Our 2025–2029 investment plan

Learn more about our five-year investment plan and rate application.

As the local electricity distributor for the city of Toronto, Toronto Hydro delivers electricity to households and businesses across the city on a daily basis. But the way we do it is evolving.

To ensure we can continue powering Canada’s largest city safely and reliably for years to come, we’re developing our next five-year investment plan: for 2025 to 2029. In addition to being responsive to legal and regulatory requirements, input from business experts and customer feedback, we're developing our plan to address the following challenges ahead of us:

  • Renewing and upgrading deteriorating infrastructure
  • Serving the economic needs of a growing city
  • Adapting to changes in the way customers use electricity
  • Building resilience in the face of extreme weather and cyber security attacks

Please note that our 2025–2029 Investment Plan Customer Engagement Survey is now closed. Thank you to all of our customers who completed the survey for your feedback. We'll now re-examine and make appropriate changes to our draft plan based on the feedback we received, before filing our plan with the Ontario Energy Board later this year.

Our strategic priorities

Our draft investment plan for 2025–2029 is focused on three main priorities:

  1. Keeping our grid in good condition

    We’ve invested consistently in the upkeep of our aging infrastructure and improving the performance of our system over the last decade. Moving forward, Toronto Hydro is focused on renewing aging, deteriorating and obsolete equipment, to help minimize the risk of outages, ensure safe operations, and mitigate environmental hazards posed by old equipment.

  2. Preparing the grid for growth

    As the city continues to grow and more customers turn to electricity to power their homes, vehicles and businesses, Toronto Hydro has a critical role to play in expanding and enhancing the local grid so that customers can continue to plug in safely and reliably.

  3. Modernizing our grid and operations

    As more customers plug into electrified technologies — including those capable of sending electricity back to the grid — we need to invest in building a more intelligent and resilient grid. This includes integrating new smart grid technologies that can help us restore power to customers faster and at a lower cost than today, as well as investments to strengthen the grid against extreme weather and cyber attacks.

About the rate application process

Electricity distributors in Ontario, like Toronto Hydro, are entirely funded by the distribution rates paid by their customers. To have our rates approved, Toronto Hydro is required to submit a plan for our proposed prices (rates) and spending to the Ontario Energy Board (OEB), Ontario's independent energy regulator. The OEB will then review our plan and proposed rates for 2025–2029 in an open and transparent public process known as a rate application.

Customer input is an essential part of the rate application process. Toronto Hydro is accountable to the OEB for considering customer needs and preferences as we develop our plan, and for explaining and demonstrating how customer feedback informed the plan.

  1. Identify customer needs, preferences and priorities. [✔]

    In 2022, we asked many types of customers from across the city about their needs and priorities for electricity distribution service.

  2. Use customer feedback to guide development of our draft plan. [✔]

    Our planners were given summaries of the key findings from our initial customer engagement to consider as they began building their plans.

  3. Collect customer feedback on our draft plan. [✔]

    We then went back to customers — via an online customer survey — to get feedback on our draft plan and to ask customers how the plan could better meet their needs and preferences.

  4. Use customer feedback to finalize the plan. [⇦ We are here]

    We'll now re-examine and make appropriate changes to our draft plan based on the feedback we received from customers during step 3.

  5. Submit the plan to the Ontario Energy Board (OEB).

    Finally, we'll file our plan with the OEB along with a report summarizing the results of our customer engagement. The OEB, consumer advocates and other interested groups will examine the plan as part of the rate application process.
