This article examines the processes of youth engagement in an "invited space" for Canadian secondary school students. The organizers created a participatory citizenship education space in which Canadian students discussed their views and visions and developed their policy position on global citizenship and global citizenship education. The content and process of "The National Youth White Paper on Global Citizenship" (2015) demonstrated that youth have important policy knowledge and understand they live in a globalized world that includes unacceptable inequalities and oppressions. They also understand that, through acts of citizenship, these conditions can be changed. The article discusses how students were engaged in developing public opinion and working in the public sphere while developing the policy paper on the topic of global citizenship.
