Canada’s decision to sign the UN Convention against Cybercrime, described as a treaty with "strong human rights safeguards," has raised concerns due to its broad surveillance and evidence-sharing powers. Initially opposed in 2024, the government signed in July 2026 without addressing prior criticisms. The convention, pushed by Russia, allows cross-border data collection for any "serious crime" (offenses punishable by four+ years), risking misuse under repressive domestic laws.

Over 20 Canadian groups urged against signing, warning it could enable repression of journalists, activists, and diaspora communities. Critics note the treaty lacks safeguards like judicial oversight, permitting gag orders, and omitting a political offense exception. Canada’s prior absence at the 2024 signing ceremony and its engagement with Russia and China during negotiations further complicate the move.

The treaty’s marginal value for Canada is questioned, as existing frameworks like the Budapest Convention already cover key allies. Lawful access legislation (Bill C-22) and the absence of public consultation deepen concerns. Experts argue the signing prioritizes unclear benefits over risks, leaving doubts about Canada’s cybersecurity strategy.
