CSI Annex: 36,000 sq. ft. of social innovation potential

CSI Annex (720 Bathurst St.) is a five-story, beautifully-restored brick-and-beam building bursting with entrepreneurial energy. We bought and renovated this building, whose beginnings date back to the 1920s, in 2010 with $2M coming from the sale of Community Bonds.

Each of the coworking floors has its own unique vibe. The first floor is a community gathering place with event spaces and plenty of social space to chill-out and connect. The second and third floors have a vibrant mix of private offices, private desks and shared desks, hosting an incredible diversity of members in a beautiful and open collaborative environment. Floors four and five have larger private offices and themed incubation spaces focussed on improving our city and bringing new projects to life. 

“An amazing atmosphere. Everyone is extremely friendly but at the same time working hard so it keeps you motivated. Its a no-brainer option for any small business: it’s cheaper than an office and gives you way more perks.”

– Itay, CSI Annex Member

Upper Floors
The 2nd, 3rd, 4th, 5th floors of CSI Annex are not fully accessible: they can be reached via an elevator with a door of 30” width. Functionally this means that while we are able to accommodate many accessibility devices, those using larger devices may need alternative arrangements.

Should guests wish to access the elevator and the upper floors they will enter through the north side entrance.
