I entered the business like most of us from high school in 1961 with James Richardson & Sons and traded under Neil Potter from 1965. Next stop was Burns to 1971 and then spent 35 years with 3 Macs (MacDougall, MacDougall & MacTier Inc.), retiring November 2005. Colin O'Handley and Dave Dotzko were with me most of that time and are still there today.
Memories include the summer of 1974 when some daily TSE total volumes were well under 1 million shares! And of the course 2 floor closures. Perhaps showing my age, the floors were certainly more fun , but grant the move to trading with computers was more productive and profitable.
