880 Bay Street will be torn down at some point in the future. The interior fixtures etc all need to be removed, plus clean up on the interior has yet to be completed
Employees from this building moved to 900 Bay, 77 Grenville, and 222 Jarvis.
The overall plan is to reduce government office size and centralize operations. Essentially reversing a plan from a couple decades ago, when regional offices were set up. They realized how difficult it was to work with colleagues in North Bay, Peterborough, London etc.
So 880 Bay will be rebuilt at some point. How big, no one knows. Employees will always be around to fill it as there are tons of leases the Gov't would love to lose.
They would never allow a residential/commercial space to be built, as the intention is to have a complete block of government offices for logistical and security reasons. So once this building is levelled, it may sit for quite some time. It's really unfortunate, as many government office spaces are really run down, old, and set up in a way that blocks light, communication etc. So having a bright new space would be fantastic for moral.
222 Jarvis was a great example of this, as it's an incredible modern space (by gov't standards) that has lots of areas to relax and hang out with colleagues.
Of course, any money spent on giving employees adequate work environments would be a waste of taxpayer money
