A PVC liner is inserted into a watermain between two manholes. Hot steam is then used to expand the liner to the width of pipe. The thermosetting resin in the liner is then cured by the steam and hardens. After cooling, the liner is now waterproof. This trenchless technology is used to stop leaks from imperfections or gaps in piping.

The Elgin building, now part of the Bay Adelaide CentrUpdated or built in 1910 by James Havill for Holt, Renfrew & Co., purveyors of fur at the time, this building originally occupied the northwest corner of Yonge and Adelaide as part of the 1850 Elgin building  (See the image below for what the building looked like before being moved – Vik Pahwa, Jan 2013). The facade was moved north to Temperance Street for the Bay Adelaide Centre. The building was elongated to house mechanical equipment on its upper floors for the adjacent building. The extension, a modern addition cast from the original building facade, is known as a ghost wall.
