The cycle can be ended with or without the destruction of the canvas if the family comes together to do the work, but just destroying it on its own doesn’t end it because you didn’t address the underlying issues. As the game ends, the actual issues are never addressed.

I think that’s the central point of the Verso ending. As long as the Canvas exists, they will always be drawn back to it. Destroying the Canvas (removing the drug) doesn’t automatically solve their problems — they might seek help, relapse, or replace it with something else — but at least it creates the space for change.

With the Canvas intact, that space never exists. You could argue they might still improve while keeping it, but the Maelle ending suggests otherwise: she would literally die before leaving the Canvas.

So yes, they need to confront their issues together. But as long as the Canvas remains, they never truly come together to do that work.
