The employee is a shareholder of the employer - will CPTL still calculate an EI deduction?

Employees who are also shareholders or owners of an employer are not eligible for EI coverage, and as such should not have EI premiums deducted from payroll amounts. EI exemptions also exist for certain other types of employees and/or employment situations (see CRA website for details). To exempt an employee from EI, set the appropriate value in the EmployeeData.isEIexempt input parameter data field.
