How to Track Mileage for Business in Canada 2026

You know the feeling. It's late February and you're sorting through a shoebox of gas receipts, trying to reconstruct a mileage log that CRA might ask for on a future audit. The problem is common among Canadian small business owners, bookkeepers, and even municipal employees who use personal vehicles for work. If you want to claim vehicle expenses in 2026, you need a proper mileage log. The question is: how to track mileage for Canada business in 2026 efficiently and in a way that holds up to CRA scrutiny.

Why Mileage Tracking Matters in Canada

Business mileage deduction is one of the most common claims on Canadian tax returns, but it is also one of the most reviewed by CRA. If you are self-employed, a partner in a firm, or an employee who must use their own car for work, a contemporaneous mileage log is essential. CRA expects to see the date, destination, purpose, and kilometres driven for each business trip. Without a log, your deduction may be denied or reduced.

The Canada Revenue Agency prescribes an annual rate for automobile allowance and deductible vehicle expenses. For 2026, you should confirm the rate on the CRA website. As a reference, the 2025 rate was $0.70 per kilometre for the first 5,000 business kilometres and $0.64 per kilometre thereafter, for provinces outside the Northwest Territories, Nunavut, and Yukon. Rates vary by province. You must also decide between the simplified method (using the prescribed rate) and the detailed method (tracking actual expenses like gas, insurance, maintenance). The choice affects your deduction and what records you need.

Manual vs. Automated Mileage Tracking

Most people start with a manual logbook - a physical notebook or a spreadsheet. It works if you are disciplined, but it is easy to forget entries or lose the book. CRA prefers a contemporaneous log, meaning you record each trip as it happens. Gaps or estimated entries raise red flags.

Automated tracking uses a mobile app or a feature built into your accounting software to record trips automatically. The app uses GPS to log start and end times, distance, and can classify trips as business or personal. The advantage is accuracy and consistency. Many Canadian accounting firms recommend automated tracking to clients for this reason.

For 2026, automated tracking is increasingly the standard. Even CRA expects digitized records. If you are a CPA firm handling multiple clients, you need a solution that centralizes mileage logs and integrates with your practice management workflow.

How CRA Views Mileage Logs

CRA's administrative policy on vehicle expenses is clear: a log must be maintained for the entire year, and it must show total business and personal kilometres, plus separate logs for each vehicle. The log should be kept in a durable format. If you are audited, CRA may ask for the log and supporting documents (e.g., gas receipts).

One common mistake is using a leap year without adjusting for 366 days. For 2026, note that it is not a leap year. For 2024, some accountants missed this. Another issue is mixing personal and business use incorrectly. If you drive 10,000 km in a year and 6,000 are business, your business use percentage is 60%. That percentage applies to actual expenses if you use the detailed method.

CRA also distinguishes between commuting (driving from home to a regular workplace) and business travel. Commuting is personal, not deductible. Only trips from the workplace to a client, or from home to a temporary work location, count. This distinction matters for many Canadian real estate agents and contractors who have a home office.

Step-by-Step Guide to Tracking Mileage in 2026

1. Decide your method: Simplified (prescribed rate) or detailed (actual expenses). Most small businesses use simplified because it is easier. But if your vehicle expenses are high, detailed may yield a larger deduction.

2. Set up a log: You can use a paper logbook, a spreadsheet, or an app. If you choose an app, ensure it exports to a format CRA accepts (PDF, CSV).

3. Record every business trip: For each trip, note the date, destination (address or city), purpose (e.g., client meeting, property inspection), and kilometres driven. If using an app, it does this automatically.

4. Track total kilometres: At year-end, note the odometer reading or the total app-tracked kilometres for the vehicle. Also track personal kilometres to calculate business use percentage.

5. Reconcile with expenses: If using detailed method, keep all gas, oil, insurance, maintenance, lease, and interest receipts. An app like Awditify can categorize these automatically.

6. Store logs safely: Keep logs for at least six years after the tax year, as CRA can reassess within that period.

If you are an accounting firm, you can help clients by offering a mileage tracking tool as part of your service. Many Canadian CPA firms centralize client work in one practice management platform and integrate mileage logs into the client portal. Awditify's features include receipt OCR and automated expense categorization that can handle vehicle expenses.

Real-World Scenario: A Small Business Owner in Ontario

Sara runs a home renovation business in Toronto. She uses her truck to visit job sites, buy materials, and meet clients. In 2025, she tracked mileage manually but missed several trips. At tax time, she guessed 12,000 km of business use. CRA audited and asked for her log. She had a sparse notebook. The auditor disallowed the deduction, and she owed $2,100 in tax plus interest.

For 2026, Sara switches to an automated mileage tracker built into her accounting software. She uses Awditify's mobile app, which records trips automatically and syncs with her books. At year-end, she exports a clean log that shows 14,350 business km with GPS verification. She claims the deduction confidently. If CRA asks, she can show the detailed log. Sara's bookkeeper also appreciates the centralized records.
