Employers are required to deduct and remit Canadian income taxes (as well as Canada Pension Plan and Employment Insurance premiums) from their employees. If they fail to do so they are subject to interest and penalties. If they hire workers as independent contractors the risk and liability is with the employer if the Canada Revenue Agency (the Canadian income tax department) determines that the worker is in fact an employee.
