Today, it’s been thoughtfully modernized and houses a combination of our growth-ready startups and established companies.

Both MaRS Commons and District 20 are located here and specifically designed to accommodate the growth needs of our startup clients, who are looking for offices where they can build their own company culture while still accessing the benefits of a communal startup community. Facilities like meeting rooms, kitchen space and technology are provided in some instances.


South Tower

The South Tower’s eight storeys offer 200,000 square feet of space and they have been divided into labs and offices for rent.

Located on the second and third floors, the MaRS Incubator provides furnished offices, labs, meeting rooms and kitchen space to emerging science and technology startups. Facilities include shared access to fridges, freezers, Milli-Q water purification, an ice machine, centrifuge, autoclave, and environmental rooms.
