Performances, guided tours, candlelit storytelling, theatrical performances, immersive experiences and family-friendly activities will make this festive weekend a memorable experience for all.

And to bring the celebrations to a close: the unveiling of “Vous êtes Onex” (You Are Onex), a collective photographic mural created as part of Inside Out, the international participatory art project founded by artist JR. This artwork will celebrate the faces and diversity of Onex’s residents.
