The Honourable Jody Wilson-Raybould, Minister of Justice and Attorney General of Canada, today announced the following appointments under the new judicial application process announced on October 20, 2016. The new process emphasizes transparency, merit, and diversity, and will continue to ensure the appointment of jurists who meet the highest standards of excellence and integrity.

In 2014, she joined KPMG Law LLP as senior partner, a position she held until her appointment.

Justice Monaghan has been extensively involved in the tax community, serving as a member of the CBA-CPA Canada (Canadian Bar Association-Chartered Professional Accountants Canada) Joint Committee on Taxation for nearly ten years, including two years as its co-chair. She is an adjunct member of the faculty of Osgoode Hall Law School’s Professional LL.M. program.

Quick facts

  • In 2017, the Minister of Justice made 100 appointments and elevations – the most a Minister of Justice has made in one year in at least two decades. Of these appointees, half are women, four are Indigenous, and 16 have self-identified as a member of a visible minority population, LGBTQ2, or a person with a disability.

  • The Government of Canada is committed to promoting access to justice for all Canadians. To improve outcomes for Canadian families, Budget 2018 proposes $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.

  • In addition, Budget 2018 proposes funding for a further seven judicial positions in Saskatchewan and Ontario, at a cost of $17.1 million over five years.

  • The funding outlined in Budget 2018 comes on top of resources allocated under Budget 2017, which created 28 new judicial positions across the country.

  • Additionally, the Government will ensure that a robust process remains in place to allow Canadians to voice their concerns and submit complaints about judicial conduct to the Canadian Judicial Council and the Office of the Commissioner for Federal Judicial Affairs. This investment of $6 million over two years, beginning in 2018-2019, will support the judicial discipline process through which allegations of judicial misconduct are investigated.

  • 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. Sixteen Judicial Advisory Committees have been reconstituted to date.
