Some of the systems are not new, but some have to be rebuilt for every census because our questionnaires change. Then we have to make the necessary corrections to those systems to reflect the fact that the questionnaires have been updated.
A lot of data is handled and transferred to ensure that we ultimately get high-quality data. There are several stages: compilation and findings for Canadians, certification, and so on. Most of those stages are automated. Where that is impossible, they are performed manually. Consequently, parts of the work are indeed done manually.
In a case such as this, since Canada has 5,000 municipalities and tens of different variables must be cross-referenced, we will look for automated ways to do that cross-referencing. If it were done by hand, it could take us years.
We also try to see whether we can detect anomalies in the data before releasing them. Here again, once the lesson has been learned, we will make those systems more rigorous and smarter to prevent the situation from reoccurring.
