You don't honestly think the designers and city approved every West station being copper clad without knowing full well what copper looks like in Calgary? I believe you can chemically treat copper to speed up the oxidization, but without any moist air, its likely going to be deep brown for a while. Enjoy the shiny while it lasts.
Best we'll get is a blueish/green steel color eventually. Here's the Knox church downtown (built 1912)
