In January 2009, Mr. Hourigan was appointed a judge of the Ontario Superior Court of Justice. Assigned to the Central West Region, he presided over jury and non-jury trials and proceedings in civil, criminal, and family cases in the busiest court jurisdiction in Canada.

Mr. Hourigan continued his commitment to public service beyond his duties on the court. In 2021, he was appointed by the Ontario Minister of Transportation as the Commissioner of a Public Inquiry investigating the commercial and technical causes of derailments and breakdowns of the Ottawa Light Rail Transit system. The Inquiry included over one hundred witness interviews, publicly broadcast hearings, community meetings, and an expert panel. One year later, he released a detailed report to the Government of Ontario, which included 103 recommendations to address the issues with the Ottawa LRT and ensure they do not recur in other major infrastructure projects. He recently completed an investigation under the Police Act for the Minister of Public Safety and Emergency Services for Alberta regarding the interactions between the City of Edmonton, the Edmonton Police Service, and the Edmonton Police Commission. That investigation generated recommendations regarding civilian oversight of police services.
