There are several ways to reuse a canvas: (1) You may flip it over and paint on the back. (2) If the original painting is waterbased (acrylic, for example) you can paint directly over it with either acrylic or oil paint. But if the original painting was done using oils, you can only paint directly over it with oils. (3) If you prefer a white ground to start with, you can use a primer called "gesso" and apply it in one or more layers for a fresh start.
Paint on canvas has been incredibly popular for centuries. Many artistic geniuses, as well as less famous artists, have produced work on canvas.
Abstract Expressionism
The Dutch artist Jan Vermeer is known for painting himself into a few of his works. A work by Vermeer called 'The Art of Painting' is a good example. In some of his works there may only be part of an easel or canvas in a refection.
Reduce, Reuse, Recycle and Rethink.
If you are using oil paint because it can attack the canvas then a gesso coat is advisable. If acrylic, because it is non-degradable, you can paint directly onto the bare canvas. I suppose it all depends the quality of fineness or finish of the painting.
