I can't find James Sr either..
But, I did find son David's obituary. Toronto Star June 29, 2006 Page C14
David John Mackay, died June 27, 2006. Formerly of Caledon. Survived by wife A, son S (wife C), and daughter W (husband B Sibley). 2 grandsons. Survived by brothers Alexander and Dr. James (wife A) Mackay. He worked at Bell Canada for 37 years. Funeral is in London, Ontario. It doesn't say specifically that he died there, but I would think so. If people wish to donate in David's memory, a London charity is mentioned.
