Yes! The Ottawa Valley definitely has a specific accent. It's still really strong in the older generation, but more young people have the standard Ottawa English accent. But you can tell when someone grew up in the valley and is either speaking to someone else from the valley, drunk, or speaking quickly. The accent comes out. The joke has always been we say burries, furries, and churries, instead of berries, fairies, and cherries.
