Yes, on the French territory, meals are :
- breakfast : petit déjeuner
- lunch : déjeuner
- after school snack : goûter (kids)
- dinner : dîner (@8:00pm)
- supper : souper (later at night).
Please note that verb "déjeuner" can be used for breakfast and for lunch, but verb "petit déjeuner" is incorrect as a verb.
There's much discussion on the difference between France and Quebec but I'm from Ontario, Canada and this is what we were taught in school (French Catholic not French immersion). (I haven't mastered the keyboard accents so please excuse me)
- Dejeuner - breakfast - in the morning
- Diner - lunch - around 12 p.m.
- Gouter - snack - anytime but more likely during the afternoon
- Souper - supper - around 5 p.m.
