I can't find a schedule for this on CBC Radio's AIH website, but I found this link in a search. Typically, it was aired on As It Happens on the last weekday before Christmas Eve, I think.
It was first read on-air in 1979 and has been repeated annually. It was written as a ghost story, of a kind, for his wife.
