Business Interruption Insurance in Ontario, Canada

Commercial Insurance | Boardwalk Insurance — A Division of Oracle RMS

Business Interruption insurance — also called Business Income insurance — covers the revenue your business loses and the fixed expenses it continues to incur when a covered physical damage event forces a temporary closure or operational reduction. It is the coverage that bridges the gap between the moment a fire, flood, or major equipment failure occurs and the moment your business returns to full normal operations. Without it, commercial property insurance rebuilds your building and replaces your equipment, but leaves your business to absorb the full revenue loss during the months of reconstruction. Boardwalk Insurance helps Ontario businesses structure Business Interruption coverage that matches their actual revenue and fixed cost profile. Serving all provinces except Quebec.

What Is Business Interruption Insurance?

Business Interruption (BI) insurance compensates a business for the financial losses it suffers when its operations are interrupted by a covered peril — typically fire, water damage, storm damage, or equipment breakdown — that damages the physical premises or equipment the business depends on to generate revenue. It does not cover the physical damage itself (that is commercial property insurance's role) — it covers the downstream financial consequence of that damage: the revenue that stops coming in while the business cannot operate.

The practical importance of Business Interruption insurance is often understood best through what happens without it. A manufacturing facility that suffers a major fire faces two simultaneous crises: rebuilding the physical plant (covered by commercial property insurance) and surviving financially for the 6 to 18 months it takes to rebuild (covered by Business Interruption insurance). A restaurant that floods and must close for four months while rebuilding faces a property loss (covered) and a four-month revenue loss with ongoing lease, loan, and payroll obligations (covered only if Business Interruption is in place). Without BI coverage, many businesses that survive the physical loss do not survive the financial interruption that follows it.

The Triggering Requirement: A Covered Physical Loss

Business Interruption insurance responds only when the interruption is caused by a covered physical loss under the associated commercial property policy. The trigger is physical damage to insured property — not market conditions, supply chain disruptions, regulatory closures, or loss of a key customer. This linkage to a physical loss trigger is an important limitation to understand: Business Interruption coverage does not respond to every possible reason a business might lose revenue.

What Does Business Interruption Insurance Cover?

Lost Net Income

The primary coverage under a Business Interruption policy is the net income (profit) the business would have earned during the interruption period — the period from the date of the covered loss through the date the business returns to normal operations, up to the maximum indemnity period specified in the policy. Net income is typically calculated by reference to historical financial statements, adjusted for any known changes in the business.

Continuing Fixed Expenses

During a closure or partial closure, many fixed expenses continue regardless of whether revenue is being generated. Business Interruption insurance covers these continuing fixed expenses, which typically include:

Rent or mortgage payments on the business premises
Loan repayments (principal and interest on equipment and term loans)
Utility costs at the closed or partially-closed location
Insurance premiums
Property taxes
Certain employee wages for key staff retained during the closure period

Extra Expenses

Most Business Interruption policies also cover Extra Expenses — the additional costs incurred to minimize the interruption period or to continue partial operations during the recovery. Extra expenses might include:

Temporary rental of replacement equipment
Leasing a temporary alternative location
Expediting shipment of replacement materials or equipment
Additional overtime costs to accelerate reconstruction
Costs of relocating operations temporarily to another facility

Extra expenses coverage recognizes that a business will often incur costs beyond normal operating expenses specifically to reduce the length of the interruption — and that those costs benefit the insurer by reducing the total Business Interruption claim.

Key Supplier and Dependent Properties

Business Interruption can be extended to cover losses that arise when a key supplier, customer, or business the insured depends on suffers a covered loss that indirectly interrupts the insured's operations:

Contingent Business Interruption (CBI): Covers revenue loss caused by a physical damage event at a key supplier's or customer's premises that disrupts the supply chain or customer relationship
Leader Location Coverage: Covers revenue loss to a business (such as a retail store in a mall) when a nearby anchor or traffic-generating business suffers a covered loss and reduces foot traffic
Utility Services Interruption: Covers revenue loss caused by a covered damage event at a utility provider that results in loss of power, gas, water, or communications to the insured business

Key Business Interruption Policy Terms

Indemnity Period

The maximum period for which Business Interruption claims will be paid — the time allowed to restore the business to its pre-loss condition. Standard indemnity periods range from 12 to 36 months. Businesses with complex equipment, specialized facilities, or long permitting and reconstruction timelines should carry an indemnity period that genuinely reflects their worst-case reconstruction scenario. An indemnity period that expires before the business is back to full operations leaves a coverage gap for the remaining interruption period.

