You have three commercial property insurance quotes on your desk. One is the cheapest. One has the most pages. One came from the broker who returned your call fastest. None of that tells you which policy is actually the best.
The best commercial property insurance policy in Canada is the one that pays out fully when you have a loss and does not surprise you with gaps, penalties, or exclusions you did not know about. Price matters, but it is the last thing you should compare, not the first.
Here are 10 things to evaluate before you buy or renew.

1. Broad Form vs. Named Perils
This is the foundation of your policy. It determines what triggers a payout.
Named perils policies only cover the specific risks listed in the policy (fire, lightning, explosion, theft, etc.). If the cause of your loss is not on the list, there is no coverage.
Broad form (sometimes called all-risk) policies cover all causes of loss except those specifically excluded. The exclusion list is shorter than the coverage list. You are protected against more scenarios.
Broad form is the standard for commercial property in Canada. If you are being quoted a named perils policy, ask why. In most cases, broad form is worth the premium difference.
What to check: Look at the declarations page and the causes of loss form attached to your policy. Confirm it says “broad form” or “all risk,” not “basic” or “named perils.”
2. Extension Package Depth
A base broad form policy covers the fundamentals. But the real differentiation between good and mediocre coverage is in the extension package.
Most Canadian carriers offer bundled extension packages with 40 to 60+ additional coverages. These packages come in tiered levels with increasing limits. A typical structure looks like this:
| Level | Blanket Limit (On-Premises) | Blanket Limit (Off-Premises) |
| 1 | $250,000 | $50,000 |
| 2 | $500,000 | $100,000 |
| 3 | $750,000 | $250,000 |
| 4 | $1,000,000 | $250,000 |
The top-tier packages also include additional perils not covered at lower levels, such as seepage, leakage, settling, and contamination.
What to check: How many extensions are included? What are the blanket limits at each tier? Are there coverages only available at the highest tier that your business needs? The difference in premium between Level 1 and Level 3 is often modest relative to the coverage gap.
3. Business Interruption Indemnity Period
Business interruption (BI) insurance covers your lost income and fixed expenses while your property is being repaired after a covered loss. The indemnity period is how long that coverage lasts.
Most BI policies run 12 months from the date of loss. For a minor claim, that is plenty. For a total loss on a commercial building in Canada, 12 months may not be enough. Permit delays, contractor availability, material supply issues, and municipal inspections can stretch a rebuild to 18 months or longer.
What to check: What is your BI indemnity period? Is it 6 months, 12 months, or longer? Does it match a realistic rebuild timeline for your property type and location? Can you extend it?
4. Coinsurance Clause and Waiver Options
The coinsurance clause requires you to insure your property to a certain percentage of its replacement cost (usually 80% or 90%). Fall short and the carrier reduces your claim payout proportionally.
This is one of the most misunderstood provisions in commercial property insurance. A 2025 industry report found that 96% of organizations lack a formal process for updating property values each year. That means most businesses are at risk of a coinsurance penalty without knowing it.
What to check:
- What is your coinsurance percentage?
- Are you meeting it based on current replacement costs?
- Does your extension package include a coinsurance waiver for smaller losses?
- Can you get an Agreed Value endorsement that eliminates the coinsurance clause entirely?
For a full breakdown of how coinsurance penalties work, see our guide to commercial property insurance gaps.
5. Deductible Structure
Most commercial property policies use a flat dollar deductible (e.g., $1,000, $2,500, $5,000, $10,000). Straightforward. You pay the deductible, the insurer pays the rest up to your limit.
But watch for percentage deductibles on specific perils. Earthquake coverage in BC commonly uses percentage deductibles of 5% to 15% of the insured value. On a $2,000,000 building, a 10% earthquake deductible means $200,000 out of pocket before coverage kicks in. Hail deductibles in Alberta operate similarly.
Some extension packages waive your deductible for losses above a certain threshold (typically $250,000). That is a meaningful benefit on larger claims.
What to check: Is your deductible flat or percentage-based? Are there separate deductibles for specific perils (earthquake, wind, hail, flood)? Does your extension package include a deductible waiver for large losses?
6. By-Laws and Green Upgrade Coverage
After a major loss, you rebuild. But building codes have changed since the original construction. The city requires you to meet current standards: updated electrical, plumbing, fire suppression, accessibility, and energy codes.
Standard property insurance pays to restore what you had. By-laws coverage pays the additional cost to meet current code. Green upgrade coverage goes further and pays to replace damaged components with energy-efficient alternatives.
On older buildings, the cost to rebuild to code can exceed the original replacement cost by 20% to 40%. Without by-laws coverage, you absorb that difference.
What to check: Is by-laws coverage included in your policy or extension package? What is the limit? Is there a green upgrade provision? How old is your building, and how much has the code changed since it was built?
7. Newly Acquired Location and Contents Coverage
Businesses grow. You open a second location, lease a warehouse, or buy a major piece of equipment mid-term. Your policy may automatically extend coverage to new assets, but only for a limited window and up to a capped amount.
