That's an excellent question.
We definitely have programs to encourage this, such as French courses for residents of London. The focus here is on young elementary and high school students. Some tools have also been developed for adults. You have no doubt heard of the Mauril app, which is free and accessible to all Canadians. The application focuses on Canadian cultural products in connection with second official language instruction. After that, I would encourage every city in the same situation as London to build bridges with francophone cities in Quebec, or with other Canadian cities interested in the francophonie.
