In 2014, the Canadian Science and Technology Museum was closed after mould was discovered in the walls, and officials determined the building’s leaky, asbestos-infested roof was at risk of collapse. After extensive repairs and renovations, the museum is set to re-open on Nov. 17. Photographer Blair Gable was given behind-the-scenes access to the museum as workers prepare for the big unveiling.
