Of course, economics determines in large part what gets published. But though this may not be entirely desirable, there's a compelling argument for the marketplace determining quality. Shakespeare, for instance, went with whatever he could find that would appeal to audiences. This, I'd say, is the best advice any young Canadian writer can take, rather than listening to some gadfly spouting imagination-limiting prescriptivism.
