Project Description
The North Shore Link Transmission Line is a 106 km double-circuit 230 kV transmission project extending from Sault Ste. Marie to Wharncliffe, Ontario. The corridor includes approximately 85 privately owned parcels, 45 km of Crown Land, and roughly 25 km of inaccessible terrain, creating complex requirements for access, land ownership, field investigations, and corridor-wide data management.
TULLOCH is supporting the project through coordinated surveying, geospatial, land ownership, and geotechnical assignments. The work combines extensive field programs with digital tools that help the project team manage property information, consultation records, technical data, and design requirements across a long and challenging transmission corridor.
