YXS-YVR was the last flight I took on one. When I was in YYC a few years ago, there was about 6 of them parked on the ground, check out google maps:

Other interesting notes:
The first jet to be certified for LCY airport, and its 7.5degree approach, it has quite excellent short field performance.
The Queen's flight operates them for European trips; and Charles was certified to fly them (he overran an airport in scotland once in one)
they were also operated by Air Wisconsin as a United Express operator, only other largish operator I know of in North America
Basically a little too short ranged for North America, but they live on in Europe.
