I have heard that Canso CF-OFJ has been on Greenland for a period of 4 weeks, in the autumn 1963, instead of Canso CF-CRP there was home for reparation after a landing accident in Maniitsoq. They flew regular passenger flight between Sonderstrom (Bluie West

and Narssarssuaq (Bluie West 1) and the cities on the west coast, for Greenland Air, on charter from Eastern Provincial Airways.
May be some one has taken photos and that they hopefully will show up in the near future.
Cheers,
Erik
