The Canadian province pushed aside Florida with an installation of 46 MW of solar PV and was only behind New Jersey, 57 MW, and California with 212 MW according to a report by the Interstate Renewable Energy Council (IREC).

As a contractor to the US Government, IREC only reports on developments in the US. However, "If Ontario were a U.S. state, it would have ranked third on IREC's list of states," said the report.
