Most businesses plan for property damage. Few plan for the months after, when revenue stops but rent, payroll, loan payments, and supplier obligations keep moving.
Business interruption insurance exists for that gap. In Ontario, it is often the difference between reopening and quietly closing.
Business interruption insurance
Who this applies to
This is for Ontario and Canada wide businesses where downtime creates immediate financial pressure, including:
Retail and restaurants
Manufacturing and warehousing
Contractors and service businesses
Medical and professional offices
Property owners with rental income
Logistics and trucking operations
Multi location operators and franchises
If you would struggle to operate for even two weeks with zero revenue, business interruption insurance is worth serious attention.
What business interruption insurance is
Business interruption insurance replaces income and helps pay ongoing expenses when your business is forced to stop or slow down because of a covered loss.
It is usually attached to a commercial property policy, but it can also appear in other forms, like cyber business interruption under a cyber policy.
Key definitions that matter
Business interruption: Coverage for lost income and continuing expenses when a covered event forces your operations to stop or slow down.
Extra expense: Coverage that pays for reasonable costs to reduce downtime, like temporary space, expedited shipping, or overtime.
Indemnity period: The time window the policy will pay for, usually capped by a time limit you select.
Waiting period: A time deductible, often expressed in hours, before coverage starts.
Contingent business interruption: Coverage for income loss caused by a covered loss at a key supplier or key customer location.
Civil authority: Coverage that may respond when access is restricted by a government order due to a nearby covered event, subject to policy terms.
What is covered and not covered
Business interruption coverage is practical, but it is not automatic for every shutdown. It is tied to specific triggers and wording.
What it often covers
Covered loss at your premises that forces operations to stop, such as:
• Fire and smoke damage that requires repairs
• Burst pipe or sprinkler discharge that damages the space
• Storm damage where the policy includes the right water and wind coverages
• Equipment damage that is covered and stops production, when equipment breakdown coverage is in place
It can cover:
• Lost gross profit or lost income based on your policy form
• Continuing expenses like rent, loan payments, and key payroll
• Extra expense to speed reopening, like temporary premises, rental equipment, and expediting costs
What it often does not cover
Common reasons claims are denied or limited:
• No covered cause of loss, like a voluntary closure or a purely economic downturn
• Maintenance issues or gradual deterioration
• Utilities failure unless endorsed
• Supplier shutdown unless contingent business interruption is added
• Pandemic related shutdowns under many standard forms
• Understated revenue or margin, leading to an underinsured limit
• An indemnity period that ends before you are actually back to normal output
Common claim scenarios in Ontario
Business interruption losses are rarely neat. They usually include operational ripple effects.
Retail and restaurants
• Fire in the unit or neighbouring unit leads to an order to vacate
• Water loss forces shutdown during remediation
• Equipment failure spoils inventory and stops sales
Contractors and service businesses
• Shop or storage unit damage disrupts scheduling and revenue
• Theft or fire destroys tools and causes weeks of lost productivity
• Office damage delays bidding, invoicing, and project management
Manufacturers and warehouses
• Equipment breakdown stops a line and creates missed shipments
• Fire triggers long lead times for specialized machinery
• Contaminated stock must be destroyed, slowing fulfilment
Property owners and managers
• A loss makes units uninhabitable and rental income stops
• Major repair schedules extend for months
• Tenant displacement creates additional costs and vacancy risk
Cost drivers and underwriting questions brokers actually ask
Insurers price business interruption based on how likely a shutdown is, how long it would take to recover, and how clearly the numbers are supported.
Expect questions like:
• What would actually stop you from operating
• What percentage of revenue depends on the premises
• Your gross profit, fixed costs, and seasonal swings
• Restoration realities, including contractor availability and lead times
• Single points of failure, like one key machine or one supplier
• Whether you have a documented continuity plan
• How quickly you can operate from an alternate location
• For manufacturing, your maximum possible loss scenario and expediting ability
How to size business interruption insurance properly
Most underinsurance comes from two mistakes.
First, using revenue instead of gross profit and continuing expenses.
Second, underestimating recovery time.
A strong approach looks like this.
Step 1: Define your worst credible shutdown
Pick one scenario that is realistic for your business type. Examples:
• Fire in the premises
• Major water loss
• Breakdown of your critical machine
• Loss of refrigeration for a food business
Step 2: Estimate realistic restoration time
Do not guess based on best case. Use what actually happens in Ontario:
• Permits, inspections, and contractor scheduling
• Specialized equipment lead times
• Environmental remediation where needed
• Tenant coordination and landlord responsibilities
Step 3: Build the financial model around cash flow
Good inputs:
• Monthly gross profit
• Continuing expenses you must pay even if you are closed
• Extra expense you would spend to reopen faster
Step 4: Confirm the policy matches the risk
Check:
• Indemnity period is long enough
• Waiting period fits your cash position
• Extra expense is included and meaningful
• Contingent business interruption is added if supplier risk is real
How to reduce premium without reducing protection
You can often improve pricing by lowering severity and improving clarity, not by cutting the coverage that keeps you alive.
Practical moves insurers respect:
• Maintain updated values and financials, including seasonal peaks
• Add water loss controls, shut off procedures, leak detection, and maintenance logs
• Document maintenance and inspections for critical equipment
• Keep a vendor list for emergency response and restoration
• Improve security for theft and vandalism risk
• Build a simple downtime plan, including alternate location options and temporary equipment
• Use extra expense intentionally to shorten the loss period, then size limits accordingly
Mistakes that create coverage gaps
These are the issues that show up when a business interruption claim goes sideways.
• Assuming business interruption applies to any closure
• Buying too short an indemnity period because it looks cheaper
• Forgetting about seasonality and peak inventory periods
• Not adding equipment breakdown, then suffering a shutdown due to internal failure
• Leaving out contingent business interruption when one supplier drives most production
• Not matching the policy to lease responsibilities and landlord timelines
• Underreporting revenue or margins, then failing a coinsurance or values check
Quick checklist for business interruption readiness
• Identify the top two events that would stop operations
• Confirm your policy trigger matches those events
• Verify your gross profit and continuing expense assumptions
• Choose an indemnity period that reflects real rebuild time, not optimistic time
• Add extra expense to support temporary operations
• Add equipment breakdown if one machine can stop the business
• Add contingent business interruption if supplier dependency is real
FAQ
Is business interruption insurance included in every commercial policy?
Not always. Many policies require you to add it, and the wording can differ by insurer.
Does business interruption pay for lost revenue or lost profit?
Most forms are based on gross profit or net income plus continuing expenses. The difference matters. Your broker should explain which form you have.
How long does business interruption insurance pay for?
It pays during the indemnity period you select, subject to policy terms. Many businesses choose a period that is too short.
Do I need extra expense coverage if I already have business interruption?
Yes in many cases. Extra expense helps you reopen faster, which reduces the size of the claim and protects relationships.
Does business interruption cover supply chain issues?
Only if you have contingent business interruption or another applicable extension. It is not automatic.
Does business interruption cover cyber shutdowns?
Only if your cyber policy includes cyber business interruption and the event meets the policy trigger.
How much business interruption insurance do I need in Ontario?
It depends on your gross profit, fixed costs, seasonality, and realistic recovery time. Two similar businesses can need very different limits.
