You can try this place,
http://www.kenmcgeeautobooks.com/ it's in Goderich, I worked right near it when I lived there from 2000-2004, Ontario and they have all sorts of auto books, I think they have an e-bay store as well. On a sidenote their website is only viewable with Internet Explorer, it won't work with Firefox for some reason. They carry old shop manuals, advertisements, etc.
