Surma said moving the Science Centre would save taxpayers $257 million
“The business case confirms that the relocation will save Ontario taxpayers $257 million over a 50-year period when compared to the cost of remaining at the current site and will also provide a greater share of space for programming than is the case at the current site.”

The Auditor General found the relocation's estimated cost had risen $397 million (47%) to $1.444 billion by November 2023, but said the cost of staying would also have risen, without giving a figure.
The March 2023 business case put the cost of staying at Don Mills at $1.304 billion and the cost of moving to Ontario Place at $1.047 billion (both 50-year net present value), a gap of $257 million. On December 3, 2024 the Auditor General reported that 'As of November 2023, based on the latest available cost information, the total cost estimate for building and maintaining the new OSC at Ontario Place increased by $397 million (or 47%)... If these costs are added to the $1.047 billion above, the total is now $1.444 billion.' The Auditor added that 'costs of rehabilitating and remediating the existing OSC site would also have increased', without giving a figure. In February 2026 the province signed a fixed-price $1.04 billion contract to design, build, finance and maintain the new building, which is a different basis from the 50-year estimate.
