This is the best summary I could come up with:

Ontario is proceeding with a massive, multibillion-dollar refurbishment of four aging nuclear reactors at its Pickering power plant east of Toronto, according to two provincial government sources.

The decision will be formally unveiled by Ontario Energy Minister Todd Smith at the facility in Pickering on Tuesday, a senior government source said.

Another government official said the province has approved a $2-billion budget for Ontario Power Generation, the plant’s owner, to complete the necessary engineering and design work and order crucial components, which can require years to manufacture.

Refurbishments under way at OPG’s Darlington nuclear plant in Clarington, and at Bruce Power’s station in Tiverton, have cost between $2-billion and more than $3-billion a reactor.

Mr. Smith received OPG’s report last summer, but his ministry rebuffed a request from this newspaper to release it under the province’s freedom of information legislation.

OPG has applied to the Canadian Nuclear Safety Commission, which regulates the industry, for permission to operate them until late 2026.
