1 On October 31, 2024, the MOI announced that it has developed a program to deliver up to $400 million in subsidies to internet service providers (ISPs) for work associated with designated broadband projects. The program is intended to enable ISPs to successfully and safely attach their material and equipment to the Company’s poles to bring connectivity to rural communities as part of a designated broadband project as defined under Building Broadband Faster Act (Ontario). A portion of these subsidies is used to reimburse Hydro One Networks on behalf of ISPs for their share of enablement costs incurred to facilitate the program to date. During 2025, Ministry replaced MOI in making broadband subsidy payments to Hydro One.
