T3 Bayside is a groundbreaking timber office structure in Toronto’s Bayside community, positioned along the Lake Ontario shoreline. Standing at 42 meters, it is the tallest timber office building in North America. Hines aims to set a benchmark for sustainable timber construction, creating a top-tier office environment that embodies the ‘live-work-play’ philosophy of the evolving Bayside area.

Enhancing the Public Realm. T3 Bayside is strategically designed to enrich the neighborhood, transforming the former industrial waterfront into a lively urban hub. Centered around a public plaza, the building serves as a pedestrian-friendly entrance to the Bayside development, inviting visitors and linking to the adjacent park and waterfront promenade. Street-level retail and café spaces will foster a bustling atmosphere, making the plaza a vibrant social area for all.


One of the building’s standout features is a series of stepped interior areas that create a continuous flow around the building’s perimeter. The initial three ‘steps’ are accessible to the public, extending the plaza and forming a communal space that eases the transition from public to private areas. These adaptable double-height spaces will host various pop-up events, such as exhibitions and performances. The external articulation of the steps is highlighted through the design of fins and façade details, visually linking the plaza to the interior and inviting exploration.

Flexible and Healthy Workspaces. The upper ‘steps’ lead to office areas, featuring double-height spaces that connect two floors. The design emphasizes tenant flexibility, allowing customization of spaces through removable ‘soft spots’ in the slabs. The open floorplates accommodate various tenants, from small startups to larger corporations, adapting to evolving business needs.

Targeting WELL Certification, the design prioritizes occupant wellness, providing high-quality office space that aligns with contemporary work methods and attracts top tenants. The timber structure is fully exposed, offering a warm aesthetic and fostering a healthy indoor environment. Outstanding amenities, including a tenant lounge and a rooftop terrace with views of Lake Ontario, create diverse break areas, enhancing the workday experience.
