A person who performs work for an organization is an employee, unless he or she is in business for themselves. As an employee, he or she is generally entitled to all of the rights under the Employment Standards Act, 2000 (ESA) including minimum wage.
There are some exceptions, but they are very limited. Unpaid internships are illegal under Ontario law unless they fall within an exception.
One possible exception is a trainee. Trainees, however, will generally be considered to be employees for the purposes of the ESA and therefore must be paid, unless all of the conditions below are met:
The ESA does not prohibit an employer from hiring as an employee someone who was a former unpaid trainee who met all six of the conditions above.
Another exception concerns college and university programs. The ESA does not apply to an individual who performs work under a placement program approved by a university or college of applied arts and technology.
Finally, the ESA does not apply to true volunteers,such as a person helping out a neighbour or friend or volunteering at a charity. The legal test for a true volunteer arrangement looks at several factors, but merely agreeing to work without pay does not in itself make an individual a volunteer.
