R3 has some similarities with another Movement for Catholic youth in French Canada called "La Flambée". One of these similarities is the fact that it is usually in pairs with "La Relève", a movement for teens (14-18) serving as an antechamber to R-cube. The same way as La Flambée is paired with "L'Étincelle". The similitude between "R3-La Relève" and "La Flambée-L'Étincelle" makes it so that in most dioceses where the French-speaking Cursillo Movement exists, you will find either one of these tandem, but seldom both at the same time.
R3 (pronounce R-cube) is a Catholic Movement for young adults, found in many French-speaking dioceses in the eastern part of Canada, specially in the dioceses of Gatineau/Hull, Joliette, Mont Laurier, Rimouski, Sherbrooke, St-Hyacinthe & Valleyfield. It has its roots in the Cursillo Movement.
The "R" in R3 refers to the French word "Rencontre" meaning "Encounter". Hence "R-cube" stands for the triple encounter experienced during their weekend as in the cursillo :
After the weekend, "R-cubists" get together regularly to deepen these encounters and help each other to respond to the invitation of God's love
