Do I have to include automobile expenses on the monthly statements?

Do I have to include automobile expenses on the monthly statements?

Regarding a sales person who gets kilometer reimbursements for a car.

I work as a sales representative for a company. I am paid a salary but don’t get a car allowance, but a kilometer reimbursement of my car expenses.

Since it is money that isn’t reflected in my T-4 slip, do I need to include this money in my monthly statements?
