CSI Annex

720 Bathurst Street, Uncategorized,

CSI Annex (720 Bathurst) is a five-story, beautifully restored brick & beam building packed with innovators. Each of the coworking floors has its own unique vibe.

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 business with fewer than three employees. It’s cheaper than an office and gives you way more perks.” – Itay

The Building & Accessibility

We bought and renovated CSI Annex in 2010 with $2M coming from the sale of Community Bonds. The building, built before 1920, boasts five floors totaling 36,000 square feet of social innovation potential bursting with entrepreneurial energy. 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.

Ground Floor
The ground floor of CSI Annex is fully accessible for mobile devices. Guests will enter through the south-east door – the entrance is equipped with a lift.

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.

Learn more about our buildings’ accessibility.

We are committed to ensuring all members and their guests are able to use our services. If you have any accessibility concerns or questions please reach out the Community Manager: Gonzalo(at)socialinnovation.ca.

Event Space

If high ceilings, exposed brick, wood beams and vintage furniture seem like a good backdrop for your event, then you’re in the right place!
