In recent years, Indigenous peoples have lead a number of high profile movements fighting for social and environmental justice in Canada. From land struggles to struggles against resource extraction, pipeline development, and fracking, land and water defenders have created a national discussion about these issues and successfully slowed the rate of resource extraction. But their success has also meant an increase in the surveillance and policing of Indigenous peoples and their movements. Andrew Crosby and Jeffrey Monaghan use the Access to Information Act to interrogate how policing and other security agencies have been monitoring, cataloguing, and working to silence Indigenous land defenders and other opponents of extractive capitalism. Through an examination of four prominent movements -- the long-standing conflict involving the Algonquins of Barriere Lake, the struggle against the Northern Gateway Pipeline, the Idle No More movement, and the anti-fracking protests surrounding the Elsipogtog First Nation -- they raise questions regarding the expansion of the security apparatus, the normalization of police surveillance targeting social movements, the relationship between police and energy corporations, the criminalization of dissent, and threats to civil liberties and collective action in an era of extractive capitalism and hyper surveillance.
