Correct that title cannot be transferred to the owner until the Condominium Corporation is registered. The registration itself has nothing to do with level of occupancy, and vice versa. Buildings can be registered by the City before occupancy has even been started, as happened with the Berczy on Front Street. The developer has to meet the standard prerequisite requirements established by the City for all condominium corporation registrations, prepare and submit the associated documentation, which is then reviewed by the City. Once any outstanding issues, either with the prerequisite requirements or the associated documents are resolved, the City will register the new condominium at the Ontario land registry office, and the condominium corporation is now created. At this point, the land titles can be transferred to the owners.
A note with respect to the condominium Board. When the condominium corporation is registered, an initial interim Board is appointed by the developer - the Declarant's Board. The Declarant's Board manages the condominium until the property manager appointed by the Declarant (the developer) can organize the initial owner's meeting to elect the owner's Board (the turnover meeting). During this time, all decisions and contracts regarding suppliers - property manager, cleaners, security, and so on, are made by the Developer nominally through the Declarant's Board, which consists of the developer's employees. The new condominium corporation has a one year window to replace much of what has been entered into on the condominium corporation's behalf by the developer. This is why it is so important for the new owner's Board to retain independent legal representation for a qualified condominium lawyer as quickly as possible - to review all the agreements entered into by the developer on the condominium's behalf, and for the new board to establish which ones they are able, and may wish to replace the supplier without penalty. After the one year window has passed, the condominium corporation becomes locked into the contracts for their respective contract durations.
One other issue which may be worth clarification - with the Time and Space building be set up as one condominium corporation for the entire building, two corporations (north and south towers respectively) or more. While this may not effect the registration timing that much, it will impact how long it takes to organize and hold the turnover meeting. If there is more than one Condominium Corporation in the building, or if there are commercial components which are separately titled, outside of the condominium corporation, the building will usually have some 'shared facilities' which will be managed through a shared facilities reciprocal agreement. Such agreements can be titled to favour the commercial components, especially if they continue to be owned by the original developer. Again, important for the new Board(s) to get legal advice on board as quickly as possible in order to fully understand the roles and obligations of the condominium corporation and other entities in such arrangements, and to protect your interests.
