Pizza oven affected Montreal air quality readings, report says

Montrealers can breathe a sigh of relief to learn their air is less polluted than previously thought — due in part to a pizza oven that was skewing air quality readings. An environmental report released this week shows the number of days with poor air quality plunged last year, right after the city closed a sampling station that was next to a pizzeria with a wood-burning oven. The city registered 29 days of bad quality air in 2016, compared to 64 the year prior.
