Make my world space Canvas always render on top

How do I make the Image inside my World Space Canvas render on top of objects that would normally obscure it?

I have a waypoint attached to a target that is meant to render in front of meshes that obscure it in 3D space.

UPDATE: To Clarify, a lot of answers to this question previously are obsolete due to changes in the rendering. I have asked again in the hopes of finding a more up-to-date solution.
