this is true for a lot of other rivers as well. I think the distinction is whether the bed is still somewhere near the old position, then it is not considered a canal, while a waterway that cuts through the natural topology and diverts water into areas where there wouldn’t normally be, or in directions it wouldn’t normally flow, then it is clearly a canal (intended on the scale of the waterway, not just locally).
