The first hour, at the roadside
Before anything becomes a claim it is a situation on a road. Move the vehicles clear of live lanes if they will move — the 401 and the DVP are not places to stand beside a bumper debating fault. Hazards on. Nobody argues about who did what; that gets decided later by a rulebook and not by whoever speaks loudest at the roadside.
Then collect what the claim will need, because you will not be able to go back for it. Names, licence numbers, plate numbers, the name of each driver’s insurance company and policy number. Photographs of both vehicles from four corners, wide enough to show the road and the lane markings, plus close shots of every contact point. A photo of the other driver’s licence and pink slip saves an argument later. If anyone stopped to help, ask for a phone number.
If anyone is hurt, that is a 911 call from where you are standing, and you wait for police. It is a separate duty from the paperwork one and it does not get traded for a drive somewhere later. Where nobody is injured, the report goes to a Collision Reporting Centre instead — Toronto directs drivers to 32 Division in North York or 41 Division in Scarborough, and York Region runs centres in Richmond Hill and Markham. Go to the nearest one promptly, generally within twenty-four hours, when the combined damage looks likely to pass the provincial reporting threshold or the other driver left without giving you anything.
Day one: the notification and the claim number
Call your own insurance company even if you are certain the other driver caused it, and even if you have not decided whether to repair anything. The standard Ontario policy expects to hear from you promptly — think within about a week, not whenever the schedule clears. Telling them is not the same as committing to a claim.
What you get back is a claim number, and that number is the spine of everything after it. Write it somewhere you will not lose it. Every shop, adjuster, rental branch and tow invoice will ask for it. Start a simple log at the same time: date, who you spoke with, what they said. Three weeks in, when someone says nobody told you about a deductible, the log settles it in seconds.
You will also be asked how the collision happened. Describe what you saw and where the vehicles ended up. Do not estimate speeds you did not read off the dash, and do not volunteer conclusions about fault — that is not your job in this process.
Fault is decided by a rulebook
Ontario assigns fault through the Fault Determination Rules, a set of scenarios with diagrams. The adjuster matches your collision to the closest scenario and applies the result — none, a quarter, half, three quarters, or all of it. Whether the other driver apologized at the scene, and whether anyone got a ticket, does not directly control the outcome.
Fault matters to you for two practical reasons. It decides whether your deductible applies, and it decides whether a rental is covered as part of the claim or only under a loss-of-use endorsement you may or may not have. If you are found entirely not at fault, your own insurance company still handles the vehicle damage — that is direct compensation, and it is why calling your own company is correct even when someone else caused it.
If the fault decision looks wrong to you, say so in writing early, with your photographs attached. It is far easier to have a determination reconsidered in week one than in month three.
Choosing the shop, and what you are signing
This is the point where you pick a shop, and the choice is entirely yours. Photographs of the damage are enough for a written estimate, so the claim can move before the car does. If the car is not drivable we help coordinate the tow — we are not a tow company, but you choose where the vehicle goes, and it should go to the shop that will repair it rather than to a compound that bills storage.
At drop-off you sign a repair authorization. That document lets the shop begin work and, usually, lets the insurance company pay the shop directly. It is not a blank cheque: it authorizes the estimate as written. Anything found later needs its own approval, which is exactly how it should work.
Sort the rental at the same time. If it is coming through your coverage or through the not-at-fault claim, book it to start on the drop-off date rather than the collision date, so you are not burning entitlement while the car sits in your driveway waiting for parts to land.
Teardown, approval, paint, and the drive home
The car goes on a bay and comes apart. Almost every repair beyond a cover-and-blend produces a supplement — a revised estimate with the damage that only appears once the panel is off. Photographs go to the adjuster, the extra lines get approved, and only then are the additional parts ordered. That approval window is the most common cause of a repair taking longer than the first estimate suggested, and it is nobody’s failure; it is the sequence.
Then the physical work: structural pulls and measurement if the car needs them, panel fitting, prep and priming, colour matched against a spray-out card rather than a code alone, clear coat, bake, cut and polish, reassembly. Wheel alignment where suspension or structure was touched. A post-repair scan, and a radar or camera recalibration if the vehicle needs one after bumper, windshield or mirror work.
On the last day you pay your deductible directly to the shop if one applies, return the rental, and take the file: the final invoice, the parts list, the warranty document and the before photos. Put it with your ownership. Years later, when a buyer runs a history report and finds the claim, that folder is what turns a red flag into a documented repair.
Questions people ask
Do I have to get an estimate from my insurance company first?
No. A shop estimate can be submitted directly, and an appraiser may then review it or come look at the vehicle. Waiting for an appraisal before anyone writes anything usually adds days. Send photographs to the shop the same day and let the two documents meet in the middle.
How long after the collision can I still open a claim?
Your policy expects prompt notice, so call within days rather than weeks. Separately, Ontario allows two years from the date of the collision to start a property-damage lawsuit. Those are different clocks: leaving the insurance notification late can create coverage problems even while the litigation window is still open.
What if the other driver wants to settle without insurance?
It happens, and it sometimes works out for very light damage. The risk is that hidden damage appears at teardown, the private agreement no longer covers it, and by then you may have missed the window for prompt notice. At minimum, report the collision to your own insurance company as information, even if you never claim.
Can I take the car home while I wait for the parts?
Often yes, if it is safe to drive and nothing structural has been disturbed. Ask the shop rather than assuming — a car with a missing reinforcement bar or a disabled sensor is not the same car you drove in. Booking the bay for when parts land is usually better than parking in a repair queue.
