Dîner vs Déjeuner

Hi, I live in Québec and I've been here for quite a while now. Whenever people want to refer to lunch here, they use dîner. Déjeuner is used to mean breakfast, and souper is used to mean lunch. The test said I was wrong when I translated lunch as dîner and I understand that since in France it means a completely different mealtime. Just wanted to post this so that others could be aware of the different vocabulary we use in Québec, since it was really confusing to me for a long time.
