No. If Toronto Hydro decides to proceed with developing a plan to install windmills in Lake Ontario, the potential plan would be subject to a full Environmental Assessment process that includes significant public consultation and input.
But before any such plan can be developed, Toronto Hydro would have to know that there is enough wind available to make the project economically viable.
As well, once the potential plan is made public, it is subject to an environmental assessment, which it may or may not pass.
So, if windmills are ever built in the lake, it will only be after an extensive environmental assessment and public review.
