Canvas has graphics property, which can be used to draw on:

var g:Graphics = canvas.graphics;
g.moveTo(10, 10);
g.lineTo(20, 10);

When shapes are moved, call g.clear() and draw lines with new coordinates. Reference: Graphics

Lines will appear under children of canvas. If you need to draw something over them, then you need something above your Canvas - maybe another Canvas positioned over first.
