To make a JavaFx canvas resizable all that needs to be done is override the min/pref/max methods. Make it resizable and implement the resize method.

With this method no width/height listeners are necessary to trigger a redraw. It is also no longer necessary to bind the size of the width and height to the container.

public class ResizableCanvas extends Canvas {

    @Override
    public double minHeight(double width)
    {
        return 64;
    }

    @Override
    public double maxHeight(double width)
    {
        return 1000;
    }

    @Override
    public double prefHeight(double width)
    {
        return minHeight(width);
    }

    @Override
    public double minWidth(double height)
    {
        return 0;
    }

    @Override
    public double maxWidth(double height)
    {
        return 10000;
    }

    @Override
    public boolean isResizable()
    {
        return true;
    }

    @Override
    public void resize(double width, double height)
    {
        super.setWidth(width);
        super.setHeight(height);
        paint();
    }

Note that the resize method cannot simply call Node.resize(width,height), because the standard implementation is effectivele empty.
