This article is for general informational purposes only and does not constitute legal, financial, or tax advice. Selling costs vary by property, lender, and transaction. Consult your lawyer, accountant, and mortgage lender before making any decisions.
Who this is for: Homeowners in Mississauga and the GTA who are getting ready to list and want a clear picture of the real number that lands in their pocket after the sale closes.
Quick Answer
On a $650,000 Mississauga sale with a $380,000 remaining mortgage balance, the net proceeds land at roughly $241,992 before accounting for your mortgage penalty. The number most sellers do not see coming is the HST on the commission, which adds nearly $3,000 to what the commission line actually costs you.
The Question That Came Up the Week Before Their Listing Appointment
A couple I was working with in Mississauga asked me this question: how much money are we actually going to walk away with?
They had bought their home for $500,000. The mortgage balance sitting against it was around $380,000. They had a sense of what it was worth now, somewhere around $650,000. And they needed to know, before listing next week, whether the sale made financial sense for the next step they were planning.
I sat with them and ran every line item. Not just the commission. Every line. When we got to the HST on the commission, there was a pause.
“The number most sellers see on the sheet is not what the agent said plus HST. It is what the agent said, plus HST on that number, plus everything else nobody itemised.”
That pause is why I build this table before any listing conversation, not after.
The Items Most Sellers Either Miss or Misunderstand
Commission and the HST That Comes With It
Commission in Ontario is subject to HST at 13%, as the CRA confirms for real estate agent commissions. This is not optional. It is not a fee you can negotiate out. When an agent tells you their commission rate, the HST is in addition to that number.
On a $650,000 sale at a 3.5% commission rate, the commission is $22,750. The HST on that commission is another $2,957.50. Combined, that is $25,707.50 off the top from commission alone.
Most sellers hear the percentage and assume that is the cost. The HST is the part that shows up on the statement of adjustments and catches people off guard.
The commission rate used in this example is illustrative. Actual commission rates vary by agreement and brokerage. Whatever rate is agreed upon, apply 13% HST on top of the dollar amount of that commission.
Legal Fees on the Sell Side
Sellers pay a lawyer to handle the closing. This typically runs between $1,200 and $2,000 in Ontario depending on complexity, the law firm, and the transaction.
One thing to watch: lawyers sometimes quote their fee and their disbursements separately. Disbursements cover the actual out-of-pocket costs they incur on your behalf, things like title searches, registration fees, and administrative charges. These typically add $300 to $600 on top of the base fee. The $1,500 estimate used in the table in this article is intended to cover both the fee and disbursements combined. When you get your quote, confirm whether the number includes disbursements or not.
Your real number will come from your own lawyer. Get that quote early, before your net proceeds calculation is set.
Your Mortgage Payout and the Discharge Fee
When your home sells, the outstanding balance on your mortgage is paid out from the proceeds before you see a cent. This is not a cost so much as a transfer, but it directly reduces what lands in your pocket.
There is also a discharge fee, sometimes called a mortgage discharge registration fee, which covers the administrative and legal cost of removing the mortgage from title. Lenders and lawyers handle this. It is typically in the range of $200 to $400.
The Mortgage Penalty: The Cost That Can Change Everything
Here is the number most sellers do not have when they first ask the net proceeds question: the mortgage penalty.
If you are breaking your mortgage before the end of its term because you are selling, your lender will charge a penalty. How much depends on whether your mortgage is variable or fixed, how much time is left on the term, and your specific lender’s calculation method.
Variable rate mortgages typically charge three months of interest. Fixed rate mortgages use the greater of three months of interest or an interest rate differential calculation, which can be several thousand dollars depending on the rate environment when you signed.
The upside is that knowing your penalty before you list lets you factor it into your net number with confidence. The trade-off is that many sellers skip this step and only get the real number from the lender during the closing process, when it is too late to adjust their plans.
Call your lender before you list. Ask for a payout statement with a penalty figure calculated for your anticipated closing date. This is a free conversation and it is the single most important number you do not yet have.
