In November 2018 Ontario's Progressive Conservative government changed the existing 2030 target (37% below our 1990 emissions) to match those of the Federal government (30% below 2005).
They cancelled the cap-and-trade program (Bill 4, Cap and Trade Cancellation Act). This Bill repeals Ontario’s cap-and-trade regime under the Climate Change Mitigation and Low-carbon Act, which had established a successful “polluter pay” carbon pricing system that generated funds for climate change mitigation and adaptation.
As a result of Ontario cancelling the cap-and-trade program the Federal government implemented a carbon pricing scheme (starting in January 1, 2019). The Federal government claims that they are going to rebate about 90% of the moneys collected directly to Ontarians and that the majority will receive more than they will have to pay as a result of the carbon price. Details of how the rebate is to be processed are not available (as of late December 2018.)
