The official policy is currently to phase out by 2014. There is an election in Ontario on Oct 10, 2007. Current administration did break a promise to phase out coal by 2007 The incumbant Liberal Dalton McGuinty and Conservative leader John Tory are in tie in the polls.
John Tory's plan is to build more nuclear and other clean sources and clean up the coal
This coal energy phase out will reduce air pollution and save at least 657 lives per year.
Some articles on the coal phase out and the pollution reduction benefits of removing coal energy supplying 20% of the electricity.

Ontario's coal plants are responsible for:
36% of Ontario’s airborne mercury emissions;
28% of Ontario’s industrial smog-causing nitrogen oxides emissions;
23% of Ontario’s industrial smog-causing sulphur dioxide emissions; and
8% of Ontario’s industrial PM2.5 small particulate emissions that go deep into our lungs and cause asthma attacks, heart and lung diseases, strokes and premature mortality.
Coal Phase-Out will raise electricity bills by 34 to 53 cents per month
An Ontario coal phase-out would also save at least 657 lives per year in the province, according to an April 2005 report prepared for the Ontario Ministry of Energy.
Ontario has a population of 12.8 million people. The United States has 24 times the population and uses coal for 50% of its power. Assuming proportional coal air pollution effects then the US would have 60 times the number of deaths or over 39,000.
In 2006, Ontario has 6.4 Gigawatts of coal power and a total capacity of 31 Gigawatts. Some of the hydroelectric and other non-coal power sources will not be available during peak summer days.
The total coal free power on summer peak demand days is 22.14 Gigawatts. Various improvements that will be made have a projected 27.2 Gigawatts of peak summer power generation in 2009. From 2010 to 2012, they will add a bit more to 28.3 Gigwatts.
This will cover the expected peak demand of about 27 Gigawatts but not the 17% reserve margin.
So another 4 gigawatts of non-coal peak power is needed in 2010-2012.
There are various options.
The cheapest is to convert coal plants in Thunder Bay and Nanticoke to natural gas (70 million to 156 million per GW).
Add new natural gas for $600 -900 million per GW.
Restart the Pickering A unit 4 nuclear plant for $2.4 billion per GW.
Other alternatives are more aggressive conservation and demand management, more aggressive renewables targets, acquire more cogeneration resources and another natural gas option in Mississauga.
