Quick facts

  • At the Superior Court level, more than 560 judges have been appointed since November 2015. These exceptional jurists represent the diversity that strengthens Canada. Of these judges, more than half are women, and appointments reflect an increased representation of visible minorities, Indigenous, 2SLGBTQI+, and those who self-identify as having a disability.

  • The Government of Canada is committed to promoting access to justice for all Canadians. To improve outcomes for Canadian families, Budget 2018 provides funding of $77.2 million over four years to support the expansion of unified family courts, beginning in 2019-2020. This investment in the family justice system will create 39 new judicial positions in Alberta, Ontario, Nova Scotia, and Newfoundland and Labrador.

  • Federal judicial appointments are made by the Governor General, acting on the advice of the federal Cabinet and recommendations from the Minister of Justice.

  • The Judicial Advisory Committees across Canada play a key role in evaluating judicial applications. There are 17 Judicial Advisory Committees, with each province and territory represented.

  • Significant reforms to the role and structure of the Judicial Advisory Committees, aimed at enhancing the independence and transparency of the process, were announced on October 20, 2016.

  • The Government of Canada is committed to promoting a justice system in which sexual assault matters are decided fairly, without the influence of myths and stereotypes, and in which survivors are treated with dignity and compassion. Changes to the Judges Act and Criminal Code that came into force on May 6, 2021, mean that in order to be eligible for appointment to a provincial superior court, candidates must agree to participate in continuing education on matters related to sexual assault law and social context, which includes systemic racism and systemic discrimination. The new legislation enhances the transparency of decisions by amending the Criminal Code to require that judges provide written reasons, or enter them into the record, when deciding sexual assault matters.
