For any non-Canadians reading this, understand that Canadians have a very different relationship with CSIS than say Americans do with the NSA or Brits with GCHQ. We have not seen the bulk use of this data for purposes of general law enforcement. It isn't being used to nab drug dealers or child pornographers. CSIS is rather oldschool in it's approach: intel assets are for intel purposes, not law enforcement. At least that is what we have seen so far. The trust has yet to be broken as it has elsewhere.
