For CO2 emissions the vast majority comes from vehicles and manufacturing, while the majority of the power grid is nuclear and hydro (with gas plants and wind turbines filling out most of the remainder). Unfortunately the current conversion to renewable energy has been axed by the current government, but it's still a start.
As for other countries, IIRC on other threads it has been mentioned that even major polluters on non-western countries like China are starting to clamp down on pollution.
Ontario was able to faze out coal plants because a significant amount of our industry has shut down and relocated elsewhere, and with the scheduled GM plant closure next year it's a trend that's gonna continue. We tightened regulations which drove up costs and industries decided to close shop and move elsewhere.
This is something that's also happening in China, some of their dirtiest and most toxic industries are starting to relocate to other poorer countries in the area as the costs of labour start going up in China.
Actually, if I am reading this page correctly it seems like the amount of energy production has
increased overall:
https://www.ontario.ca/page/end-coal
In 2003 ~25% of the power grid (~7,587MW) was powered by coal. By 2014 all coal plants were shutdown.
However, in the meantime significant other capacity was added to the system:
A new supply mix for ontario
Coal-fired electricity was replaced by a mix of baseload, intermittent and peaking capacity and a strong conservation and demand management approach
Nuclear: +1,500 MW
Two units at Bruce Power were refurbished and returned to service in 2012.
Natural Gas: +5,500 MW
The addition of new combined cycle facilities, a peaking plant and combined heat and power facilities.
Non-Hydro Renewables: +5,500 MW
Added generation under procurements including Renewable Energy Standard Offer Program (RESOP), and Feed-in-Tariff Program (FIT).
So apparently there was ~12,500MW added to the grid during the same timeframe, which after subtracting coal production still leaves a net gain of ~4,913MW.
That's not to say that relocating industries didn't have an impact as well of course.
