Perhaps I misspoke. In fact, since Bill 101 was passed, wherever we have taken greater control over immigration and immigrant selection, the percentage of language substitutions in favour of French has gradually risen thanks to francization outside Canada.
On the other hand, there has been little improvement in francization here at home. The more we move forward, the smaller the percentage of French-language immigrants outside Canada will be relative to immigrants who are already here. The improvement we have seen in language transfers in favour of French has levelled off. We can see it in the figures: it's about 54% and won't rise much higher than 55% or 56%.
