On that point, I'm not sure about an international comparison, but in terms of oversight of national security agencies writ large, whether for terrorist financing or other activities, Canada certainly has a number of review bodies for the RCMP, for CSIS, and for the Security Establishment. As far as FINTRAC is concerned, the only review body that exists is myself, the Privacy Commissioner, and my mandate is limited to determining whether privacy laws are being respected.
For instance, on the question of the effectiveness of the gathering of information and whether it leads to true enforcement action, there is no review body to consider these issues.
