When you cancel a home or car insurance policy, you’ll get a refund. The refund amount depends on how much term remains on the policy and whether the insurer uses the pro-rata or short-rate method to calculate refunds.
Pro-rata refunds are based entirely on the remaining term, while short-rate refunds deduct an additional penalty.
On this page, you’ll learn how pro-rata and short-rate refunds work, and what you need to know when you cancel your home or car insurance policy early.

The important points
When you buy a home or car insurance policy, it usually has a one-year term.
Insurance premiums are pre-paid; whether you pay monthly or annually, you’re paying for future coverage. At the time you make your payment, it’s called unearned premium. As time passes and your policy term runs out, your insurance provider earns the prepayment, converting it into earned premium.
If you cancel your insurance policy before the policy term ends, you’ll usually get a refund. But you probably won’t get a full refund. Instead, your refund will be calculated based on two factors:
Part one is straightforward. If your policy has a one-year term and you cancel after six months, you might expect a refund of all unearned premiums — in this case, 50%. That would be a pro-rata refund. A pro-rata (or prorated) refund is based solely on the remaining policy term.
The next part is where it can get complicated.
Many home insurance policies impose a penalty for cancelling early. This is called a short-rate refund. Depending on the provider and policy, the penalty might be a set percentage, or one that scales based on the remaining term. For example, the short-rate penalty could be 5% with 12 months remaining but only 0.5% with one month remaining.
Example: calculating pro-rata cancellation
You buy a car insurance policy for $1,500 on a one-year term.
After three months, you sell your car and cancel your policy early. Three months out of twelve is 25%, so your $1,500 payment is now $375 in earned premium and $1,125 in unearned premium.
When you cancel, your insurer refunds you the $1,125 in unearned premiums, representing the nine months of prepaid coverage that you didn’t use.
Example: calculating short-rate cancellation
Same situation: you’re cancelling your $1,500 policy after three months.
But this time, your insurer imposes a short-rate cancellation penalty. Their short-rate table says that the penalty for cancelling after three months is 5%. So instead of refunding you 75%, they refund you 70%, which is $1,050.
Basically, you’ve paid a $75 short-rate penalty compared to the pro-rata refund.
No matter which method your insurance provider uses, the cancellation terms will be spelled out in your policy documentation.
Even when your provider offers pro-rata refunds, you may encounter the minimum retained premium (MRP), also known as the minimum earned premium.
Basically, this is the premium that the insurer earns simply by issuing the policy. It represents the costs incurred for writing a policy, like data retrieval fees or employee salaries. For example, home insurance policies from Square One feature a $50 MRP.
After you’ve paid at least that much in premiums, you’ll receive a refund of all unearned premiums if you cancel. The MRP only applies if you cancel before you’ve paid at least the minimum amount. In that case, your refund will simply have the MRP deducted.
A minimum retained premium isn’t a fee. It just means that the first portion of your premiums is non-refundable.

Every insurer is different with regards to their cancellation policies. Even different types of insurance from the same provider may have different cancellation terms.
Generally, you’re most likely to receive a pro-rata refund:
And you are most likely to receive a short-rate refund:
Short-rate cancellation penalties are permitted in every province for both home and car insurance. They’re standard practice for almost all providers. Even the public insurers in BC, Saskatchewan, and Manitoba charge either cancellation fees or short-rate penalties in many situations.
There are some situations, like insurer-initiated cancellations, in which short-rate penalties aren’t allowed. Sometimes, insurers are willing to waive cancellation penalties, such as when someone cancels their policy because they’ve sold their car or house, or if they’re moving to a new province or country.
Square One doesn’t charge a short-rate penalty for any cancellations, whether home or car insurance. However, a minimum retained premium of $50 does apply to most policies in their first year.
Most of the time, if your insurer charges a short-rate fee for cancelling your policy, there’s no way around it. The only way to avoid it would be to wait and cancel your policy on the renewal date at the end of the term.
However, some providers will waive the fee under reasonable circumstances. For example, if you’ve sold your car and don’t plan to replace it, or if you’re facing unusual financial hardship. If you’re moving to another province, your insurer might offer you better refund terms if you buy another policy from them in the new province.
Each provider sets their own short-rate cancellation fees, but they usually fall somewhere between 1% and 10% for home and car insurance. Many providers have scaling short-rate tables that reduce the penalty as the policy term passes. Others simply charge a flat cancellation fee regardless of the remaining term.
