Thank you, Mr. Chair, for the question.
Depending on the objective of the study or the research we do, one source for us would be to look at the census data, which collects lots of information around language spoken at home. Again, depending on the objective, and the integration of data, we maybe could derive at-risk populations. That's one example.
I do want to say that we collect a large number of surveys. We also have access to administrative data, whether it's from ESDC, CRA or the provinces and the territories. On a regular basis, we do integration of data because the power of data is there when you combine it. We do that respecting confidentiality and the privacy of the information. We also do that through a secure environment, and we use different statistical methods to combine the information.
