Were RAAC panels really behind the Ontario Science Centre’s demise?

Were RAAC panels really behind the Ontario Science Centre’s demise?

TORONTO — On June 21 the Ontario Science Centre (OSC) closed its doors the public, just before children and patrons entered its doors for the summer.

During a technical briefing, it was stated a professional engineers’ report found “serious structural deficiencies” with the roof of the building, particularly a type of panel made from Reinforced Autoclaved Aerated Concrete (RAAC), a lightweight form of concrete that was a popular building material from the 1950s to the 1970s.

Since news of the closure, The Daily Commercial News (DCN) has been gathering updates and covering various aspects of the province’s stance and the report’s findings.

From harsh criticisms of the specific type of RAAC panels used, with some comparing them to “waxed cardboard,” to others stating the material isn’t the problem, the provincial government is, the DCN has been listening.

We’ve compiled a list of our recent stories to provide you with an overarching view of the various standpoints, a brief history lesson of the OSC and what the future may or may not hold.
