Proposed Project: Terminal 1 East Side Renovation (T1 East)

This project involves the following:

As part of the Greater Toronto Airports Authority's (GTAA's) Toronto Pearson Airport Long-Term Investment in Facilities & Terminals (LIFT) Program, the T1 East project is proposed to provide targeted improvements to the east side of Terminal 1, including exterior baggage roadway and apron/roadway works together with renovation and modification of existing interior terminal areas.

The proposed T1 East development is located on the east side of Terminal 1 within existing developed and operational terminal, roadway and apron areas. The exterior project area is approximately 960 m² and is predominantly within previously disturbed, paved airport lands. The project is intended to improve baggage handling and servicing capacity, operational access and connectivity to the existing Terminal 1 Level 1 facilities.

The project scope includes:

• Approximately 960 m² of exterior works on the east side of Terminal 1, including extension and modification of the existing baggage roadway, apron roadway and associated paved operational/service areas.
• A lightweight structural steel enclosure and associated foundations adjacent to the existing Terminal 1 building.
• New and modified access connections to the existing Terminal, including associated structural and architectural modifications.
• Predominantly renovation and modification works within the existing Terminal interior.

Construction activities are expected to include selective demolition and removals; excavation and earthworks; utility investigation, relocation and protection; installation of deep foundations and structural supports; concrete and structural steel works; roadway and apron modifications; paving and line marking; drainage and underground services; installation and modification of baggage handling equipment; mechanical, electrical and controls work; construction of the lightweight enclosure; and associated temporary works, access, protection and reinstatement. Work will be staged to maintain airport operations and access to existing Terminal 1 facilities.

Sustainability best practices will be integrated into both the design and construction phases, aligning with the broader Long-Term Investment in Facilities and Terminals (LIFT) Program at Toronto Pearson Airport.
