Can you explain why The Apprenticeship of Duddy Kravitz is in the third person point of view?

From the text:

Some sixty miles from Montreal, set high in the Laurentian hills on the shore of a splendid blue lake, Ste. Agathe des Monts had been made the middle-class Jewish community's own resort town many years ago.

The third-person narrator is setting the stage and telling the story.