Mortgage portability is also worth asking about in the same conversation. If you are buying another home after selling, you may be able to port your existing mortgage to the new property, which can reduce or eliminate the penalty depending on your lender’s rules.
Closing Adjustments
The statement of adjustments settles any costs that have been paid in advance or owed between buyer and seller at closing. Property taxes paid ahead, any condo fees, or utility prepayments get balanced here. This is typically a small number but it appears on every closing statement.
What About Land Transfer Tax?
Land transfer tax in Ontario is a buyer cost, not a seller cost, as confirmed by ontario.ca. If you are selling, you are not paying LTT. The buyer pays it on the purchase. This is a frequent point of confusion and worth stating clearly: it comes off their side, not yours.
One More Conversation to Have Before You List: Your Accountant
This one does not appear on the statement of adjustments, but it can affect your overall financial position after the sale, so it is worth flagging.
If the home you are selling has been your principal residence every year since you bought it, the capital gain on the sale is generally not taxable under the CRA principal residence exemption. For most owner-occupied Mississauga homeowners, this applies and no tax is owed on the gain.
Where it gets more complicated is if you rented out a portion of the property at any point, claimed a home office deduction, or the home was not your principal residence for part of the ownership period. In those situations, a portion of the gain may be taxable and needs to be reported on your tax return.
This does not change the net proceeds calculation at closing. But it can change what you keep after tax. If any of those situations apply to your property, a short conversation with your accountant before you list is worth the time. The CRA principal residence exemption rules are the governing reference for this question.
The Full Picture: Estimated Net Proceeds on a $650,000 Mississauga Sale
This table uses the actual scenario Gaurang ran for a Mississauga couple before their listing appointment. Figures are illustrative based on the details provided. Your numbers will differ based on your actual mortgage balance, your commission agreement, your legal fees, and your mortgage penalty.
| Cost Item | Amount |
|---|---|
| Sale price | $650,000 |
| Commission at 3.5% | $22,750 |
| HST on commission at 13% | $2,958 |
| Seller legal fees and disbursements (estimated) | $1,500 |
| Remaining mortgage balance | $380,000 |
| Mortgage discharge fee | $300 |
| Closing adjustments (estimated) | $500 |
| Mortgage penalty | Confirm with lender before listing |
| Estimated net proceeds (before penalty) | ~$241,992 |
Table notes: Commission rate of 3.5% is illustrative. Your rate is set in your listing agreement. HST at 13% applies to the commission amount. Legal fee estimate covers both fees and disbursements combined. Mortgage penalty is not included and must be confirmed from your lender’s payout statement before listing. All figures in Canadian dollars.
You now know every line item that sits between your sale price and the amount that actually lands in your pocket: commission, HST on that commission, legal fees, your mortgage payout, the discharge fee, and the closing adjustments most sellers never think about. What you do not have yet is your personal number. Your sale price, your mortgage balance, and your commission agreement produce a specific net figure, and that figure is different for every property and every seller. That is the ten-minute conversation.

Why Running This Math Before the Listing Changes the Conversation
When sellers see this table for the first time before listing, something shifts. The question stops being about the sale price and starts being about the net number.
That is actually a more useful question. Because the sale price you accept is not the number you use to plan your next move. The net number is.
If you are selling to buy a larger property, your net proceeds become your down payment on the next home. If the penalty, the legal fees, and the HST on commission reduce that number more than you expected, the conversation about what you can afford on the next purchase changes.
Running this calculation before listing means you can price your home with a clear target in mind, choose your listing timing to avoid a penalty-heavy closing window if possible, ask your lender about portability before you have an offer in hand, and brief your lawyer on the transaction before you get to closing day.
None of this is difficult. It is a matter of running the numbers first instead of last.
What This Means for You
If you are planning to sell in Mississauga or anywhere in the GTA, the most useful thing you can do before your listing appointment is build this table with your actual numbers. Start with your expected sale price, your real mortgage balance, and your agreed commission rate. Then call your lender for a payout statement with a penalty figure. That one phone call is the difference between a net number that surprises you on closing day and one you have already planned around.
