Ontario's first small nuclear reactor will be late and cost more than planned

Ontario's first small nuclear reactor will be late. It will also cost more than planned. A nuclear reactor makes electricity. This new kind is called a small modular reactor. It is smaller than most older nuclear reactors. Ontario Power Generation is building it at its Darlington site, east of Toronto. This power company is owned by the government of Ontario. It planned to start using the reactor in October 2030, at a cost of $7.7 billion. The company has not said how late it will be or how much more it will cost. It expects to know more by mid-2027.
