ok, Surfbum84....
I can relate one of my personal experince that happended many years ago exactly that i lightly tapped the the rear end at the lights, turning right.
1) Did you exchange license plates?
2) Any Whitnesses?
If you wanted to repair the car without going thru insurance, you can, but it depends on the person you are dealing with, so there has to be a mutual agreement. HOWEVER, no insurance companies will recommend that, because the victim can retailiate after the repair, ESPECIALLY personally injuries.
Remember, in Ontario, we have a no-fault insurance, so who ever got the damages, goes back to their own insurance for claims. WHat can get messy is when the victim claims for personal injuries, then you are in hot water and only your insurance company can save your ass.
Then you are in a lawsuit, your insurance company will have their legal department to take care of things, win or lose, it can take 5 to 7 years to go on trial, and most of these minor accidents, victims are usually want money, for the time unable to work, blah blah blah. And in some cases, victims might give up the lawsuit because it is either taking tooo long, or his/her lawyer suggest to dismiss the case if the case is weak/no chance of winning.
So for you, just hope she doesn't call you or report it to the police. If she does, the police will usually give you a buzz. Be honest and tell them what happened.
Good luck!
