De-identified data.... Data is stored in bits and bytes or ones and zeros on a medium. When you delete a file, Minister—and you don't have to have a Ph.D. in computer systems technology or computer science to know this—all you delete is the link on the file allocation table that references the data on the stored medium. Anybody with any skill whatsoever—anybody under the age of 35 today—could probably go back and look at any particular data point on a data medium and re-identify data. It's not a complicated thing to do.
Minister, what assurances can you provide to this committee and to Canadians that their information cannot be re-identified?
