Last year, on the coldest day of winter, a few of us went out on a tour of homelessness in Toronto - organized by the Shout! Clinic over on Jarvis and Carlton. The greenhouse at Allan Gardens is, apparently, one of the very few places in Toronto that the homeless are allowed to "loiter" in during the day - most shelters are closed from morning to evenng, and loitering on private property (such as malls) is not possible due to security.
The thing of it is that, as the tour lasted pretty much the whole day, we really did get to experience first-hand what the homeless have to go though, especially on very cold days - I can tell you that we very happy to have the greenhouse to loiter is as we warmed up.
I also have to say that I really do appreciate the role that the various Coffee Times, and other "downmarket" coffee shops fill in the city - many of these places allow their customers, who are often homeless, to loiter as well, often for hours on end.
It will be interesting to see what becomes of this area vis-a-vis the above.
