Like any energy program the Ontario liberals have introduced expect the following;

1) another giveaway to public sector unions
2) costs far over and above projections 
3) an accelerated loss of private sector manufacturing jobs
4) carbon emissions will actually go up considering the incoming US government will not sign the Paris accord and the benefits going to Quebec which is producing green energy profitably at a far lower cost, yet the government will claim the moral high ground
5) more taxpayer  money will flow from Ontario to Quebec 
6) hydro bills going further up, the 8% rebate is window dressing
7) a sudden apology from the premier just before the next election
