Toronto’s swelling bedrock - Spacing Toronto

2014-10-03  In general, Toronto is a relatively easy place to build underground. Our glacial history left the city with stiff clayey soil and our earthquakes are small and infrequent. The soil is forgiving when excavating and has low permeability, meaning excavations can be made dry (a very big deal when working underground).

Abrasion occurs when fine particles and fragments held in the ice, situated at or near the base of a glacier, move across the underlying material, which is commonly called bedrock. The process of abrasion can striate and polish fragments ...

The melting of ice from the past glacial age altered the Toronto region’s landscape profoundly. Approximately 11,000 years ago a body of water much larger (about 130 feet [40 metres] higher) than the present-day Lake Ontario was in existence there—a glacial lake referred to as Lake Iroquois. With the opening up of the St. Lawrence River, the lake waters receded, dropping in excess of 300 ...
