What is “Comprehensive” vs. “Collision” Coverage? (And Which Do You *Really* Need?)

You’re getting an insurance quote. You’ve answered all the questions, and now you’re at the final screen: “Add Collision? Add Comprehensive?” You see the price jump, but you have no real idea what they are. They sound the same. Aren’t they “full coverage”? So you check “yes” on both, grit your teeth at the new price, and just hope you’re protected. Or, if you’re trying to save money on an older car, you check “no,” and secretly pray you never find out what you just declined.

Here’s the hard truth: that one, uniformed click is a high-stakes gamble. Clicking “yes” on a 12-year-old car could mean you’re wasting $500 a year, *every year*, on a policy that will never pay out. Clicking “no” on a 3-year-old car could mean that one slip on black ice—one moment of bad luck—forces you into $20,000 of debt and financial ruin. These are not “throwaway” options. They are the most critical *optional* financial decisions you can make.

As your no-nonsense commuter friend, I’m here to be your translator. We’re going to kill the confusion for good. What do these terms *actually* mean? What do they cover? And most importantly, I’ll give you a simple math test to decide if you *really* need them. Let’s stop guessing and start saving.

What is Collision Coverage? (The “Your Fault” Coverage)

This is the big one. It’s the expensive one. And it’s the simplest one.

Collision coverage pays to repair *your* car when you hit another object and you are at fault.

That’s it. Think of it as “driver error” insurance. It covers you if:

  • You rear-end someone in traffic.
  • You back into a pole or your garage door.
  • You hit a patch of black ice and slide into a guardrail.
  • Someone hits *you* in a parking lot and drives off (a hit-and-run).

This coverage is optional (unless your bank requires it for your car loan). It has a deductible—the amount you pay first. If you have a $1,000 deductible and cause $6,000 of damage to your car, you pay $1,000, and the insurer pays $5,000. Because this coverage is tied to driving skill and accidents, it’s the most expensive optional part of your policy.

What is Comprehensive Coverage? (The “Acts of God & Thieves” Coverage)

This is the other piece of the puzzle. It’s much cheaper than Collision and covers a totally different set of problems.

Comprehensive coverage pays to repair *your* car from almost everything *except* a collision.

Think of it as “bad luck” or “non-driving” insurance. The classic examples are:

  • Your car is stolen.
  • A thief smashes your window to steal your radio.
  • A hailstorm (a huge risk in Alberta) turns your car into a golf ball.
  • A tree branch falls on your car during a windstorm.
  • Your car catches on fire.
  • The Big Canadian One: You hit a deer, moose, or other animal.

This coverage is also optional and has its own deductible (which is often much lower, like $300 or $500). Because these events are “random” and not related to your driving skill, this coverage is usually very inexpensive.

The Big Misconception: “Full Coverage” Isn’t a Real Term

You’ll hear the dealership say, “Don’t worry, you’ve got full coverage.” This is slang, not an insurance product. “Full coverage” is just a lazy way of saying a policy has the “Big 3” components:

  1. Liability (Mandatory: for damage you do to *others*)
  2. Collision (Optional: for damage you do to *your car* by hitting something)
  3. Comprehensive (Optional: for damage done to *your car* by… everything else)

The question isn’t “Should I get full coverage?” The question is “Do the *optional* parts still make financial sense for my car?”

The No-Nonsense Test: Do You *Really* Need Them?

This isn’t an emotional decision. It’s a simple math problem. Grab your phone and a calculator.

Step 1: Find Your Car’s “Actual Cash Value” (ACV)
Go to AutoTrader or Kijiji. Search for your exact year, model, and kilometres. Be honest. What is it *actually* selling for? Let’s say your 10-year-old car’s realistic private-sale value is $6,000.

Step 2: Subtract Your Deductible
Your Collision deductible is probably $1,000.
$6,000 (Car Value) – $1,000 (Deductible) = $5,000.
This ($5,000) is the absolute *maximum* your insurance company would pay you if you totalled your car.

Step 3: Find the Annual Cost of the Coverage
Call your broker or insurer and ask this one simple question: “How much money will I save if I *remove* Collision and Comprehensive from my policy?” Let’s say they tell you it’s $700 per year.

The Final Verdict: The “Break-Even” Test
You are paying $700 per year to protect a $5,000 asset.

Is this a good deal? In this case, probably. But what if your car is only worth $4,000?

$4,000 (Car Value) – $1,000 (Deductible) = $3,000 (Max Payout)

Now, you’re paying $700 per year to protect a $3,000 asset. This is a much worse deal. You would have to go more than 4 years without an accident just to break even on the *cost* of the coverage (4 x $700 = $2,800).

The No-Nonsense Rule: Once your car’s value is low enough that your annual premium for Collision/Comp is more than 20-25% of the *maximum payout*, it’s time to “self-insure.” Drop the coverage and put that $700 a year into your own savings account. That is now your personal “repair fund.”

The Pro-Gamer Move: The “Comp-Only” Strategy

Here’s a smart middle-ground for that $4,000 – $8,000 car. You can have one without the other.



Call your broker and ask to drop Collision, but keep Comprehensive.



This is a brilliant Canadian strategy. Why?

  • Collision is expensive. You are now “self-insuring” for your own driving mistakes (fender benders, sliding into a curb). You are taking that risk.
  • Comprehensive is cheap. For a few dollars a month, you are *still* protected against the “total loss” events you can’t control: theft, fire, or (most importantly) hitting a deer on the highway.

You get to save most of the money, while still protecting yourself from the biggest “bad luck” scenarios.

Ultimately, Collision vs. Comprehensive isn’t a mystery. Collision is for your driving mistakes. Comprehensive is for everything else. Run the math on your car’s value, and you’ll have your answer in five minutes. Stop guessing, and stop overpaying.

Frequently Asked Questions (FAQs)

1. If someone hits me and they are at-fault, which of my coverages pays for my car?
Neither. If the other driver is identified, at-fault, and insured, their Liability coverage pays for 100% of your repairs. Collision and Comp are only for when it’s your fault or no one is at-fault (like a hailstorm).

2. Is a hit-and-run covered by Collision or Comprehensive?
In most provinces, this is a Collision claim. This is a painful one, because it feels like it wasn’t your fault (and it wasn’t!), but because you “collided” with an unknown object/car, it falls under Collision. You will have to pay your deductible, and your rates may go up.

3. My bank says I *must* have both Collision and Comprehensive. Why?
Because you have a car loan or a lease. Until you pay it off, it’s not *your* car—it’s *their* car. They are legally forcing you to buy this coverage to protect *their* asset from your mistakes.

4. Is hitting a deer *really* a Comprehensive claim?
Yes. In 99% of Canadian policies, hitting a live animal is a “Comprehensive” claim, not Collision. This is a crucial distinction. However, swerving to *miss* the deer and hitting a tree *is* a Collision claim. (This is why the practical, no-nonsense advice is always: “Don’t swerve, hit the deer.” It’s safer for you and your insurance.)

5. My Collision deductible is $1,000 but my Comprehensive is $300. Is this normal?
This is not only normal, it’s a very smart setup. Collision claims are more frequent and more expensive, so you have a high deductible ($1,000) to keep your premium low. Comprehensive claims (like a cracked windshield or a deer hit) are less frequent and more “random,” so you keep a low deductible ($300) to make it easy to use.
