Each year, the Centre for Peace and Advancement brings together a diverse group of peace and social justice-oriented organizations from throughout Waterloo Region in honour of Peace Week. The Peace Week Community Calendar highlights a variety of virtual and in-person events happening between September 21st and September 30th, all of which celebrate, promote, or honour peacebuilding efforts in some way.
September 21st was deemed the International Day of Peace by the United Nations in 1981. Every year, peace week celebrations are inspired by a new theme. For 2026, this is "Invest in Peace — For Everyone, Everywhere, Every Day." Join your local and global communities to honour the "everyday architects of peace" working to make the world a more equitable, peaceful, sustainable place for people in the present and generations to come.
