What metadata could include might be a question you would want to ask CSE for the details of.
Metadata can include identity information. Not all metadata necessarily carries a privacy interest. That is what we're looking for when we're conducting a review of CSE's activities. It could involve an email address, a telephone number, an IP—internet protocol—address, and other things. Metadata has evolved over the years, and may evolve in the future. We want to make sure that CSE's collection of metadata, which can include metadata with a privacy interest, has all the safeguards applied to it as with any other information or intersection of private communications that they are allowed to do under ministerial authorizations. That's what we're focused on.
The commissioner, I believe, made reference earlier to a recommendation that he made to the Minister of National Defence that CSE be given explicit authority to collect, use, retain, and share metadata.
