Maybe I'm just showing my age, but I'm wondering if there are any places in Canada that have and actually use noise legislation against loud bikes and cars. Around here (Saint John, NB) the issue isn't kids putting fart-can mufflers on their Civics. That happens, but not in large numbers. The issue is the hordes of men suffering from a mid-life crisis who go out and buy a Harley and then bore out the exhaust or just cut it off and install straight pipes. My wife and I live about a kilometre from a four-lane highway that we can't see and usually can't hear. Cars can't be heard, the occasional heavy truck might be heard, but you can hear the jack-asses on their Harley's coming and going for miles. The best I can figure around here is that the police see this as a by-law issue and they don't like enforcing bylaws.
I'm interested to see if any parts of Canada actually crack down on this. I recall that BC was planning to bring in provincial legislation which would cap sound levels at 85 decibels (still pretty loud) but I don't know if they ever did that. Anyone from BC know if this happened?
