Minister, I would simply suggest that you look at the chief statistician's testimony before this committee. I asked him if there is a “master key” that allows for those files to become un-anonymized, where you can actually say whose information it is and link that directly to transactions. He said that there was a capacity at any time, subject to policy.
Minister, to say that the data is going to be anonymized and thus that you can't link it to the original person is false.
