Mining Update – End of 2017


2017 saw the start of many different major construction activities at Crosstown station sites across Eglinton: concrete pours, steel installation, piling, and excavation to name a few. In addition, one major activity unique in Toronto’s urban landscape began at some sites – mining.

Since the start of mining at Laird Station in August, progress has been steady. What started as a few steel supports drilled into the excavated wall has advanced, right in the heart of the city.

“Mining in a dense urban area comes with its fair share of challenges, such as operational logistics in tight spaces and noise mitigation,” said Rachel Pattimore, Communications Specialist for the Crosstown’s Mined Stations. “By bringing in world-class engineers and other specialists, we can address issues proactively to stay on schedule.”

In addition to the secondary entrance, activity has also begun at the primary entrance for the future Laird Station.

At Avenue station, mining recently began for the secondary station entrance. At the primary entrance, operations will begin in the new-year. Oakwood Station is also preparing to start at the primary entrance (on the north side of Eglinton at Oakwood) to begin early next year.

To facilitate mining, cranes are installed at each designated site to help transport equipment, materials down below, and the excavated earth back up. At Oakwood and Avenue, specialty overhead cranes have been installed that are controlled by remote control, and that excel at working in confined spaces. When the Oakwood overhead crane was installed, it was the first of its type in Canada. At Laird, lower density has allowed for the use of traditional tower cranes.
