As Ontario's largest electricity transmission and distribution provider, we are building a better and brighter future for all. We have a responsibility to deliver safe and efficient electricity to our customers, across the province and we are also committed to serving the communities where we live and work.
Built by customers, for customers.
The Investment Plan was directly informed by the feedback of almost 50,000 customers with an evaluation of our current and future system needs.
“Our plan will make smart investments to significantly reduce the impacts of power outages for our customers. With much of our system built in the 1950s and 1960s, it is time to invest in renewing or replacing critical infrastructure in almost every community across the province. Every dollar we invest comes at a cost to our customers, which is why this plan was directly informed by the feedback of almost 50,000 Ontarians. The majority of customers told us they support proactive investments in a resilient and reliable system prepared for climate change.”
