Well.... Trying to find a Robin aircraft in Canada seems to be a difficult task. Going on Airliners.net and searching for "Robin" and "Canada" results in nothing. The main global search engine is no help either. So, a Canadian repaint of the standard IPACS colours is a good place to start, and a C-GRBN registration borrowed from a 1964 Piper Pa-24 makes sense to me at least!
