L’union fait la force is a French language game show airing weekdays on Radio-Canada. It is hosted by Patrice L'Ecuyer.

The content of the show are primarily "quizzes" that pertain to words in the French language. The quizzes range from everything from guessing words all the way up to Pictionary-style games.

The game consists of two teams, made up of four competitors and supporters behind them. The team represents the organization. The teams compete for points via the abovementioned "quizzes". The team that earns the most points wins a prize of C$1,000.

Tuesday and Thursday editions of the show include a special round, La petite école, in which contestants answer questions written by elementary and secondary school students, with each question pertaining to a grade level.
