Depending on what exactly you want to do, the solution may be different.
Do you want to delete the last line but keep the previous drawing?
Or dou you want to make a rubber band.
Enter 'canvas undo' in the search box, and you get answers, I have not test all the solutions.

You could also do it with Canavas1.DrawColor(Color.Transparent).
