The Ottawa Association of Chinese–Canadian University Alumni (OACCUA) is an independent, non-political and not-for-profit volunteer community organization, founded in 1999 in Ottawa. Its objectives are to promote communication and to foster community spirit, through organizing educational, professional, and cultural activities.

OACCUA has initiated and organized, for a number of years, the traditional Chinese New Year Celebration at Parliament Hill. OACCUA also organizes annually summer beach volleyball tournament and the Go tournament, and co-organizes Table Tennis tournament bi-annually. OACCUA has just launched an annual 1000 Chinese-character spelling bee contest, the first to be held in May 2015, to encourage the preservation of Chinese language in children.

In 2005, OACCUA launched its first By Youth For Youth (BYFY) benefit concert to raise funds for the victims of the 2004 tsunami in South Asia. Since then, BYFY has become OACCUA's trademark event, with four concerts organized so far, raising over $20,000 in total for children worldwide. On January 11, 2015, OACCUA hosted the 4th By Youth For Youth concert, and celebrated the 15 year anniversary with great success.

Ottawa Go School focuses on teaching the Go game for kids. It is currently the only Go school in Ottawa. The school offers all levels of Go lessons at four locations in the Ottawa area with the goal to promote Go in Canada, let more children know what is Go, learn to play the Go and enjoy the happiness of playing Go.
