MacKinnon was born in 1869 in Whycocomaugh, Nova Scotia and passed away on August 15, 1946. In 1907, Sam Sutherland and J.Q. MacKinnon came to Revelstoke and operated a men's clothing store as McKinnon and Sutherland. In the large illuminated sign on their building, the "a" was left out of MacKinnon by mistake, so it was decided to leave it out in future business dealings.
