Osgoode Hall Law School moved to a new building on the York University campus in the late 1960s. The building had a series of minor renovations and upgrades, but for the most part remained untouched for 41 years. This led to a significant deferred maintenance problem and meant that the facility was no longer suitable for the delivery of a modern law school program. Major renovations involved the substantial gutting of the five-storey building, including most mechanical and electrical distribution networks and devices, which allowed the space to be completely redesigned and repurposed. Over 190,000 square feet were upgraded, and a single-storey addition of 23,100 square feet was constructed over the podium structure of the existing library reading room.
