Ontario’s justice system is undergoing a significant reshuffle, with five new judges appointed to the Superior Court of Justice—each bringing decades of courtroom experience and regional expertise at a time when courts continue to manage post-pandemic pressures and rising case complexity.
Justice Minister and Attorney General Sean Fraser confirmed on March 27 the appointments of Scott G. Pratt, Cheryl C.M. Siran, Constance Nielsen, Stephanie J. Ouellette, and Sean D.R. Heeley. The judges will serve in Windsor, Kenora, Oshawa, London, and Hamilton respectively, filling vacancies created by retirements, resignations, and judicial transfers.
Leadership and continuity across Ontario courts
Scott G. Pratt will take his seat in Windsor, replacing Justice G.W. King, who became a supernumerary judge effective November 3, 2025. Pratt has served on the Ontario Court of Justice bench since 2019 and played a key leadership role as local administrative justice, helping guide the court through pandemic-related disruptions and implementing protocols to address case backlogs.
Before his judicial career, Pratt worked extensively as an assistant Crown attorney across Hamilton, Niagara, Brampton, and Windsor. His background also includes civil litigation in Toronto and criminal defence work in Hamilton. Called to the Ontario bar in 2000, he holds degrees in psychology and law from the University of Windsor and currently serves as West region director on the Association of Ontario Judges’ board.
In Kenora, Cheryl C.M. Siran replaces Justice J.S. Fregeau, who assumed supernumerary status on October 25, 2025. Siran’s appointment reflects deep regional roots, having spent her entire legal career in Kenora. She began as a Legal Aid Ontario summer student and articled with the Crown attorney’s office before joining Hook, Seller & Lundin LLP, where she eventually became a partner.
Her early practice focused on criminal and family law, later expanding into property, estate, and construction litigation, along with residential and cottage real estate transactions. Siran has held several leadership roles, including chair of the Federation of Ontario Law Associations and president of the Kenora District Law Association. She was appointed deputy judge of the Small Claims Court in 2018 and served as northwest regional bencher with the Law Society of Ontario, co-chairing its access to justice committee. She has also contributed to the Ontario judicial appointments advisory committee and represented the Ontario Deputy Judges Association.
Constance Nielsen will serve in Oshawa, filling a vacancy created after Justice M.P. Shelston resigned effective May 31, 2025. The position was relocated from Ottawa following the transfer of Justice K.D. Leef. Nielsen built her career in family law, initially working at a boutique firm before moving into sole practice.
She has served as a Children’s Lawyer agent, duty counsel, and dispute resolution officer—roles that support early and fair resolution of complex family matters. Nielsen was also part of Legal Aid Ontario’s Domestic Violence Panel. Beyond the courtroom, she contributed to the York Region Law Association board, co-chaired its family law committee, and supported mentorship and legal education initiatives.
In London, Stephanie J. Ouellette joins the Family Court, replacing Justice P.J. Henderson, who resigned on October 31, 2025. Ouellette began her career as an associate at Legate and Associates (now Legate Injury Lawyers) before establishing her own family law practice with a strong focus on child protection litigation.
Her work has involved appearing before the Superior Court of Justice on complex and sensitive cases involving children and families. She previously led the London chapter of the Ontario Association of Child Protection Lawyers and has served as a Legal Aid Ontario panel lawyer, reinforcing her long-standing commitment to access to justice in family law.
Sean D.R. Heeley will sit in Hamilton’s Family Court, replacing Justice D.A. Jarvis, who became a supernumerary judge effective March 1, 2025. The vacancy was based in Hamilton after Justice T.W.Y. Law was transferred to Newmarket.
Heeley’s legal career began as a student at a Hamilton-based firm where he later rose to counsel, partner, and ultimately sole owner. His practice spanned family law, real estate, wills and estates, civil litigation, and criminal law. He has appeared before the Ontario Court of Appeal and has been deeply involved in the legal community, serving as a trustee of the Hamilton Law Association and contributing to its family law, history, bench and bar, and rules committees, as well as a community resource liaison committee.
Why these appointments matter now
These appointments come at a crucial moment for Ontario’s courts, which continue to balance increased caseloads, evolving legal challenges, and the need for faster dispute resolution. By appointing judges with strong regional ties and diverse legal backgrounds—from criminal prosecution to family law and civil litigation—the system is positioning itself to deliver more efficient and locally informed justice.
Across Windsor, Kenora, Oshawa, London, and Hamilton, the arrival of these five judges is expected to strengthen court operations and improve access to justice—particularly in family and community-focused cases where demand remains high.
