Remember the last time there was a smog advisory in the Ottawa Valley?

You'd have to go back to 2014. There were none last year and none so far this year.Things weren't so nice about a decade ago, before Ontario closed all of its coal-fired power generation plants (the last, in Thunder Bay, closed in 2014).

In 2005 there were 25 smog advisory days in the Ottawa area and 53 across Ontario. By 2009 there were just four smog advisories in the valley. And by 2013, there was only one such advisory.

"This is a huge achievement. It's a good news story for the environment," said Paul Parker, a faculty of environment professor at the University of Waterloo, on CBC Radio's Ottawa Morning on Monday.
