The riding was formed in 1926 from parts of the old Toronto Northeast and Toronto Southeast ridings. Its western boundary starting at
Toronto Harbour went north following the line of Simcoe Street. At
Queen Street West it jogged east a block to University Avenue. It followed this street north continuing along Queen's Park Crescent East and Avenue Road north to St. Clair Avenue West. At St. Clair it turned east and went to Yonge Street. At Yonge it turned south and followed this street to Bloor Street. It then turned east following Bloor until it reached
Sherbourne Street. It then followed Sherbourne back south until it met the harbour. Prior to the 1934 election, the riding boundaries were changed. The western boundary was moved east to Bay Street. The boundary followed Bay Street north from the harbour until it curved northwest to meet Davenport Road. It followed Davenport until it met Avenue Road. It turned north following Avenue Road north skirting
Upper Canada College on the east side until it met the old
Belt Line Railway right-of-way. It then headed southeast following the right-of-way until it reached Yonge Street. From here it turned south following a line through the Mount Pleasant cemetery and through a ravine called the Vale of Avoca (these days it is called David Balfour Park). It followed the ravine until it reached the
CPR right-of-way. It headed east along this right-of-way until it reached MacLennan Avenue. It then turned south following this street and continued south on the same line when it turned into Sherbourne Street at Bloor. It continued along Sherbourne Street until it reached the harbour. ==Members of Provincial Parliament==
