When claiming meals for short haul trucker, can I claim a meal for every 4 hours away from home terminal up to the 51.00 per day?

As a short-haul truck driver - If you’re back home within 24 hours of your departure, your meal expense deduction is 50%. And CRA expects you to eat at least breakfast and perhaps supper at home.

What if I eat more than three meals a day?

The old “every four hours is a meal” rule doesn’t apply. If you’re away for 12 hours you qualify for three meals; for less than 12, zero meals.