What to check: Does your policy include automatic coverage for newly acquired buildings and contents? How long is the coverage window (30 days, 60 days, 90 days)? What is the dollar cap? Do you need to report new assets to your broker within that window to maintain coverage?
8. Carrier Financial Strength
Your insurer needs to be able to pay your claim. That sounds obvious, but not all carriers are equally capitalized.
AM Best is the primary rating agency for insurance company financial strength. Look for carriers rated A- (Excellent) or higher. You can check any carrier’s rating at ambest.com.
In Canada, the Property and Casualty Insurance Compensation Corporation (PACICC) protects policyholders if a member insurer becomes insolvent, but coverage limits apply. You are better off with a financially strong carrier in the first place.
What to check: What is your carrier’s AM Best rating? Is the carrier a PACICC member? Has the carrier been downgraded recently?
9. Claims Service Reputation
A policy is only as good as the claims experience behind it. When you have a $500,000 fire loss, you need a carrier with experienced commercial adjusters who handle your claim efficiently and fairly.
What to look for:
- Dedicated commercial claims team (not a shared personal/commercial call center)
- Named adjuster assigned to your file from start to finish
- Proactive communication with status updates to you and your broker
- Access to preferred contractors and emergency response vendors
- Mobile response capability for catastrophic events (wildfires, floods)
Your broker should be able to tell you about their claims experience with each carrier. Ask directly: “What has your claims experience been with this carrier on commercial property losses?”
10. Broker Expertise and Market Access
The broker you work with determines what carriers and products you see. A broker with access to three carriers gives you three options. A broker with access to 15 carriers, plus specialty and surplus markets, gives you a much wider range of coverage and pricing.
What to look for in a broker:
- Licensed in your province
- Access to multiple national, regional, and specialty carriers
- Experience with your industry and property type
- Willingness to explain coverage in plain language
- Annual policy review as standard practice (not just renewal paperwork)
- Advocacy at claims time
Ai Insurance Organization works with national carriers, regional insurers, and specialty markets across Canada (except Quebec). Our brokers handle everything from simple office property to complex multi-location accounts.
Red Flags in a Commercial Property Quote
Not every quote is worth considering. Here are warning signs:
- No extension package included. A bare broad form policy without extensions leaves significant gaps.
- ACV valuation without explanation. If the quote is on actual cash value and nobody explained why, ask. RC should be the default.
- Low building limit with no appraisal. If the building limit looks low and nobody asked for a replacement cost estimate, you are likely underinsured.
- No business interruption coverage. If BI is not included or offered, you are missing a major piece.
- Percentage deductibles buried in the fine print. Especially for earthquake, hail, or wind. Read the deductible schedule carefully.
- Carrier you have never heard of with no AM Best rating. Financial strength matters when it is time to collect.
How to Compare Two Quotes Side by Side
Use this template when evaluating competing quotes:
| Criteria | Quote A | Quote B |
| Carrier name and AM Best rating | ||
| Coverage form (broad form / named perils) | ||
| Building limit | ||
| Contents limit | ||
| Valuation method (RC / ACV) | ||
| Coinsurance percentage | ||
| Extension package (level and # of coverages) | ||
| Business interruption included? Indemnity period? | ||
| Equipment breakdown included? | ||
| Flood / earthquake / sewer backup endorsements | ||
| By-laws coverage limit | ||
| Newly acquired property (window and cap) | ||
| Deductible (flat and any percentage deductibles) | ||
| Deductible waiver threshold | ||
| Annual premium |
Compare coverage first, then price. The cheapest quote with fewer extensions, shorter BI periods, or ACV valuation is not actually cheaper when you file a claim.
Frequently Asked Questions
What is the best commercial property insurance in Canada?
There is no single “best” carrier. The best policy is the one that matches your specific risk profile with appropriate limits, broad form coverage, a strong extension package, adequate business interruption, and a financially stable carrier. A broker who quotes multiple markets will find the right fit for your situation.
Should I choose the cheapest commercial property insurance quote?
Not automatically. A lower premium often comes with narrower coverage, lower limits, ACV valuation, or missing extensions. Compare coverage side by side before comparing price. The cheapest quote that leaves you underinsured is the most expensive policy you can buy.
How many extension coverages should a good policy include?
Most competitive carrier packages in Canada include 40 to 60+ extensions at the mid-to-upper tiers. The number matters less than the specific coverages included. Make sure your package covers business interruption, debris removal, by-laws, newly acquired property, and off-premises service interruption at minimum.
What is an AM Best rating and why does it matter?
AM Best rates the financial strength of insurance companies. A rating of A- (Excellent) or higher means the carrier has strong ability to pay claims. You can check any carrier’s rating at ambest.com. Working with a financially strong carrier protects you if you need to collect on a large loss.
How often should I review my commercial property policy?
At minimum, every year at renewal. You should also review mid-term after renovations, new equipment purchases, acquisitions, or changes in operations. Property values, building codes, and your business operations all change over time, and your policy needs to keep up.
