During his law practice he was counsel before several administrative tribunals in land use and transportation. His major official plan change success occurred in 1972 when as counsel for Canadian National and Canadian Pacific railways and their subsidiaries he appeared before the Ontario Municipal Board in a six-week contested hearing that resulted in the change of the official plan for all of the railway use lands around Union Station (Toronto) from Yonge Street to Bathurst Street (185 acres) to a high density mix of residential, commercial, entertainment, hotels, sport centres and other uses including construction of the CN Tower. That official plan is the basis for years of enormous development on the lands - lands then and now worth billions of dollars. It was/is the largest official plan change in the history of Canada.
