Completed Niagara Tunnel Project to Provide Renewable Power for 100 Years

New Ontario Government Committed to Building Clean, Reliable Energy System

Ministry of Energy

The new Ontario government is now harnessing more clean, renewable electricity from Niagara Falls through the completed Niagara Tunnel Project. 

The new tunnel, which is more than 10 kilometers in length, is channelling additional water from the Niagara River to flow to the Sir Adam Beck Generating Station at a rate of 500 cubic metres per second. This will supply Ontario with enough electricity to power the homes and businesses of a city the size of Barrie.

The largest hydroelectric project to come into service in Ontario for the past 50 years, the Niagara Tunnel Project is a significant provincial achievement, employing 580 people during the peak of construction.

Building a clean, reliable energy system is part of the new Ontario government's plan to ensure we have the electricity we need to power the province's homes, schools, hospitals and economy.

Quick Facts

  • When under construction, the Niagara Tunnel Project was the largest renewable energy project of its type anywhere in the world.
  • The Niagara Tunnel is as high as a four-storey building, and will propel water at a rate of 500 cubic metres per second, fast enough to fill an Olympic-sized swimming pool in a matter of seconds.
  • About 500,000 cubic metres of concrete was used to line the tunnel – enough to build a sidewalk from Windsor to Quebec City.
  • The tunnel liner wall is 60 centimetres thick and made of cast-in-place concrete.
  • Since 2003, more than 360 megawatts of new, upgraded and refurbished waterpower projects have come online in Ontario, enough to power an estimated 240,000 households.
