Home insurance in Ontario is not optional for buyers financing a purchase, your mortgage lender requires proof of insurance before releasing funds on closing day. But beyond the lender requirement, home insurance is one of the most important financial protections a Markham homeowner carries. Understanding what your policy covers, what it excludes, how your premium is calculated, and what you need to have in place before closing day protects you from the moment you take possession of your Markham home. Michael John Lau and Neeraj Moolchandani at Kaizen Real Estate Team walk every buyer through this as part of closing day preparation.
What Home Insurance in Ontario Actually Covers
A standard Ontario home insurance policy is made up of several distinct coverage components. Understanding each component, and what it specifically protects, helps Markham homeowners make informed decisions about their coverage limits and optional endorsements.
Covers the physical structure of your Markham home, walls, roof, foundation, attached garage, built-in appliances, against insured perils. Your dwelling coverage limit should reflect the full replacement cost of rebuilding the home, not the market value.
Covers your personal belongings — furniture, electronics, clothing, appliances — against loss from insured perils. Standard contents limits are often insufficient for high-value collections, jewellery, or electronics. Additional scheduled coverage is available.
Protects you if someone is injured on your Markham property and you are found legally responsible. Standard coverage is typically $1M–$2M. Markham homeowners with pools, trampolines, or high visitor traffic should consider higher liability limits.
Covers temporary accommodation and additional living costs if your Markham home becomes uninhabitable due to an insured loss — such as a fire or major water damage — while repairs are completed.
What Home Insurance Covers — and What It Does Not
- Overland water / flood damage (requires separate endorsement)
- Sewer backup (requires separate endorsement)
- Earthquake damage (requires separate endorsement)
- Gradual damage — slow leaks, mold from ongoing moisture
- Normal wear and tear or maintenance issues
- Rental activity — standard policy excludes income suites without endorsement
- Home-based business equipment and liability
- Fire and smoke damage
- Lightning strikes
- Windstorm and hail damage
- Theft and vandalism
- Accidental water damage — burst pipes, appliance leaks
- Falling objects — trees, ice
- Liability for injuries on your property
Overland flooding and sewer backup are among the most common and costly claims in the GTA — and they are excluded from standard Ontario home insurance policies. Kaizen Real Estate Team strongly recommends that every Markham buyer ensure their policy includes both overland water and sewer backup endorsements before closing day. The additional premium is typically modest relative to the potential claim.
How Much Do Markham Homeowners Pay for Home Insurance?
Home insurance premiums in Markham vary based on a combination of property-specific factors, coverage selections, and the individual insurer's risk assessment. The figures below represent typical annual premium ranges for Markham properties in 2025 — individual quotes will vary.
What Factors Affect Your Markham Home Insurance Premium
| Factor | How It Affects Your Markham Premium |
|---|---|
| Replacement cost of the home | Higher rebuild value = higher dwelling coverage limit = higher premium |
| Age and condition of roof | Roofs over 20 years old significantly increase premiums; some insurers decline or surcharge |
| Heating system type | Oil heating, older electrical panels (knob-and-tube, aluminum wiring) increase premiums considerably |
| Claims history | Prior claims — yours or the property's — increase premiums; multiple claims can result in non-renewal |
| Proximity to fire station | Closer proximity to a Markham fire station can reduce premiums |
| Security features | Monitored alarm systems, deadbolts, and smart home security can reduce premiums |
| Deductible selected | Higher deductible = lower annual premium; common deductibles are $1,000–$2,500 |
| Bundling with auto insurance | Multi-policy discounts typically save 10–15% on both home and auto premiums |
What Markham Buyers Must Have in Place Before Closing Day
Your mortgage lender will require a Certificate of Insurance or binder letter from your insurer before releasing funds on closing day. This document confirms your coverage is in force as of the closing date. Failing to arrange insurance before closing day can delay or prevent your purchase from completing — Kaizen Real Estate Team reminds every Markham buyer of this requirement well in advance of their closing date.
Some Markham properties — particularly older homes with aging electrical panels, galvanized plumbing, oil heating, or flat roofs — can be difficult or expensive to insure. Kaizen Real Estate Team advises buyers to obtain an insurance quote as soon as an offer is accepted, so that any coverage issues can be identified and addressed during the conditional period — not on closing day.
- Obtain your insurance quote immediately — as soon as your offer is accepted, contact insurers or a broker for a quote on your Markham property
- Confirm your lender's minimum requirements — your mortgage lender will specify minimum dwelling coverage requirements; your insurer must meet these
- Request a binder or Certificate of Insurance — have your insurer issue the certificate effective on your closing date and provide it to your lawyer
- Confirm overland water and sewer backup are included — do not assume they are standard; add these endorsements at the time of purchase
- Disclose all relevant property features — basement suite, home-based business, trampoline, pool — to avoid claim denial
