There was no surveillance, Mr. Villemure. I will repeat in French what I said in English earlier. The data is anonymized and aggregated. It is impossible to have information of a private nature, and it is obvious that this has not been requested. You are an ethicist and a statistician who is not only reputable but also competent enough to understand that aggregated and anonymized data cannot be used to identify people.
