I'm pretty certain there is one at the PCV also. I might downsize those bills to $50 though just to be on the safe side.
Having set that I exchanged £50 notes (roughly the same value equivalent as $100 CAD) at both the PP and the Blau, but I had checked on previous visits to make sure they would accept them.
They do inspect every note, so make sure they are clean, not torn and not written on.
