20 Factors that Affect Your Home Insurance Premiums in 2026 

If you've noticed your home insurance premium climbing year after year, you're not alone. Ontario homeowners are experiencing significant rate increases driven by climate change, inflation, and rising claim costs. Understanding what influences your premium is the first step toward managing these costs effectively. 

In this article, you will learn: 

  • What a home insurance premium is and how it's calculated 
  • Property-related factors that impact your premium, including location, rebuild costs, home age, and construction type. 
  • Coverage and policy-related factors like coverage amounts, endorsements, deductibles, and bundling options 
  • Personal profile and history factors such as claims history, credit score, and occupancy type 
  • Why premiums are increasing across Ontario in 2026 
  • Practical steps you can take to reduce your premium 

What Is a Home Insurance Premium? 

Your home insurance premium is the amount you pay for coverage, typically on a monthly or annual basis. Think of it as the price of financial protection for your home and belongings. 

Premiums reflect two key components: your individual risk profile and the insurer's cost to cover potential claims. A homeowner in a flood-prone area with an older home will generally pay more than someone with a newly built home in a low-risk neighbourhood. Insurers calculate these rates by analyzing dozens of risk factors specific to your property and personal history. 

How Are Home Insurance Premiums Calculated in 2026? 

Home insurance premiums in 2026 are calculated using sophisticated risk assessment models that have evolved significantly in recent years. Insurers now place greater emphasis on climate-related risks, rebuild costs, and loss patterns that have emerged over the past few years. 

Several major trends are driving premium calculations in Ontario: 

  • Rising rebuild costs: Labour shortages and materials inflation have increased construction costs by double digits, meaning it costs significantly more to rebuild your home today than just a few years ago. 
  • Climate change and increased weather events: More frequent severe storms, flooding, and extreme weather have led to higher claim volumes across the province. 
  • Labour and materials inflation: Supply chain disruptions and inflation have pushed up the cost of everything from lumber to roofing materials. 
  • Higher water damage claims nationwide: Water damage now accounts for the majority of home insurance claims in Canada, with basement flooding and burst pipes becoming increasingly common. 
  • Rising reinsurance costs: Insurers themselves pay more for their own insurance coverage (reinsurance), and these costs are passed along to policyholders. 

Home insurance premiums are determined by three main categories of factors: 

  • Property-related factors: Your home's location, age, size, construction type, and physical features 
  • Coverage and policy-related factors: The amount and type of coverage you choose, your deductible, and optional endorsements 
  • Personal profile and history factors: Your claims history, insurance continuity, credit score, and how you use your home 

20 Key Factors That Affect Home Insurance Premiums 

1. Location & Postal Code Risk 

Your postal code determines premium based on crime rates, flood zones, wildfire risk, and weather patterns. Urban areas face theft risk; rural properties may lack nearby fire services. In 2026, insurers focus heavily on flood mapping and climate severity. 

2. Rebuild / Replacement Cost (Not Market Value) 

Premiums reflect rebuilding costs like materials, labour, and code compliance, not market value. Rising construction costs from inflation and supply chain issues have increased replacement values and premiums, even when market values haven't changed proportionally. 

3. Age of Home & Condition of Major Systems 

Older homes cost more due to aging electrical, plumbing, heating, hot water tank, and roofing systems. Systems over 25-30 years old may trigger premium increases or coverage restrictions until upgraded, as they're more prone to failure. 

4. Construction Type & Materials 

Building materials affect damage resistance. Brick and stone lower premiums due to fire resistance. Wood-frame homes and asphalt shingles cost more than metal or tile roofing, which better withstand severe weather. 

5. Square Footage & Home Size 

Larger homes cost more to insure. A 3,000-square-foot home has higher premiums than 1,500 square feet. Calculations include all finished above-grade living space that would require reconstruction after a loss. 

6. Finished Basement or Valuable Renovations 

Finished basements with bedrooms, bathrooms, or offices increase replacement costs and premiums. Major renovations like custom kitchens or additions should be reported to ensure adequate coverage, which increases premiums accordingly. 

