The Science Centre building was first opened in 1969 and is in need of repairs, according to John Carmichael, chair of the centre's board of trustees. WATCH | Ford says current Science Centre site 'doesn't cut it':Infrastructure Minister Kinga Surma says a business case that showed it would be more cost-effective to build a new Science Centre at Ontario Place, rather than invest in improvements at its current location. The city says the terms of the lease only permit the Science Centre to demolish and build new structures for the purpose of operating as a science centre. Construction on the new centre will begin in 2025 with its opening expected for 2028, the Science Centre said in a statement this week. (Ontario Place is one of the terminal stations of the Ontario Line, a 15.6-kilometre subway line that would run from Ontario Place in the west to the current Science Centre in the east).
