Yes, we have seen extraordinary progress among anglophones in the past 30 years when it comes to bilingualism. That's for sure. I'm talking here about French as a second language. Around 85% of young anglophones say they can speak French. I'm not talking about the quality of the French they speak, but the fact that they can communicate in French.
In my opinion, the willingness of anglophones to learn French is quite substantial. In the school where my daughters are in immersion, the demand was so high among anglophones that we had to wait for 36 hours to enrol. I think the willingness is there and it's largely due to Bill 101. Apart from its coercive dimension toward immigrants, which we aren't necessarily going to get into now, it lets Quebec anglophones know they are expected to speak French, and that it's important to speak French in order to live in Quebec.
