While typically found in insulators, ferroelectric-like distortions can remain robust against increasing itineracy, giving rise to so-called \"polar metals\". Here, we investigate the temperature-dependent electronic structure of Ca$_3$Ru$_2$O$_7$, a correlated oxide metal in which octahedral tilts and rotations combine to mediate pronounced polar distortions.
