The Ontario Human Rights Commission (OHRC) interprets and sets guidelines on how to fulfil the Ontario Human Rights Code. 

On April 14, 2014, it released a new policy on the human rights of transgendered persons.  The policy, offering guidance for employers and service providers, can be found here: http://www.ohrc.on.ca/en/policy-preventing-discrimination-because-gender-identity-and-gender-expression.
