As for the young people who come to Alberta, I would say there are two categories, depending on the work they do.
Those who work in the trades can do that work, even if they don't speak English very well. Often, their employer assigns them to a supervisor who speaks both languages, so that that person can give them work instruction in the language they understand best. In spite of everything, those young people will tend to get assimilated, because they won't see any benefit in speaking French.
I'll go back to the question put by your colleague about the interest the province has in francophone immigration. We have taken steps to offer English classes in francophone environments so that these people, even if they learn English, stay in touch with the francophone community. We have already begun taking steps to do that, but this has not been successful up till now.
I apologize, but I forgot the topic of your second question.
