Home Insurance Ontario 2026: Coverage and Average Costs (GTA, Ottawa)
Renting a Toronto condo or buying a house in Ottawa: whichever the format, an Ontario home insurance policy uses its own vocabulary — Form 3, Form 4, sewer backup rider — and premiums that climb every year. In 2026, plan on $1,250 to $2,400 per year for comprehensive coverage. Here’s how to decode what you’re paying for.
Form 3, Form 4, Form 6: Ontario’s vocabulary
Unlike Quebec, where forms follow the BAC nomenclature, Ontario uses the American Homeowner Form (HO) system as adapted by IBC:
- Form 3 (HO-3) — homeowner policy: open perils on the dwelling, named perils on contents. Standard for single-family homes.
- Form 4 (HO-4) — tenant policy. Contents, liability, additional living expenses.
- Form 6 (HO-6) — condo owner policy. Improvements, contents, liability, unit-owner gap over the master policy.
- Form 5 (HO-5) — enhanced comprehensive — open perils on BOTH dwelling and contents. The broadest, roughly 20 % more than Form 3.
2026 average costs: GTA, Ottawa, regions
Ontario premiums rose 7.4 % in 2025 per IBC. Rough ranges for a $400K–$800K home:
- Toronto (Old Toronto, York): $2,100–$2,400/yr
- Mississauga, Brampton: $1,900–$2,200/yr
- Ottawa: $1,400–$1,700/yr
- Kingston, London: $1,250–$1,500/yr
- Thunder Bay, Sudbury: $1,100–$1,400/yr
Key rating factors: aging sewer infrastructure (Toronto, Hamilton), flood zones mapped by Conservation Ontario, distance to fire hydrant, and fire protection grade. A broker canvasses 8 to 15 insurers and often finds $300–$500 gaps on identical risks.
Sewer backup and overland water: don’t skip these
Two optional but nearly essential add-ons in Ontario:
- Sewer backup — $40 to $120/year. Toronto has seen two major floods in the past decade; without this endorsement, a flooded basement isn’t covered.
- Overland water — $60 to $200/year. Added by Aviva/Intact/Wawanesa since 2015. Essential near the Don, Humber, Rideau, and Grand rivers.
- Groundwater — $40 to $80/year. Rarely offered; ask explicitly.
Frequently asked questions
Is my Quebec policy valid in Ontario?
No. It must be issued by an Ontario-licensed insurer. An interprovincial move requires cancelling the old policy and taking out a new one.
Do I need coverage if my condo is already insured by the corporation?
Yes. The corporation’s master policy covers the structure and common areas, but not your improvements (floors, counters), your contents, or your personal liability.
Should my insured value match the purchase price?
No — it should match the replacement cost (materials + labour), often 60 to 80 % of the sale price in urban areas.
Can I ask for “replacement cost” on contents?
Yes. On an old stolen TV, the insurer pays for a new equivalent instead of the depreciated value. Ask at underwriting.
