In my case, my parents enrolled me in an immersion school simply because, at home, in our community, the school that offered that program was seen as a good school. So that's how it started, without my being involved and almost by chance.
When I was in elementary school, everyone around me spoke French. I thought that all young people spoke French and that it was normal. When I came to high school, I studied in a dual-track school for about six months and realized that, in that school, only one-third of the kids spoke French and two-thirds spoke only English. That's when my world changed. That's why I chose a school where the first language was French, and now, I think I already had this feeling that it was normal, from a young age.
In my mind, I can really see a Canada where it's normal for young people and adults across Canada to learn French and English and to be able to speak one or the other language anywhere. So I think it comes from this experience of suddenly realizing that it's not normal to speak only one language and to want other young people to have experiences like the ones I had at school.
