I just checked the Environment Canada website and at noon today the temperature was 10C. This means that Ottawa drivers risk running afoul of the by-law enforcement officers if they’re observed idling their cars for more than three minutes if the temperature is 5C or warmer, taking into consideration the windchill. I don’t recall hearing about anyone being charged since they started enforcing it a couple of years ago, so perhaps Ottawa drivers are turning off their engines when they’re waiting to pick someone up.

What do you think of this by-law?
