Due to changes in how "age" is defined in Ontario's Human Rights Code:

	none of the other answers are correct
	most employers can now only insist that an employee retire once that employee reaches 70
	most employers cannot insist that an employee retire at age 65 but an employee who is dismissed after that age cannot sue for wrongful dismissal damages
	most employers cannot insist than an employee retire just because he or she has reached the age of 65