The HST on commission is not a small line. On most Mississauga sales, it adds $2,500 to $4,000 to your selling costs. Knowing that number before you list is the baseline for any honest conversation about what you can do with the proceeds.
Key Takeaways
- Commission in Ontario is subject to 13% HST. That adds roughly $2,958 on a $650,000 sale at a 3.5% rate. It belongs in your net proceeds table.
- Land transfer tax is a buyer cost, not a seller cost. Legal fees, disbursements, the discharge fee, and closing adjustments are seller costs. Budget $2,000 to $2,500 combined for the legal side as a starting estimate.
- The mortgage penalty is the number most sellers do not have. Call your lender before listing and ask for a payout statement.
- Net proceeds, not sale price, is the number that governs your next move. Build the table before the listing appointment, not after.
- If you rented out part of the property or it was not your principal residence for the full ownership period, speak to your accountant before listing. The principal residence exemption may not fully apply and there could be a tax component to the sale.
The Bottom Line
Selling a home in Mississauga is not just a sale price conversation. It is a net proceeds conversation. The gap between the two is real, it is itemised, and every seller deserves to know it before they list.
The risk is not that the market is bad for sellers right now. The risk is walking into a listing appointment without a clear picture of the dollar amount that actually lands in your hands. That number determines everything that comes next.
Frequently Asked Questions
Does the seller pay land transfer tax in Ontario?
No. Land transfer tax in Ontario is paid by the buyer, not the seller. When you sell your home, you are not paying LTT. The buyer pays it based on the purchase price.
How is HST calculated on real estate commission in Ontario?
Real estate commission in Ontario is a taxable service subject to HST at 13%. The HST is calculated on the dollar amount of the commission, not on the sale price. On a $22,750 commission, the HST is $2,957.50. The seller pays both the commission and the HST on that commission.
What is a mortgage penalty and when does it apply?
A mortgage penalty applies when you break your mortgage before the end of its term. Most sellers trigger this because they are selling the property before the mortgage renews. Variable rate mortgages typically charge three months of interest. Fixed rate mortgages charge the greater of three months of interest or an interest rate differential. Your lender calculates the exact penalty and provides it in a payout statement.
Can I avoid a mortgage penalty when selling my home?
In some cases, yes. If your mortgage term ends close to your closing date, you may be able to close within the renewal window and avoid the penalty. You may also be able to port your mortgage to a new property if you are buying at the same time, which can reduce or eliminate the penalty. Ask your lender about both options before you list.
How accurate are the net proceeds estimates in this article?
The figures used in this article are based on a real Mississauga scenario with confirmed details: sale price $650,000, remaining mortgage balance approximately $380,000, commission rate 3.5%. The commission rate and legal fee estimates are illustrative. Your actual selling costs will vary. The most important number to verify independently is the mortgage penalty, which must come directly from your lender.
Do I pay tax when I sell my home in Ontario?
If the home has been your principal residence every year since you bought it, the capital gain on the sale is generally exempt from tax under the CRA principal residence exemption. If you rented out part of the property, claimed a home office deduction, or the home was not your principal residence for some of the ownership period, part of the gain may be taxable. Confirm your specific situation with your accountant before listing. The governing reference is the CRA principal residence exemption rules at canada.ca.
You now understand why the sale price and the net number are two different conversations, and you know which costs most sellers miss before their listing appointment. The one thing you do not have yet is your actual net figure built from your real mortgage balance, your commission agreement, and your lender’s penalty number. That is the calculation I run before every listing conversation, and it takes less time than you think.
Ready to List? Let’s Run Your Real Net Number First.
Most sellers come to their first listing appointment with a price in mind. The most useful thing I can do before that appointment is build the complete statement with you: commission, HST on commission, legal fees, mortgage payout, penalty, and what lands in your hands.