7. Pools, Hot Tubs, Trampolines & Outdoor Structures 

Recreational features increase liability and replacement costs. Pools and hot tubs present drowning risks; trampolines bring injury concerns. Detached garages, sheds, and decks add insured value, raising premiums. 

8. Proximity to Fire Hall & Fire Hydrants 

Distance from fire services affects premiums, especially rurally. Homes near fire stations and hydrants benefit from faster response times. Rural properties farther from municipal services face higher premiums. 

9. Home Security, Fire Prevention & Water Mitigation Devices 

Monitored alarms and smart technology reduce premiums. Insurers offer discounts for water leak detectors, smart smoke detectors, automatic shut-off valves, and sump pump monitors that prevent claims.  

10. Home Updates or Renovations 

Recent upgrades to electrical, roofing, plumbing, hot water tank, or heating systems may lower premiums by reducing risk. Notify your insurer about renovations to ensure proper coverage—some upgrades might temporarily increase premiums until completion. 

11. Amount of Coverage You Choose 

Higher coverage equals higher premiums. Insuring for $500,000 versus $400,000 costs more due to larger potential payouts. However, underinsuring to save money risks inadequate funds for rebuilding after a total loss. 

12. Optional Endorsements (Sewer Backup, Overland Water, Earthquake) 

Standard policies don't cover everything. Sewer backup and overland water protection are increasingly essential in Ontario. Each endorsement increases premiums but provides critical protection against rising water-related claims in 2026. 

13. Deductible Amount 

Higher deductibles reduce premiums significantly. Choosing $2,500 versus $1,000 lowers annual costs but requires covering that amount out-of-pocket. Balance immediate savings against potential future expenses you can afford. 

14. Bundling with Auto or Other Policies 

Multi-policy discounts typically save 10-25% when bundling home and auto insurance. This simplifies management with one provider and can streamline claims processing for incidents affecting both property types. 

15. Mortgage-Free Discounts 

Some insurers offer discounts for mortgage-free homeowners, though not universally available. The reasoning: outright ownership demonstrates financial stability and suggests better property maintenance, reducing risk. 

Personal Profile & History Factors 

16. Claims History (5-Year Record) 

Your five-year claims history strongly predicts future risk. Multiple claims, especially water damage or liability, increase premiums substantially. Claims-free history qualifies for discounts, encouraging out-of-pocket payment for smaller repairs. 

17. Continuous Insurance History 

Maintaining coverage without gaps demonstrates responsibility. Lapses or cancellations result in higher premiums or limited options. Insurers reward continuous coverage with loyalty discounts, viewing it as lower-risk behavior. 

18. Credit Score (Where Allowed) 

Some Ontario insurers use credit information when determining premiums, though regulated. Strong credit scores indicate financial responsibility and correlate with lower claim frequencies. Improved scores may positively impact rates. 

19. Occupancy Type 

Owner-occupied primary residences have lowest rates due to better maintenance and quick issue resolution. Rental properties and seasonal cottages cost more due to increased wear, less oversight, and risks like frozen pipes. 

20. Home-Based Business Activity 

Running a business from home affects coverage and premiums. Standard policies provide limited business coverage. Consulting, daycare, or other home operations may require additional endorsements or separate home-based business policies, impacting premiums based on complexity. 

Why Are Home Insurance Premiums Increasing in 2026? 

Ontario homeowners are experiencing home insurance rate increases. Understanding the broader industry factors helps explain why your premium keeps rising even if you haven't made claims. 

