Thanks all for the comments.
This shot is one of a few hundred that I took about ten years ago over the course of a year.
I spent my weekends meeting, chatting with, and with their permission, photographing a number of colonies of homeless persons in a couple of different locations in downtown Toronto.
I learned a great deal about street etiquette, and their lives in general when one no longer has access to proper, food, clothing and shelter, especially in the cold winter months.
I have continued to photograph homeless people when I see images that I feel are compelling and tell stories.
There are many who feel that this kind of photography is invasive and exploitive, because in many cases the subjects have no power to prevent their photos from being taken if they so wish.
I heard it disparaged by one photographer as "The low-hanging fruit on the street photography tree."
I of course disagree with both sentiments and as an aside, feel that the low hanging fruit on the street photography tree is pictures of people pathetically, and addictively engrossed in their various "devices". But that's a discussion for another time and place.
