It is probably a different survey from the one carried out by Statistics Canada. I know for a fact that the Santé en français research network undertook many surveys on that topic. Researchers from the network also carried out many qualitative inquiries in which they ask people to specify the offer or availability of services. I know that those do not fall under Statistics Canada; that is why I cannot provide an opinion on them. Nor am I familiar with the way other questions were formulated.
As I was telling you, we often come across surveys that contain subjective questions. Yet, there are ways to ask questions so that the credibility and objectivity of answers are reinforced.
