An employer may require an employee to provide a medical note from a health practitioner such as a doctor, nurse practitioner or psychologist when the employee is taking the leave because of personal illness, injury, or medical emergency if it is "reasonable in the circumstances".
However, the employer can ask only for the following information:
- the duration or expected duration of the absence
- the date the employee was seen by a health care professional
- whether the patient was examined in person by the health care professional issuing the note
Employers cannot ask for information about the diagnosis or treatment of the employee's medical condition.
