Toronto Public Library's Historicity http://historicity.tpl.toronto.on.ca/
has a fairly good map of the Toronto wards around that time.
Enter, and search for ward and map
In the search results, you want Maps, and it's 1. Plan of City of Toronto and Suburbs.
The map shows the numbered wards (red lines, red letters) and the old wards in coloured background. It looks like east of Dufferin south of King is St. George, north of King is St. Andrew, and west of Dufferin is St. Albans Ward, which may have been enumerated in 1891 as St. Marks' or Parkdale.
