A total of 40,000 veterans will be honoured, as well as the 158 soldiers, one diplomat, one journalist and several civil servants who were killed in the conflict.
Rick Hansen, the B.C. Paralympian whose Man in Motion world tour in the mid-1980s raised money for spinal cord research, and whose foundation still raises money for the cause, will emcee the event.
The breakfast will be sponsored by the organization True Patriot Love, which raises money to support soldiers, veterans and their families, and is receiving offers of financial support from the private sector.
However, the government will pick up any extra costs for the families' travel, meals and accommodations while in Ottawa.
The day will also feature a relay called Soldier On — runners will carry the last flag from Afghanistan from Trenton, Ont., to Ottawa.
The Afghanistan memorial consisting of 190 plaques within eight panels will be on display in the Hall of Honour on Parliament Hill.
The memorial, which does not yet have a permanent home, will go on tour across Canada after the ceremonies.
