Not sure about Gagetown.
But to elaborate on St Jean...the Qs at the CMR weren`t being used when I was there. All my friends ended up in St Hubert, which is about a half hour away. They carpooled, but found it a large, costly pain in the butt. I`m not sure on the cost of the Q`s, but most half decent appt`s in St Jean are around the 450-600 range. You can certainly get them for less, but just be careful cause there`s alot of crappy areas. I was attach posted to St Jean for a while and lived with my girlfriend near downtown in a really nice loft. We paid 600, which was on the higher end, but it was worth it.
Good Luck
