Welcome to Ottawa’s premier AAA office complex, in the heart of the city.

Home to

Constitution Square was born out of the vision to create a holistic workplace. From the first tower breaking ground decades ago to today’s fast-evolving work reality, we stay true to that vision.   

Now, more than ever, CSQ is your place to be, work, connect and collaborate.
