If you are heading to Niagara Falls it is worth an overnight stop in Niagara On The Lake.
As for cell phone use the police have started using unmarked Dodge Caravans, they even had the 'stick family' on the back. The latest story doing the rounds is cops on the street cars watch what the car drivers are doing. Once your are out of the city and the roads are clearer you can open it up a bit, unfortunately if you are driving fast around the city someone will feel the need to go one better, I know of two lads who have been caught at over 150 kph, its classed as racing by the cops and very expensive.
