According to the Insurance Act, if you're planning on filing a claim, you have seven days from the time of the incident to report it. If not, no report is required UNLESS the insurance policy says "you must report all damage or collisions." That's rare, though. Check your policy.

Unless a driver was charged with an offence, no.
Another example: My car got banged up in a parking lot in two separate hit-and-run incidents (Note to Toronto drivers: STOP HITTING MY CAR!!
) one of which gouged and wrecked the right rear quarter-panel and the other buckled and dislocated the front bumper. No surveillance cameras, no chance of identifying the driver or the suspect vehicle, so I'm paying out of pocket rather than dealing with insurance and having my rates go up for the next six years (did the math, cheaper to pay out of pocket). So, I didn't bother reporting it to my insurance company, as far as putting in a claim goes.
