Does anyone have experience phoning 416-808-6600 (Parking Enforcement) to report vehicles parked in bike lanes?

Picked up a copy of the Toronto cycling map and noticed [this](http://i.imgur.com/7dbs0Ve.jpg) on the back. I'd love to be proactive about getting people ticketed for parking in bike lanes, but am wondering if it's worth my while to take the time to contact parking enforcement... Does anyone have any experience trying this? And if you did call, did anything happen as a result?
