During his life Bertram was employed by the historic Dundas apparel business S. Lennard & Sons Ltd., founded by his grandfather in 1879. Throughout his architectural career Harry Lennard has played important roles in the construction of major landmarks, including the theatre complex then known as Hamilton Place now named First Ontario Concert and the restoration of St. James Anglican Church in Dundas. In 1989 the property was sold to Marjorie Hawkins Clark (1928-2007) and Hugh Clark (1932-2018).
