2D Screen Point Transform and CanvasScaler

I'm getting the screen position of something to show an object on top. However, because I'm using a Canvas Scaler, this doesn't always work because it doesn't take into account the canvas scaler. With it disabled, this works properly. How can I properly use the canvas scaler with this?

Code (CSharp):

1. Vector2 ActualPosition;
2. RectTransform CanvasTransform = TheCanvas.transform as RectTransform;
3.  
4. RectTransformUtility.ScreenPointToLocalPointInRectangle(CanvasTransform, Position + new Vector2(0, CardOverlaySize.y / 2 + 10), TheCanvas.worldCamera, out ActualPosition);
5.  
6. Vector3 TransformedPosition = TheCanvas.transform.TransformPoint(ActualPosition);
7.  
8. CardOverlayTransform.transform.position = TransformedPosition;
9.  
10.  

 

Anyone?
