but I saw a PBV Catalina ( I assume it was a PBV and not a PBY since it was in Canada, which would, I think, make it an OA-10)

Man, it was pretty. I saw it on the ground in the Kincardine airport, and in the air over Owen Sound. There was also a DeHavilland Beaver flying around. A tight DHC-2 Beaver is a half million bucks, I have no idea what the PBV costs or costs to operate- an 18 ton (empty!) aircraft with two 14 cylinder pratt-whitney radials?

Someone still has some money.
