Government and law enforcement justifications for warrantless access to Internet subscriber information has long been defended on the grounds that the information being demanded carries little privacy interest. The go-to claim was always that it was “phone book information”, a reference to the largely discontinued practice of printing an annual public directory that included name, address, and phone number. The problem with that argument was that the information at issue included data points such as IP addresses and device identifiers, which could be used to track users and monitor online activity without a warrant. Moreover, linking a specific user to a specific IP address or other identifier effectively unlocks the door to potentially very sensitive information that is otherwise unavailable. Indeed, there is a reason that law enforcement logged over a million warrantless requests per year for basic subscriber information prior to the Supreme Court shutting down the practice.

Privacy At Risk: Government Buries Lawful Access Provisions in New Border Bill
The government yesterday introduced the Strong Border Act (Bill C-2), legislation that was promoted as establishing new border measure provisions presumably designed to address U.S. concerns regarding the border. Yet buried toward the end of the bill are lawful access provisions that have nothing to do with the border. Those provisions, which raise the prospect of warrantless access to information about Internet subscribers, establish new global production orders of subscriber information, and envision new levels of access to data held by electronic service providers, mark the latest attempt in a longstanding campaign by Canadian law enforcement for lawful access legislation. Stymied by the Supreme Court of Canada (which has ruled that there is a reasonable expectation of privacy in subscriber data) and by repeated failures to present a compelling evidentiary case for warrantless access, law enforcement has instead tried to frame lawful access as essential to address everything from organized crime to cyber-bullying to (now) border safety. Much like the government’s overreach last year on online harms, Bill C-2 overreaches by including measures on Internet subscriber data that have nothing to do with border safety or security but raise privacy and civil liberties concerns that are bound to spark opposition. This post provides the background on lawful access and an overview of some Bill C-2’s provisions with more details on key elements to come.
The Law Bytes Podcast, Episode 231: Sara Bannerman on How Canadian Political Parties Maximize Voter Data Collection and Minimize Privacy Safeguards
As the 2025 federal election passes the midway point, it is increasingly apparent that the federal political parties are not only battling for votes, but also for data. Canadians may not see it but political parties are data machines anxious to collect and use as much data about potential supporters as possible. Sara Bannerman is the Canada Research Chair in Communications Policy and Governance at McMaster University. She has been examining the privacy concerns with Canadian political parties for years, highlighting the disconnect between the expectations of Canadians and the reality on the ground. She joins the Law Bytes podcast to discuss Canadian political party privacy – or lack thereof – and explains the role that data plays in the modern political party machinery.
The Law Bytes Podcast, Episode 228: Kumanan Wilson on Why Canadian Health Data Requires Stronger Privacy Protection in the Trump Era
The craziness of the Trump administration relationship with Canada was on full display this past week as seemingly every day involved some form of policy change on tariffs – first on, then slightly delayed for some goods, then slightly delayed for more goods and by week’s end threats of new tariffs. Given the uncertainty, I recently co-wrote an op-ed in the Globe and Mail together with Dr. Kumanan Wilson that sought to put the spotlight on another issue that could come to the fore if the economic battle moves beyond tariffs to other issues. In this case – privacy, data localization and health data.
Dr. Wilson is a specialist in General Internal Medicine at The Ottawa Hospital, Chief Executive Officer/Chief Scientific Officer, Bruyère Research Institute, a Professor and Faculty of Medicine Clinical Research Chair in Digital Health Innovation at the University of Ottawa and member of the University of Ottawa’s Centre for Health Law, Policy and Ethics. He joins the Law Bytes podcast to discuss why we should be paying attention to health privacy, AI and the location of our data.
Canadian Health Data Requires Stronger Safeguards With Lost Canada-U.S. Trust
With today’s implementation of tariffs on both sides of the Canada-U.S. border, the level of mistrust between our countries has grown, whether urgent calls to “Buy Canadian” or boos and catcalls at the playing of the American national anthem. Should we continue down this path, Mr. Trump will surely seek to exploit more of Canada’s potential vulnerabilities. Last week, I co-wrote an op-ed with Kumanan Wilson on one such vulnerability: our health data, whose protection has yet to attract much attention but which could emerge as an issue.
