This worked: myCanvas.removeChildAt(myCanvas.getChildIndex(event.mouseTarget));
and myCanvas.removeChildAt(myCanvas.getChildIndex(event.mouseTarget.parent)); depending on whether the mouse is over the root Panel component or the child containers added to the panel. The harder part is identifying which item in my ArrayCollection corresponds to the mouseTarget. What I've ended up doing is capturing the parent/child path (E.g. TestApp0.canvasShell.myCanvas.myContainer592) in my ArrayCollection, then looping until I find a match and removing that item.
