Bill C-2, the government’s proposed lawful access legislation, has been the subject of several prior episodes covering warrantless disclosure of information as part of the new information demand power in Part 14 of the bill as well as some of the surveillance technology capabilities found in Part 15. Those remain major issues, but there is another element of the bill that deserves greater attention, particularly at this moment when the Canada – US relationship is increasingly fraught.  That issue involves mandated data sharing with implications for Canada’s international treaty obligations under the “Second Additional Protocol” to the Budapest Convention as well as the US Cloud Act. Kate Robertson, a lawyer and senior research associate at the Citizen Lab in the Munk School at the University of Toronto, wrote an extensive brief on these issues soon after the bill was introduced. She joins the Law Bytes podcast to talk about a critical Bill C-2 issue that has thus far attracted limited attention.
