What was discovered at Place-des-Arts?

I blinked when I read this fresh CBC headline: … crack discovered at Place-des-Arts station. Did a cleaner find a shipment of drugs hidden under a bench, or people hiding out in one of the station’s mezzanine corners, smoking it?

Nope. “Service on the Metro’s Green line has been restored, for the most part, after a crack was discovered in a structure at Place-des-Arts station.”

Oh. Well, not good. But different.
