displaced from the land, which is conceptualized as a ‘resource’. Despite the seemingly static nature of settler colonialism, its hegemony is both contested and reinforced through the participatory social space of Instagram. Though it is primarily known for its aesthetic and visual communication properties, Instagram’s visuality contributes substantially to public discourse, enabling resistant and political expressions around specific issues. Using data collected from Instagram, this article maps the social life of Canada’s controversial Trans Mountain pipeline issue, as it develops under medium-specific affordances. Around the Trans Mountain pipeline issue, hashtags and imagery mutually inform one another on Instagram, connecting highly located and temporal experiences with national policies, as users performatively challenge and reinforce social relations as they exist under settler colonialism.
