Prime Minister Stephen Harper is designating May 9 as a national day of honour to commemorate Canada's mission in Afghanistan as he welcomes the last group of soldiers returning home in Ottawa Tuesday morning.

"Thank you to all members of the Canadian Armed Forces, to those who served in Afghanistan and those who made it possible for them to serve," Harper said.

The troops, escorted by CF-18 fighter jets, arrived at the Ottawa airport where they were greeted with a welcome ceremony that includes Governor General David Johnston, Defence Minister Rob Nicholson and Defence Chief General Thomas Lawson. 

Perhaps most importantly, the 93 soldiers were welcomed home by their families. The scene at the airport was one of warm embraces, smiles and tears.

The ceremony marks the formal conclusion of Canada's 12-year mission in Afghanistan. Canada lost 158 military members during the mission.
