Data source(s) and notes about the submission:

Regarding reductions on Scope 2 emissions from Purchased Electricity

Due to the retirement of coal-fired generation and the reduced demand for electricity, the GHG emissions from Ontario's electricity sector fell by 80% since 2005.
https://www.ieso.ca/en/Learn/Ontario-Supply-Mix/Ontario-Energy-Capacity

In 2019, energy production relied heavily on nuclear (61%) and hydro (25%), both of which are considered low carbon. Only 6% of our electricity mix was fossil fuel base (oil/gas).
