I mentioned earlier that, in the national census tests of 1993 and 1998, Statistics Canada conducted testing on the language of instruction. The results were not perfect and led to other questions. We have formed partnerships with the federal government departments on an ongoing basis. It was actually as a result of the census tests that discussions ensued for Statistics Canada to conduct a survey on the vitality of official-language minorities, such as the one conducted in 2006, specifically to address that need. Clearly, there were a lot more questions. There were various themes related to the languages in use in the public space. It was one of the main objectives. That's how Statistics Canada was able to answer the questions related to section 23.
