Concerning your question about language of work, it turns out that the proportion of francophones outside Quebec who indicate that they use French most often at work has remained stable over the past two censuses. On the other hand, in response to the question you mentioned regarding the use of another language, people often give English as their answer.
So when we ask whether people use another language regularly in the workplace, we find a slight increase in the number of francophones who say that they use French regularly. It also depends on the type of work francophones are doing. We know that francophones tend to work in health care, education and certain industrial sectors. So there may be an increase in the use of French there.
