THE CLIMATE OF TORONTO.
R. F. STUPART, F.R.S.C.,
Director Dominion Meteorological Service.
TORONTO is situated on the north shore of Lake Ontario on a peninsula formed by the Great Lakes (Huron, including the Georgian Bay, Erie and Ontario). The land in this peninsula reaches an approximate height of 700 feet above the lake in a ridge which parallels the Ontario shore line at a distance of about twenty miles and then trends away to the northwestward, increasing to a height of 1500 feet just south of the Georgian Bay. These geographical features play an important role among factors affecting the climate of Toronto.
An Observatory was established at Toronto in 1840, and meteorological observations have been taken continuously ever since. Up to 1907 there was practically no change in the location of the instruments, although as time went on the city grew up around the University property, within the boundaries of which the Observatory was placed. It was not, however, until 1906, that any building was erected near enough to impair the Observatory
