Abstract

This preview chapter seeks to contribute to the growing debate in Canada over mass state surveillance by shedding light on key aspects of Canada’s Communications Security Establishment (CSE) domestic internet surveillance activities. Drawing mainly on the Snowden documents, it argues that there are good reasons to suspect that CSE is routinely intercepting the internet communications of millions of Canadians. A further exploratory analysis of Canadian internet traceroute data estimates where and with which carriers CSE is most likely to capture internet traffic. This analysis shows that by accessing the main switching centres of a handful of leading telecom providers (e.g. Bell, Rogers, Shaw, Telus) CSE could surveil a large fraction of Canadians’ internet communications by establishing interception facilities within a few key cities (notably Toronto, Montreal and Vancouver). This chapter draws attention as well to CSE’s excessive secrecy about its domestic internet surveillance capabilities and concludes by calling on CSE to meet its obligations to respect human rights and democratic norms by being more transparent and accountable to Canadians.
