Final answer:
An overtime meal allowance is non-taxable by the CRA if it is reasonable, given when an employee works overtime occasionally and must work longer than usual hours.
Step-by-step explanation:
The student's question is about when an overtime meal allowance is seen as non-taxable according to the Canada Revenue Agency (CRA). Under certain conditions, an overtime meal allowance or the cost of a provided meal is considered a non-taxable benefit if it is reasonable (generally $17 or less), the employee works overtime occasionally, and is required to work longer than their standard working hours. If the employer provides a meal or meal allowance under these conditions, the CRA does not tax this benefit. However, if these conditions are not met, the allowance may be taxable.
