There's no limit, then, to the reach of the government in using this technology in spying on Canadians. Microsoft—lots of folks use Microsoft to store their documents—Dropbox and Google are all cloud-based. People store family photos in there. They store personal correspondence in there. They store confidential and private medical information in there.
Would it ever be appropriate for the government to use the guise of saying, “Well, it's a government device, and you once logged into your cloud-based account using that device. Therefore, we now have unfettered access to that”? Is the only measure after the fact: what they looked at and, “Oh, well, we only took certain things”?
Once they've viewed the information, the privacy of the employee has been violated. That Canadian's privacy has been breached. Is it ever appropriate?
