Dozens of life-size silhouettes are being erected across Canada to commemorate 100 years since the end of the First World War and offer some perspective of how gruesome the fight had been.

As part of the 鈥淭here But Not There鈥� campaign, six-foot-tall silhouettes of soldiers are being installed in public spaces around Canada 鈥渢o better understand how the war came to affect millions of people from countries around the world,鈥� 

鈥淭hese are the ghosts of those who came before us,鈥� Gen. Rick Hillier, former Chief of Defence Staff with the Canadian Forces, told CTV鈥檚 Your Morning on Wednesday.

鈥淭hose ghosts line every path we take now as a nation and we can learn from that.鈥�

The program launched in the U.K. in February and has since brought in more than $4 million in donations. In Canada,the silhouettes have been placed at several landmarks, including outside Parliament Hill and the Tomb of the Unknown Soldier in Ottawa and at Nathan Phillips Square in downtown Toronto, to name a few.

Sales of the silhouettes, including a miniature 25-centimetre version, raise money for several international charities that support veterans. The benefitting charities include the True Patriot Love Foundation, which supports Canadian veterans, and the Invictus Games Foundation, which uses the power of sport to help rehabilitate ill and injured veterans.

Natacha Dupuis, the 2017 Invictus Games Team Canada co-captain, lives with post-traumatic stress disorder following a 2009 tour of duty in Afghanistan. She earned five gold medals at the most recent Invictus Games last fall in Toronto 鈥� a feat she said wouldn鈥檛 have been possible without extra help.

鈥淚 would certainly not be where I鈥檓 at today without the support of the different charities,鈥� Dupuis said.

The campaign has also gained the support of celebrity survivalist and British Army veteran Bear Grylls who said: 鈥淚t is through remembering and honouring the past that we can best stand alongside those facing so many scars of conflict today.鈥�
