The Planet Data CenterLawful access legislation is upon Canadians. Introduced by Minister Toews as ‘with the government or with the child-pornographers’ legislation, lawful access will radically expand the scope of Canadians’ personal information that government authorities can collect without a warrant. Personal information would be turned over to the government under new powers regardless of whether an individual’s actions had violated the Criminal Code. Lawful access powers will be granted to formal policing organizations, including municipal, provincial, and federal police, to Canada’s spy agency, CSIS, and to the Competition Bureau. Since the legislation has been tabled, media and experts alike have been scratching their heads to understand the significance of changes between the previous and current versions of the bill. In a subsequent post, I’ll be writing about how the delimited subscriber information fields that authorities want to access is excessive, and I will demonstrate how these fields will be used and can be abused.

In this post, however, I am taking a step back from the legislation proper. Rather than talk about lawful access, I want to make available a book chapter, written for the Canadian Centre for Policy Alternatives, that unpacks some of the surveillance capacities within Canada’s current telecommunications networks. The chapter, titled “Is Your ISP Snooping On You?” (.pdf) first appeared in The Internet Tree: The State of Telecom Policy in Canada 3.0. Specifically, the chapter focuses on a technology that is popularly called ‘deep packet inspection.’ Canadian network agents, such as Internet Service Providers, have deployed these technologies to manage their networks, throttle some kinds of data traffic (e.g. P2P file sharing-related traffic), and track subscriber usage of the networks. This same technology, however, has significant privacy and surveillance implications, insofar as it examines the depths of a data transmission: it is the metaphorical equivalent of not just looking at a postcard, but examining the photo and colour of ink on the postcard to make decisions about how to deliver/treat the message on the card. It is with these network-based technologies in mind that we should reflect on the significance of expanded police access to digital transmissions.

Why is deep packet inspection significant? Because lawful access in Canada might be understood as ‘level one’ of a three-stage surveillance process. The United Kingdom is arguably at ‘level two’ at the moment, on the basis that it possesses an embedded surveillance culture and infrastructure that sees over half a million requests for ‘transactional’ (i.e. everything but the words/pictures of a postcard) data each year. The third level, also being contemplated in the UK, would see deep packet inspection devices repurposed/installed by law enforcement and national security organizations to monitor, mine, and mediate data transmissions between UK citizens in near-real time. Canada isn’t at level three – we’re not even at level two just yet – but our ISPs have experience with embedding technologies that make level-two and -three scenarios possible. Thus, to understand the potential surveillance trajectory associated with lawful access, Canadians must understand existing Canadian network configurations to recognize that this legislation is the first of many stages, and question whether we really want to start down this path in the first place.
