Best Realtor in Lisgar, Mississauga (2027): How to Choose

By Jatin Dua · Broker of Record, RE/MAX Quantum Realty · Updated 2 November 2026 · 9 min read — How to choose a real estate agent in Lisgar, Mississauga for 2027: city prices, basement water history, questions to ask and red flags.

This guide is for Lisgar homeowners who may sell in 2027 and for buyers looking at houses in northwest Mississauga. You will get verified city price numbers, a plain account of the area’s basement water history and what the City is doing about it, the questions to ask an agent, and the red flags to avoid.

Where is Lisgar, and what shapes home values there?

Lisgar is a neighbourhood in Mississauga’s Ward 10, in the northwest of the city. The ward runs from Churchill Meadows north to Meadowvale. Lisgar’s streets include Osprey Boulevard and Doug Leavens Boulevard, and the Osprey Marsh sits inside the community.

The neighbourhood gave its name to Lisgar GO station, on the Milton line at 3250 Argentia Road near Tenth Line. It opened on 4 September 2007 and has 788 parking spaces. Highways 401 and 407 meet close by, which matters to drivers working in Mississauga’s business parks or heading toward Milton.

Three things shape a Lisgar sale more than anything else:

• Home type and condition. Price depends on whether it is detached, semi or a townhouse, and how well it has been kept.
• The basement. Its finish, any second unit, and its water history.
• Location within Lisgar. Distance to the GO station, schools and main roads.

The second point is where Lisgar is different from most of the GTA, so this guide spends time on it.

What are Mississauga home prices doing heading into 2027?

There is no reliable public median for Lisgar alone, and I will not invent one. Here are verified city-wide numbers. Lisgar has several of these home types, so treat them as context, not a price for your house.

Semis and freehold towns are down about 7% city-wide. Every home type is also taking longer to sell than a year ago. In October 2026 alone, TRREB counted 200 detached sales in Mississauga at a median of $1,150,000, with homes taking an average of 32 days to sell. Add the Bank of Canada’s rate hike to 2.50% on 28 October 2026, and buyers have reasons to be careful. In Lisgar, careful buyers ask about water.

What happened with basement flooding in Lisgar?

Lisgar has a long, public history of water getting into basements. Here is what the record shows:

• 2008 to 2013: more than 180 homes were damaged, according to The Pointer’s review of the history.
• The cause: a 2015 City report tied the problem mainly to groundwater collecting in the bedding of the trenches that carry sewer pipes. The area’s soil drains slowly, so water can build up and reach home weeping tiles during heavy storms. The Pointer also notes Lisgar was built on former marshland.
• Summer 2024: two major storms hit, and about 500 homes in Ward 10 flooded, per the same report.

Not every Lisgar home has had water, and many never have. But buyers know the history, and a good agent plans for the question instead of hoping it will not come up.

What is the City doing about it, and when?

The City’s answer is a set of pumping stations that pull water out of the pipe trenches and foundation drains. As of the latest public updates:

• Station 1, at the Cactus Gate parkette on Black Walnut Trail, has run since spring 2021.
• Station 2 is operating, and Station 3 was expected to open in 2026, per The Pointer in September 2025.
• Station 4, along the tributary at Osprey Boulevard, has $5.6 million approved. The City said construction was expected to start in 2026 and that it would not be delivered until 2027.

Dates like these can move, so check the City’s Lisgar project page and your ward councillor’s updates for the current status before you buy or list.

How should a Lisgar seller handle a past water problem?

Honestly, and on paper. Buyers will hear about Lisgar’s history from their own agent, their insurer or a neighbour. The question is whether they hear your side with proof.

• Gather records. Dates of any water events, insurance claims, repair invoices, and receipts for work such as sump pumps or waterproofing.
• Know what a seller statement does. RECO explains that your agent may ask you to fill out a property information statement. If it is meant for buyers, your agent must tell every interested buyer it exists and give a copy to any buyer who asks. If it is only for your agent, that must be clear.
• Talk to your lawyer about what you must disclose. Hiding a known problem can come back to you after closing.

How can a Lisgar buyer protect themselves?

• Ask direct questions in writing: has the basement ever had water, when, and what was done?
• Make the offer conditional on a home inspection, and ask the inspector to look closely at the basement and grading.
• Call your insurer before you firm up. My guide to the insurance condition in Ontario explains how to build that check into your offer.
• Check any second unit. Mississauga requires second units to be registered, and it publishes a registry list updated monthly. If a unit is not on the list, it is not registered.
• Read the City’s updates. Knowing which pumping stations are running near the street, and which are still to come, helps you judge the risk for yourself.

Also think about how you will use the basement. A fully finished lower level with a rental unit has more to lose from water than a basement used for storage and laundry. Price that difference into your offer, and budget for any work the inspector suggests. None of this means you should avoid Lisgar. It means you should buy with your eyes open, the same way you would in any older neighbourhood with a known issue.

What questions should you ask a Lisgar realtor before hiring?

1. Which recent sales are you comparing my home to, and how did you adjust for basement finish and condition?
2. How will you handle questions about Lisgar’s water history?
3. Do you know the status of the City’s pumping station work near my street?
4. Will you prepare a document package for buyers, and what goes in it?
5. If my home has a second unit, can you confirm it is on the City’s registry?
6. With homes taking about a month to sell, what is your plan if there are no offers by week three?
7. What is your fee, what does it include, and how long is the holdover period?

How is a realtor paid when you sell in Lisgar?

RECO says you and the brokerage decide the fee. It is not set by RECO, the government or any real estate board. It can be a fixed amount, a percentage or both, but it cannot be based on the gap between list price and sale price. Your agreement must show the expiry date clearly on the first page and should list the services you are paying for. If it has a holdover clause, agree on its length before you sign. Read my guide to representation agreements in Ontario before you commit.

What are the red flags when choosing a Lisgar agent?

• “Don’t mention the flooding” as a pricing strategy.
• No questions about your basement at the first meeting.
• Calling a second unit “legal” without checking the registry.
• A price far above recent sales, with no written reasons.
• Pressure to sign a long agreement before you compare anyone.
• Not registered, or a recent discipline record, on RECO’s public register.

Should you hire a Lisgar local or a GTA-wide agent?

You want someone who knows Lisgar’s streets and its history, and who also knows where your buyers are coming from. Many will be comparing your home with Churchill Meadows, Meadowvale and Milton. A buyer who has toured three houses in Churchill Meadows the same weekend will compare your price, finish and lot with those, not with an old sale on your street. Your agent should know those markets well enough to explain why your home is the better buy, and should be able to answer water questions without getting defensive. For those neighbouring areas, see my guides to the best realtor in Churchill Meadows and the best realtor in Meadowvale.

What to do next

1. Pull together any water history, insurance claims, repair invoices and waterproofing receipts.
2. Check the City’s Lisgar project page for the latest pumping station status.
3. Interview two or three agents with the same questions, and check each on RECO’s register.
4. Ask each for a written price plan and a buyer document package outline.
5. Before signing, confirm the fee, expiry date, holdover period and services in writing.
