Jason Diceman - Public Consultation Professional

Jason Diceman is a professional meeting facilitator and public participation expert.

He leads the planning and implementation of large multi-stakeholder collaborative workshops that lead to clear outputs, and the design and management of affordable and productive community engagement processes.  

Since 2010, Jason has held the full time position of Senior Public Consultation Coordinator for the City of Toronto. He has lead public consultations for some of the City’s most controversial and high profile infrastructure studies, including downtown separated bike lane installations, the redesign of Front Street at Union Station, new roads and bridges in Liberty Village, contentious multi-use trails, and the Gardiner Expressway financing.

In 2004, Jason Diceman invented idea rating sheets (originally called “Dotmocracy Sheets”). These simple paper based tools make it easy to find agreements among large numbers of people, both within and outsude of meetings.  Idea rating sheets are now used by hundreds of meeting facilitators in over 33 different countries, in more than 15 different languages.

In 2016 Diceman is releasing a new invention: a non-electronic hardware tool for large group decision making, called Feedback Frames.


Jason has researched consensus cultures in eco-villages in Denmark and spent six months in Venezuela investigating their communal council local participatory democracy system.  He is a mentor through the International Association for Public Participation (IAP2) and is often invited to give workshops and present at conferences. A sample of some speaking engagements include:



  • Master of Arts, Design for Interaction, University of Westminster (UK), 2002
  • Bachelor of Arts, Radio and Television, Ryerson University, 2001


  • National Issues Forums Moderator, 2007
