I accidentally bumped into some one else's car in a parking lot. Left a scratch?

I was backing out my car in a narrow parking lot right outside my gym. I accidentally bumped into a rather new white Ford SUV that was parked beside a curb because the driver was waiting for her daughter. It ended up leaving a scratch on its front left bumper that was about 2 inches long, without any dents. Unfortunately the driver was in the car at that very moment. Immediately after the bump, I moved my car out the way, turned off the engine and approached the lady and apologized to her many times, asked if she was okay. Thankfully she was not hurt, but was not happy. I offered to pay for the damage and we exchanged our personal and my insurance info. I suggested using a car scratch repair but she claimed this vehicle is a leased vehicle so she wants to keep it in perfect condition and prefers to get it professionally fixed.
Does anyone know how much a scratch like that would cost professionally? Also is there anything else I should be aware of e.g. If there's anything she could charge me for or if this incident could raise my insurance?

P.s. I live in the Greater Toronto Area in Ontario

Just hope your insurance don't go up!

You did your part by exchanging insurance info. The rest is up to her insurance company.

A 2 inch scratch is nothing. Pay for it out of your pocket instead of filing an insurance claim. Any claim against your insurance could be cause for your rates going up. I find it interesting that you say unfortunately the driver was in the car. If she wasn't would you have just driven off?

Take pictures of the damage and get a police report. Then let the insurance company do it's job. Or, learn the hard way, like I did.

Offer to have it fixed at her boby shop of her choice and rem b er use both mirrors and check what is around you
