Unity Park was designated as Richmond Hill's "Peace Park" as part of Canada's 125th Birthday in 1992.
"Peace Parks Across Canada" was conceived and organized by the International Institute for Peace through Tourism (IIPT) in collaboration with "CANADA 125" and the National Capital Commission. As Canada celebrated its 125th Birthday, some 400 cities and towns across Canada dedicated a Park to Peace – with most parks dedicated at Noon local time, October 8th, as the National Peacekeeping Monument was being unveiled in Ottawa. The members of the winning design team included Cornelia H. Oberlander, landscape architect. Supporters included the Federation of Canadian Mayors and Municipalities, Canada Parks and Recreation Association, the Tourism Industry Association of Canada, Heritage Canada, World Wildlife Fund Canada, Friends of the Earth, Canadian Society of Landscape Architects, and local Rotary Clubs all across Canada. Project sponsors included VIA Rail, Greyhound Lines Canada, Ltd., CP Hotels and Resorts, Ramada International Hotels and Resorts, Four Seasons Ltd., Meridien Hotels, Concept 3 Advertising and Programmed Communications, Ltd.
Peace Parks Across Canada" has served as the foundation in launching the "IIPT Global Peace Parks Program" on the 11th hour, of the 11th day, of the 11th month, 2000
At noon on October 9th, 2007 – one day after the precise 15th Anniversary of the original dedications, and as Canada continues to be a beacon of peace, Tolerance, and Understanding in a world of increasing violence and distrust, and a nation that celebrates diversity, a nation-wide re-dedication was co-ordinated.
Each of the original Peace Parks incorporated a ‘Bosco Sacro’ (Peace Grove) of 12 trees as a symbolic link with one another, and with nature - and as a symbol of hope for the future. The 12 trees were also symbolic of Canada’s 10 Provinces and two Territories. As there are now three Territories, a 13th tree was planted as part of the "Re-dedication Ceremony."
