Legal gender change has many different contexts within Canada. Birth certificate is arguably the most recognized authoritative statement of gender. Changes to this document are regulated province by province. Some require proof of surgery for a certificate change, others require a psychologist's statement. For citizens born outside of Canada, recognition is at the federal level in the form of changes to one's certificate of Canadian citizenship and/or passport which at present requires proof of surgery to obtain.

Some provinces allowed "X" as a gender identity on drivers licenses and birth certificates.

Federal human rights law applies directly to only federal government employment and employers which fall under federal jurisdiction. Gender identity is only implicitly protected under interpretation of the law by the Canadian Human Rights Tribunal. Attempts have been made to have gender identity and gender expression added as protected classes to both the Canadian Human Rights Act and Criminal Code, though none of these attempts so far has been successful.

Provincial human rights acts are separate, but Supreme Court precedent exists for requiring provinces to protect the same classes as the Canadian Human Rights Act. At this time all provinces protect against employment discrimination on the basis of sexual orientation. Of the provinces only Ontario has explicit protection on the basis of both gender identity and gender expression in its human rights code, though several provide implicit protections on the basis of gender identity or "transsexualism" under the category of "sex" or "gender".

“Gender identity and gender expression” were added by Bill 7, the Alberta Human Rights Amendment Act which received royal assent in 2015.
