WSIB Premium Calculations for Fly-In, Fly-Out (FIFO) Camp Workers in Ontario

30 Jun 2026 4 min read No comments Workers’ Compensation (WSIB) Ontario
💡

For FIFO camp workers in Northern Ontario, WSIB insurable earnings are not just base salary. Employers must accurately report travel allowances and the taxable value of room and board up to the annual maximum ceiling, or risk severe audit penalties.

The resource sector is a cornerstone of Ontario’s economy, with large-scale mining and forestry operations heavily reliant on Fly-In, Fly-Out (FIFO) workers. In remote regions north of Sudbury, Thunder Bay, and Timmins, employees routinely live in employer-provided camps for weeks at a time. While the logistics of running a remote camp are complex, ensuring compliance with the Workplace Safety and Insurance Board (WSIB) can be even more daunting for payroll and HR departments.

A common and costly mistake employers make is miscalculating insurable earnings for FIFO workers. 📋 WSIB premiums are calculated based on the total compensation a worker receives, which extends far beyond their hourly wage. If your company fails to account for travel time compensation or the financial value of the room and board you provide, you are technically under-reporting earnings. This guide clarifies how to calculate WSIB premiums accurately to avoid devastating audits and retroactive fines.

Step-by-Step Process for Calculating FIFO Insurable Earnings

Whether your headquarters is in Toronto or directly at the mine site, the WSIB expects payroll reconciliations to be accurate. Follow these steps to ensure every component of a FIFO worker’s compensation is handled correctly.

Step 1: Calculate Base Wages and Overtime

Start with the most obvious metric: the worker’s gross earnings. 💵 This includes their hourly rate, overtime pay, shift premiums, and production bonuses. For FIFO workers working 12-hour shifts for 14 days straight, overtime makes up a massive portion of their insurable earnings and must be reported in full.

Step 2: Determine Travel Allowances

Travel compensation is heavily scrutinized by the WSIB. If you pay your workers a flat travel allowance or pay them an hourly rate for the time spent flying from their home city to the northern camp, this money is generally considered insurable earnings. However, if you simply purchase the commercial flight ticket directly on behalf of the worker, that specific ticket cost is usually not considered insurable.

Step 3: Assess Room and Board Value

Providing free lodging and meals at a remote camp holds financial value. 🏨 According to WSIB policy, if room and board are considered a taxable benefit by the Canada Revenue Agency (CRA), their value must be added to the worker’s insurable earnings. You must calculate a reasonable daily or monthly dollar value for the camp accommodations and meals and include it in your premium calculations.

Step 4: Apply the Annual Maximum Earnings Ceiling

WSIB sets an annual maximum on insurable earnings per worker, with any earnings exceeding this ceiling exempt from premiums. For 2025, this ceiling was set at $117,000 CAD, and for 2026, it is set at $121,700 CAD. Because FIFO workers often earn well over the limit due to overtime, you must stop paying premiums on an individual once their combined base pay, travel, and room/board hits the maximum for the calendar year.

Step 5: Prepare for Annual Reconciliation

By March 31st of every year, you must submit your annual reconciliation to the WSIB. 📄 Ensure your payroll software properly categorizes non-insurable expenses versus insurable allowances. Retaining a specialized accounting firm or an Ontario labour law firm can help audit your books before the WSIB does.

How Much Does it Cost in Ontario?

Failing to calculate FIFO premiums correctly can result in massive financial liabilities for your company.

Cost CategoryEstimated Financial Impact in CAD
WSIB Premium RateRanges from $1.50 to $5.00+ per $100 of insurable earnings (depends on specific industry risk class).
Annual Maximum CeilingPremiums are capped per worker (set at $117,000 CAD for 2025 and $121,700 CAD for 2026). All earnings above this ceiling are exempt.
Audit PenaltiesRetroactive premiums for up to 3 years, plus interest, and non-compliance fines of $250 to thousands of dollars.
Professional Payroll Review$2,000 to $7,500 CAD annually for an expert legal/accounting review.

How Long Does the Process Take?

Managing WSIB premiums is an ongoing, year-round responsibility. You must calculate and remit premiums either monthly or quarterly, depending on your assigned reporting frequency. If the WSIB decides to audit your FIFO camp operations, the audit process itself can take anywhere from 3 to 6 months of intense scrutiny, requiring you to produce years of travel logs, CRA T4 summaries, and camp expenditure reports.

Frequently Asked Questions (FAQ)

Are independent contractors at the camp covered by WSIB?

It depends. If you hire independent contractors (like specialized drillers), you must ensure they have their own WSIB clearance certificate. If they do not, WSIB will likely reclassify them as your workers, and you will owe retroactive premiums for them.

Is camp food considered an insurable earning?

Generally, if the CRA considers the provided meals a taxable benefit, the WSIB also considers it an insurable earning. There are specific exemptions for remote worksites under CRA rules, so you must confirm your tax status.

What happens if a worker is injured during the flight to camp?

If the employer provides or strictly controls the transportation (like a private charter flight), injuries sustained during that travel are typically covered by WSIB as they are deemed to be in the course of employment.

Do we pay premiums on safety gear allowances?

No. If you provide a direct reimbursement or allowance specifically for required safety equipment (like steel-toed boots or winter parkas), it is generally excluded from insurable earnings.

How can we appeal an unfair WSIB audit regarding room and board?

If an auditor incorrectly assesses your camp expenses, you can file a formal objection to the WSIB Appeals Branch. Many employers hire a law firm to present evidence aligning with CRA remote work exemptions.
