Charles Ernest Harper (1867 to 1944-02-27) was a son of Major Harper (1835-11-01 to 1917-04-27). C. Ernest Harper was mayor of Whitby in 1918, 1920, and 1921. An online document giving a walking tour of Whitby includes the following.
"205 Perry St. was built in the 1850s by Major Harper, a machinist, who along with Stephen Gross, established a planing mill a block west at Brock St. in 1853. Thus equipped, he and his stepfather did all the woodwork in the new County Court House (#14) and all the Grand Trunk Railway Stations from Toronto to Cobourg which were built in 1856. Later, he operated a machine shop around the corner in what is now Rousseau's Heritage House at 216 Mary St. E. Here, he developed new woodworking machinery and manufactured shells during the 1st World War. Harper was Whitby's Police Magistrate from 1881 until his death in 1917." |
