Saint-Louis-du-Ha! Ha!'s motto is Solidaire dans le Labour, French for Interdependent in Work. Its current mayor is Donald Viel.
There is an explanation for the town's name: The founders, in 1873, would have sighed an "Ah, ah!" of admiration on discovering nearby Lake Témiscouata. Then, say the locals, the scribe probably misspelled the expression.
