I have one last comment to make.
You spoke of the census. Since the Official Languages Act is based on the very vague criterion of “where numbers warrant”, we tend to want indicators that increase the number of francophones. More inclusive indicators have been suggested, for example. However, this skews the picture. It would be better to have a more specific criterion and ensure that the "where numbers warrant” criterion is really met, rather than changing the indicators and skewing the picture by influencing Statistics Canada.
