Why does Saul head back to Northern Ontario? Where does he stay when he first arrives and what does he do for work? Explain.

Okay, I'm pretty sure that you are referring to chapter 45. Saul Says he's unsure why he returned to Northern Ontario in 1978. He just wound up near Redditt where his brother Benjamin had once found them. I think the memory of his family being reunited might have had something to do with this. Saul managed to get on with a crew breaking rock at a quarry.
