The 0.4-hectare park was dedicated in 2005 to honour June Callwood, an internationally acclaimed community activist, journalist, author and television host. She died in 2007. The Park was designed by Toronto-based multi-disciplinary firm gh3 and was opened to the public in 2014 and was revitalized in 2022.
The opening and the revitalization were supported in part by the Garden Club of Toronto and its donors.