  • Climate change is the single biggest driver of increasing premiums. Severe weather events like windstorms, hail, ice storms, and flooding now occur with greater frequency, leading to billion-dollar insurance losses across Canada and forcing insurers to adjust rates. 
  • Extreme weather loss data from the past five years shows dramatic increases in claim severity and frequency. Ontario's catastrophic weather events have resulted in widespread damage, affecting the entire insurance pool through premium increases. 
  • Supply chain disruptions and inflation have pushed construction costs 20-30% higher than three years ago. Lumber, copper, roofing materials, and labour shortages in skilled trades have increased dramatically, directly impacting replacement cost calculations and premiums. 
  • Higher cost of claims extends beyond the weather. Water damage claims including burst pipes, sewer backups, and basement flooding have become increasingly common and expensive. The average water damage claim now costs insurers significantly more due to extensive restoration work and increased contractor costs. 
  • Increasing frequency of water damage deserves special attention. Water-related claims now represent the majority of home insurance claims in Ontario. Aging infrastructure, heavier rainfall, and more finished basements make water damage the most common and costly peril. 
  • Rising reinsurance costs create a ripple effect. Reinsurance (insurance that insurance companies purchase against catastrophic losses) has become substantially more expensive due to global climate events, ultimately reflected in homeowner premiums. 

How to Reduce Your Home Insurance Premium 

While you can't control market trends or weather patterns, there are several concrete steps you can take to potentially lower your home insurance premium: 

  • Install security and water sensors: Water leak detectors, smart smoke alarms, and monitored security systems help prevent claims. Many insurers offer discounts for these devices. Install water sensors near your water heater, washing machine, and basement. 
  • Update your roof, plumbing, and electrical systems: Major system upgrades reduce risk and often qualify you for discounts. A new roof, updated electrical panel, new hot water tank, or updated modern plumbing can result in ongoing premium savings plus increased home value. 
  • Increase your deductible: Raising your deductible from $1,000 to $2,500 or $5,000 can substantially reduce your annual premium. Ensure you're comfortable paying that amount out-of-pocket if you need to make a claim. 
  • Bundle home and auto insurance: Bundling your policies is often the easiest way to save up to 25% on premiums. Even if you switch providers to bundle, the savings typically outweigh minor differences in individual policy costs. [Link opportunity: Morison's bundling page] 
  • Maintain a claims-free history: Think strategically about filing claims for smaller amounts. If the claim value is only slightly higher than your deductible, paying out-of-pocket may preserve your claims-free status and avoid premium increases. 
  • Ask your broker about available discounts: Insurance companies offer numerous discounts many homeowners don't know about. Your broker can ensure you're receiving all applicable home insurance discounts. 
  • Avoid small claims where possible: Insurance protects against significant financial losses, not routine maintenance. Consider whether filing claims for minor damage is worth potential premium increases. Building an emergency fund helps avoid small claims that cost more long-term. 

Home Insurance Premiums FAQs 

Why is my homeowners insurance going up every year? 

Annual premium increases reflect rising costs across the insurance industry. Rebuild costs have increased dramatically due to inflation and supply chain issues, while climate change has led to more frequent and severe weather claims. Even without personal claims, your premium increases because insurers must account for these industry-wide cost pressures and maintain financial stability to pay claims. 

What can I do to lower my home insurance premium? 

Focus on controllable factors: increase your deductible, bundle with auto insurance, install protective devices like water sensors and security systems, maintain a claims-free record, and ask your broker about available discounts. Upgrading major systems like your roof, electrical, and plumbing can also reduce risk and potentially lower premiums. 

Does making a claim always increase premiums? 

Not necessarily, but it depends on the type and frequency of claims. A single claim for something beyond your control (like storm damage) may not significantly impact your rate, especially if you have a long claims-free history. However, multiple claims within a few years or claims for preventable issues (like lack of maintenance) will likely result in premium increases or coverage restrictions. 

Why did my premium increase even though I didn't make a claim? 

Your premium reflects both your individual risk and broader insurance pool costs. Even with no personal claims, your rate can increase due to industry-wide factors: higher rebuild costs, increased claims in your area or postal code, severe weather affecting the entire province, or rising reinsurance costs. Insurers adjust rates for all policyholders to remain financially viable. 

What affects home insurance rates the most in Ontario? 

Location is consistently one of the biggest factors, particularly flood risk and proximity to fire services. Your home's age and condition, especially of major systems, also significantly impact rates. In 2026, climate-related risks and water damage exposure are weighing more heavily in rate calculations than ever before. Replacement cost increases due to inflation are another major driver of higher premiums across the province.
