CRA takes an expansive view of what constitutes regular places of employment so as to render reimbursements for related travel as taxable benefits

CRA considers that if an individual has multiple regular places of employment (RPE) and travels between them during the day, the trip from the individual’s home to the first RPE and the trip home from the last RPE is personal, whereas travel between RPEs is considered employment-related – so that reimbursement of or allowances respecting the former but not the latter would give rise to employment benefits. In this context, CRA stated that “travel between an employee’s home and their employer’s business location is personal, even when the employee has a home office that is a regular place of employment” (cf. Cork), and that “a location may not be a RPE for an individual if, for example, the individual works at that particular location only once during the year or perhaps for only a few days in the year.”
