A google search for orphanage +ossington +toronto turned up the following: http://members.rogers.com/nucleara/vocareSep02.htm
"Sister M.Agnes outlined the history of the Carmelites whose origins go back to the desert fathers in the Holy Land. They boast many famous saints throughout their history. At the invitation of Bishop Neil McNeil, in 1913 they established an orphanage in Toronto. They rescued and cared for children and the elderly. A day care center still operates at their site on Ossington Avenue."
The centre is:
Carmelite Day Nursery
108 Harrison St., Toronto
