The Toronto District School Board is set to announce a major green initiative Thursday morning.

The TDSB, in conjunction with AMP Solar LP, will announce a no-cost, long-term strategy to install solar panels on up to 450 school rooftops over the next 20 years.

Part of the Go Green: Climate Change Action Plan, the initiative is the largest and most comprehensive program of its kind.

The announcement will be made Thursday morning at 11 a.m. at Hillcrest Public School at 44 Hilton Ave.
