The short answer
Home insurance in Scarborough has to fit the area's housing: 1950s to 1970s detached homes and semis, basement apartments, multigenerational families and properties near the Bluffs and ravines. Sewer backup coverage matters on many streets. As an independent broker, I compare 12+ insurers to find a policy that matches how your Scarborough home is actually used.
From Wexford to Malvern to the Guild, I help families buy home insurance in Scarborough that matches how their house is built, lived in and shared.
Much of Scarborough was built out in the decades after the Second World War: brick bungalows in Wexford and Dorset Park, side-splits and semis in Agincourt and Birch Cliff, and newer subdivisions in Malvern, Morningside Heights and the Rouge area. Many of those homes now hold more than one household, with a basement apartment or extended family under one roof. As an R.I.B. (Ontario) licensed broker, I compare 12+ insurers to build home insurance that reflects the way your home is really used.
Insurers price risk on the details you give them, so accuracy matters. A finished basement rented to a tenant, three generations living together, or an older home with original plumbing all change the right policy. I ask the right questions up front, add the water coverages Scarborough basements need, and give you a same-day quote. If you also drive, see my Scarborough auto insurance page as well.
A 1950s or 1960s Scarborough bungalow is usually solidly built, but insurers want to know what has changed since then. Expect questions about the roof's age, electrical service size and panel, plumbing materials, the heating system and whether there's an old oil tank on the property. Homes from this era may still have galvanized steel supply lines or original cast-iron drains, and some homes from the mid-1960s to mid-1970s were built with aluminum branch wiring. None of these automatically disqualifies a house, but each can affect which insurers will quote and on what terms.
For semi-detached homes, I also look at the shared wall. A fire or water loss that starts next door can spread to your side, and the reverse is true too, which is why a strong personal liability limit matters for semis. If you've updated the roof, wiring or plumbing, keep the invoices or permits handy. Documented upgrades are one of the most effective ways to widen your options and improve pricing.
Basement apartments are everywhere in Scarborough, and they're one of the most common reasons a homeowner's policy doesn't respond the way the owner expected. If you rent out a basement unit or second suite, your insurer needs to know. Renting part of the home changes the risk, and insurers handle it with a specific endorsement or a different policy form that addresses rental income, liability to the tenant and their guests, and damage the tenant causes. Your tenant should carry their own tenant insurance for their contents and liability, and you can make that a condition of the lease.
Multigenerational households raise different questions. Parents, grandparents and adult children living together are usually fine under one policy if they're related and share the home, but I confirm who counts as an insured, whether jewellery and heirlooms are scheduled, and whether the contents limit reflects several generations' worth of belongings. A self-contained suite occupied by a relative may still need to be disclosed and set up properly.
Sewer backup is the water claim I talk about most with Scarborough homeowners. In heavy rain, older municipal systems can surcharge and push water up through floor drains into finished basements, and if there's a rental unit downstairs, the loss affects your tenant too. Sewer backup and overland water are usually separate optional coverages, so I confirm both. The City of Toronto has offered a basement flooding protection subsidy for items like backwater valves, so it's worth checking current eligibility. Near the Scarborough Bluffs and ravines such as Highland Creek and the Rouge, remember that most home policies exclude erosion and earth movement, so slope and setback concerns need a separate conversation.
Your Scarborough premium depends mainly on the house and how it's used. Insurers look at the rebuild cost, year built, update years for the roof, wiring, plumbing and heating, the construction type and whether part of the home is rented. Your claims history, especially past water claims, carries real weight, as do your deductible and the water coverages you add. Backwater valves, sump pumps, monitored alarms and leak sensors can help. A home and auto bundle usually lowers both premiums. My guide on home insurance costs in Ontario explains each factor, and I compare 12+ insurers so you see the real range for your address.
I disclose and structure basement apartments and second suites properly, so a claim involving your tenant or rental unit isn't put at risk by a missing endorsement.
I add sewer backup and overland water at sensible limits for Scarborough basements and point out the upgrades that can improve your eligibility and your price.

Common questions about home insurance in Scarborough. Don’t see yours? Just call or send the form.
Yes. Renting part of your home is a material change, and not disclosing it can put a claim at risk. Most insurers cover it with a rental endorsement or a specific policy form. I'll set it up correctly and recommend that your tenant carry their own tenant insurance too.
Usually not by default. Sewer backup is an optional endorsement with its own limit and sometimes its own deductible. For a Scarborough home with a finished basement or a rental unit, I recommend it almost every time. My guide on water damage coverage explains what's included and what isn't.
Generally no. Most home policies exclude erosion, landslide and other earth movement, so gradual loss of land near the Bluffs or a ravine slope isn't covered. Sudden insured perils such as fire or wind still are. If your property sits near a slope, I'll explain exactly where the policy lines fall.
In most cases, yes, if they're relatives living in the home with you. I confirm they're included as insureds, that the contents limit accounts for their belongings, and that items like jewellery are scheduled. A self-contained suite may need separate treatment, so tell me how the home is laid out.
Usually the same day. Have your year built, update years for the roof, wiring, plumbing and heating, and details on any rental unit ready. Call (437) 474-1333 or request a quote online, and I'll compare 12+ insurers for you.
