In 1909, the Taylors sold the company to Robert Davies (a brother-in-law married to sister Margaret Anne Taylor). Davies changed the name to the "Don Valley Brick Company Limited". In the 1920s a major expansion resulted in a name change to the "Don Valley Brick Works Limited". Electricity was added and a new sand-lime plant was added that created a less expensive brick used for interior construction. In 1928, the company was sold to Strathgowan Investments and was renamed again to the "Toronto Brick Company". At this time the company had reached peak production of about 25 million bricks per year. During the Great Depression, the area to the south of the Brick Works became a large encampment of indigent men from around Canada. They built shanties and were assisted by Toronto residents. During the winters, the men would sleep inside the Brick Works kilns. The company also operated a brick making facility in Birch Cliff from 1913 to 1963 on what was once a sand and gravel quarry. John Price Limited, a smaller brickmaker in east end Toronto on Greenwood Avenue was acquired then merged into the Toronto Brick Company and ceased operating in 1935.
