“Feeling passionate about the power of play ever since I climbed on board of a Playbus, back in 1998 in Hamburg, to work with refugee children. They had no common language but I witnessed how the power play brought them together in joy. Since then I have studied Playwork (University of Brighton, FDA), promoted and provided for Article 31, the Children’s Right to Play in social hotspots, schools for children with additional needs, run mobile summer community play programs and free play centred family days for children and their imprisoned fathers at HMP Lewes. After running Brighton and Hove City Council’s Playbus for a decade I joined in 2016 the play forces with Michael Follett & OPAL. If only both my boys could have enjoyed an OPAL school. I feel deeply grateful to make a difference to an ever-growing number of school children enjoying and benefiting from rich and diverse player offers on every school day! “

OPAL International

OPAL in Canada – Brenda Simon

OPAL was introduced into Canada was by Brenda Simon, a human rights lawyer and teacher, who began with PLAYbynature in 2011 to advocate for play provision in Ontario, Canada.    In 2013, Brenda travelled to Bristol to learn about OPAL U.K., becoming Canada’s first certified OPAL mentor. In 2014, Brenda contributed to the Position Statement on Outdoor Active Play,  which created a new public awareness of play deprivation in Canada.  With support from the Lawson Foundation and the Ontario Trillium Foundation, Brenda joined forces with Earth Day Canada to form a partnership with the Toronto District School Board.

OPAL grew, under Brenda’s leadership, from a small early years pilot at 6 schools to a $1.3 million programme, reaching almost 50 schools over 4 years and approx.16,000 school children from kindergarten to Grade 6. Three school boards eventually participated:  the Toronto District School Board, the Toronto Catholic District School Board and the York Region District School Board.  The project included a commissioned study and 3 professional learning days reaching over 600 educators. In 2020 Transform Lab completed a second study of the OPAL.

In 2019, the Dr Eric Jackman Institute of Child Study Laboratory School (JICS) at the University of Toronto became Canada’s first laboratory school to adopt OPAL.  Hundreds of educators visit the JICS Lab School each year from across the globe to learn more about its developmental focus, the research and inquiry-led teaching practices that make it a global leader in education.

Brenda has written Recommendations for a Play Policy that would bring play-work principles to all of the 451 elementary schools in the TDSB, Canada’s largest school board.

Brenda (Twitter: @BrendaRoseSimon) is currently the Program Director of Natural Curiosity (Twitter: @naturlcuriosity) at the JICS Lab School, Ontario Institute of Studies in Education, University of Toronto.
