You can deduct expenses for field trips for the children in your care. You should support these expenses with documents such as taxi receipts, parking receipts, and entry-ticket stubs.
If you use your vehicle occasionally to take children on field trips, you can claim the cost of gas used instead of calculating a percentage of your total vehicle expenses. For more information, see Motor vehicle expenses.
Report this expense on line 9200 of Form T2125, Statement of Business and Professional Activities.
