For over 60 years Capitol Buildings has been a developer, owner and manager of a diversified portfolio of commercial, industrial and residential properties. We are particularly proud of a group of historically and architecturally significant loft buildings in Toronto’s Downtown West precinct that have been lovingly restored . We believe that our success rests squarely on the success of our Tenants.  That is why we have invested heavily in equipping our buildings with the modern amenities our tenants require while at the same time preserving the unique architectural character of each building.
