The CRA’s contact centres for its individual and business tax enquiries lines were open Monday to Friday from 8:00 a.m. to 8:00 p.m. and Saturday from 9:00 a.m. to 5:00 p.m., local time. However, the Office of the Taxpayers’ Ombudsperson (OTO) found that the CRA’s telephone system was preventing callers from reaching an agent if the contact centre was not open in the time zone associated with the caller’s phone number.
