Oh, I'm sure they collect it, but they just don't want to share it. The only way this person—a Globe and Mail telco reporter, ironically—was able to access it was to file an access to information request to get that information.
PIAC, the Public Interest Advocacy Centre, has requested it multiple times, and the CRTC has written letters saying that no, this is not in the public interest or that this would compromise, potentially, the security of individuals and security in the telcos.
It's an absurd argument, in my opinion, for defending the telcos.