Waiting Period (Deductible)

Most Business Interruption policies include a time-based deductible — a waiting period (commonly 24 to 72 hours) following the date of loss before coverage begins. The insured absorbs the business income loss during this initial period. The length of the waiting period affects the premium: a longer waiting period reduces premium but increases the business's retained loss exposure.

Coinsurance

Like commercial property policies, Business Interruption policies often contain a coinsurance provision. The insured is required to carry Business Interruption coverage equal to at least a specified percentage (commonly 80% or 100%) of the business's actual annual revenue or business income. If the carried BI limit is less than the required coinsurance amount, the insured bears a proportionate share of any claim — which can substantially reduce the claim recovery. Accurate calculation of the required Business Interruption limit is essential to avoid coinsurance penalties.

The Most Common Business Interruption Mistake: Underinsurance

The single most common Business Interruption claim problem in Canada is underinsurance — the insured carrying a Business Interruption limit that is substantially lower than their actual annual revenue and fixed cost exposure. This happens for several reasons:

The BI limit was set years ago and never updated as revenue grew
The BI limit was estimated rather than calculated from actual financial statements
The insured set the BI limit equal to one or two months of revenue rather than the full indemnity period's revenue at risk
The coinsurance requirement was not understood, and the limit was set too low relative to the coinsurance formula

The consequence of underinsurance is a coinsurance penalty at the time of claim — the insurer pays only a proportionate share of the loss, calculated as (carried limit ÷ required limit) × claim amount. A business with $2 million in annual revenue that carries a $500,000 Business Interruption limit subject to 80% coinsurance has a required limit of $1.6 million. If a claim arises for $600,000 in lost income, the insurer pays only ($500,000 ÷ $1,600,000) × $600,000 = $187,500 — leaving the insured to absorb $412,500 of the loss out of pocket. → See Boardwalk's Coinsurance Penalty Simulator to model how coinsurance affects a claim.

Frequently Asked Questions About Business Interruption Insurance

What does Business Interruption insurance cover?

Business Interruption insurance covers the net income a business loses and the fixed expenses it continues to incur when a covered physical damage event — typically fire, water damage, storm, or equipment breakdown — forces a temporary closure or reduction in operations. It does not cover the physical damage itself (commercial property insurance covers that). It covers the downstream financial consequence: lost revenue and ongoing fixed costs during the reconstruction or recovery period.

Does Business Interruption insurance cover COVID-19 closures or pandemics?

Standard Business Interruption policies in Canada require a covered physical loss to the insured property as the trigger for coverage. Government-mandated closures due to a pandemic — without any physical damage to the insured premises — do not trigger coverage under standard BI policies, as was confirmed in litigation arising from COVID-19 closures across Canada. Some specialty BI policies and endorsements may cover specific categories of non-damage interruption, but standard commercial BI policies do not cover pandemic-related closures.

How much Business Interruption insurance do I need?

The Business Interruption limit should be set at the amount of gross revenue (or gross profit, depending on the policy form) the business could lose during the full indemnity period in a worst-case scenario. For a business with $2 million in annual revenue and a 24-month indemnity period, the potential BI exposure is up to $4 million in a total-loss scenario where the business cannot operate for 24 months. Most businesses do not need to insure for the absolute worst case, but the BI limit should be set based on an honest assessment of the realistic maximum interruption period and the revenue and fixed costs at risk during that period.

Is Business Interruption insurance separate from Commercial Property?

Business Interruption is typically purchased as an extension of a Commercial Property policy — it is not usually a standalone policy, because it requires a covered physical loss to trigger coverage. When a business purchases Commercial Property insurance, Business Interruption coverage is typically added as an endorsement or as a separate insuring agreement within the same policy. The BI coverage limit, indemnity period, and waiting period are set separately from the property coverage limits.

What is an indemnity period and how long should it be?

The indemnity period is the maximum length of time for which Business Interruption claims will be paid — the time allowed to restore the business to full normal operations. Standard indemnity periods are 12 or 24 months. Businesses with complex operations, specialized equipment, or facilities subject to lengthy permitting processes should carry a 24 or 36-month indemnity period. A restaurant in a leased space might rebuild in 6 months; a manufacturing facility with custom equipment and a facility requiring permitting might take 18 to 24 months. The indemnity period should reflect the genuine worst-case reconstruction timeline, not an optimistic estimate.
