It is discrimination if you fire, demote or lay off an employee because she is or may become pregnant or she is away on maternity leave or disability leave related to pregnancy. Employers have a duty to accommodate a pregnant woman unless it would cause undue hardship. This may include changing her job duties temporarily or providing time off work.
The Code does not specifically define the ground of “sex,” but the OHRC considers it to be related to a person’s biological sex, male or female. Men and women receive equal protection under this ground. The ground of “sex” also includes a broader notion of “gender,” which can be described as the social characteristics attributed to each sex.
The Code protects men and women from harassment and discrimination, including assumptions about their abilities that result from stereotypes about how men and women ”should” behave, dress or interact. The right to equal treatment without discrimination because of sex also applies to pregnancy.
