Do you need home insurance on a brand-new build in Ontario?

Yes. A newly built home in Ontario still needs its own home insurance policy, and your mortgage lender will require proof of it before you take possession. Ontario's Tarion new-home warranty covers construction defects, but it is not insurance and will not pay for fire, theft, water damage, or a liability claim. Those risks are yours from day one.

Is a new build cheaper to insure than an older home?

Usually, yes, and it comes down to risk. Everything in a new home is up to the current building code: fresh wiring, new plumbing, a new roof, modern heating, and often fire-resistant materials. Insurers see fewer of the problems that drive claims on older properties, such as failing knob-and-tube wiring, galvanized pipes, or a roof near the end of its life.

Because of that lower risk, many insurers offer a "new home discount" that gradually tapers off as the home ages. It is common but not universal, so it is worth asking whether the market you are placed with offers one. The exact savings depend on the insurer, your location, the rebuild cost, and your claims history, so treat any discount as a nice-to-have rather than a guarantee.

That said, "newer" does not automatically mean "cheapest." A large custom home with high-end finishes can cost more to insure than a modest older house simply because it would cost more to rebuild. Insurance is priced on what it takes to put your home back the way it was, not on its age or its purchase price.

What does a new-build home insurance policy actually cover?

A standard Ontario home policy on a completed new build generally includes the same core pieces as any other home policy:

Dwelling coverage pays to repair or rebuild the structure itself if it is damaged by a covered loss such as fire or a burst pipe. Contents coverage protects your belongings. Personal liability protects you if someone is injured on your property or you accidentally damage someone else's. Additional living expenses help cover the cost of somewhere to stay if a covered loss makes your home unlivable while it is repaired.

Two things are worth flagging on a new build specifically. First, water coverage is not automatic. Sewer backup and overland water are typically optional endorsements you add, and a new home in a new subdivision is not immune to a heavy storm or a plumbing failure, so it is usually worth the conversation. Second, if you are building in high value finishes, a home office, or a finished basement right away, make sure the policy reflects that so you are not underinsured at claim time.

Do I insure it based on the purchase price or something else?

Neither the purchase price nor the market value. Home insurance is built around rebuild cost, which is what it would cost to reconstruct your home with today's labour and materials on your existing lot.

On a new build this matters because the price you paid often bundles in the land, the builder's profit, and development costs that have nothing to do with rebuilding the structure. In some markets the rebuild cost is lower than the purchase price; in others, where construction costs are high, it can be surprisingly close. A broker will usually run a replacement-cost estimate using the home's size, layout, and finishes so the dwelling limit is set correctly from the start. Getting this right protects you from being underinsured, and from paying for coverage you do not need.

What if the home is still under construction when I own it?

This is the part people miss. A standard home insurance policy is designed for a home that is finished and occupied. If you own the lot and the home is still being built, that construction phase is normally handled by a different type of coverage, often called course of construction or builder's risk, which protects the structure and materials while work is underway.

For most buyers of a production or subdivision home, the builder carries the construction-phase coverage and you are not buying a home policy until closing. But if you are the one commissioning a custom build, doing an owner-build, or taking early possession before the home is fully complete, talk to a broker early so there is no gap between the construction phase and your homeowner policy. Gaps in coverage during a build are a common and expensive surprise.

When do I need to have the policy in place?

Before you take possession, not after. Your lender will ask for proof of insurance, sometimes called a binder or confirmation of insurance, before they release the mortgage funds, and they will want to be listed as the mortgagee on the policy. That confirmation usually needs to be in the lender's hands a few days ahead of your closing date, so it is smart to line up your quote a couple of weeks out rather than the day before.

If your closing date slips, which happens often with new construction, just let your broker know so the policy start date can be moved to match. You want the coverage to begin the moment the home becomes your responsibility.

One more timing note: if you close on the home but do not move in right away, tell your broker. A home sitting empty for an extended stretch can trigger vacancy conditions that limit coverage, and it is far better to sort that out in advance than to discover it after a claim.

Is a new condo different from a new freehold home?

Yes. If your new build is a condo, the condo corporation carries a master policy that covers the building's common elements and, typically, the original standard unit as it was built. You still need your own condo unit owner's policy for your belongings, your personal liability, any upgrades or improvements you make to the unit, and coverage for things like a special assessment or your loss of use. New condos and freehold homes both need personal coverage; the split of responsibility is just different, so make sure your broker knows which one you are buying.

FAQ

Does Tarion warranty replace home insurance in Ontario? No. Tarion protects you against defined construction defects and certain deposit and delayed-closing issues on new homes, but it does not cover fire, theft, water damage, or liability. You need both: the warranty for defects and a home insurance policy for everyday risks.

Can I get a discount just because my home is new? Often, yes. Many insurers offer a new-home discount that reduces as the home ages, but it is not offered everywhere and the amount varies. It is one factor among many, so the best approach is to compare options rather than assume a specific saving.

When should I start shopping for coverage on my new build? Start about two weeks before your closing or possession date. That gives time to set the rebuild cost correctly, add any water or other endorsements you want, and get the confirmation of insurance to your lender before they fund the mortgage.
