Dufresne Arcade Photo Studio, Toronto: Unknown Man

This photo was found in an old photo album with a floral & white cover. Part of my family photo collection from the area around Cornwall, Stormont, Ontario, Canada. These are mostly descendants of United Empire Loyalists. Some of the family members may have travelled or been living in Quebec (Montreal area), Western Canada, the U.S., etc. at the time that these photos were taken.

Who is the man in this photo?
