There are multiple layers to that question.
The decision of how much renewables to have in Ontario was a supply-mix planning exercise undertaken by the then Ontario Power Authority, now the Independent Electricity System Operator. It largely solves for how much energy we need and how much energy we bring in response to that demand. That would be one part of the equation.
The second part of the equation is around the policy decisions that were undertaken in terms of how to bring that—not in terms of quantity, but how to bring it on. A large part of that was through the feed-in tariff programs. There would have been market research undertaken as a parallel to define the levels of pricing needed in order to bring the volume of renewals that were needed.
