I'm a bit lukewarm on this list. Ideally a list like this would be comprised of at least 15 burgers from actual burger joints, rather than the mere five featured here -- but I understand that as much as Toronto's burger scene has moved forward in the last few years, it still needs work. And it's sad that of those five, two are what I would consider nostalgia places, that trade more on fond memories than actual taste (Apache and Golden Star).
Then there are burgers that aren't actually burgers (Lamb? Elk??), and a disconcerting number of fancy-pants burgers. All in all it's an interesting list, but one I can't say I'm crazy about.
