Yes, certainly. The practice recently implemented in Ontario could become a best practice, since it allowed us to collect, for the first time, data on students' country of origin and year of arrival in the country. As a result, we found that 44% of students in Ontario's French-language schools come from immigrant backgrounds. Of course, we already knew this, since we could see that there were many immigrant students in our schools. So, yes, it's possible to get that data. Ontario has done it, but I'm not aware of similar practices elsewhere in the country.
