Reservist Kirby Tott's military funeral held in Prince George, B.C.

More than 800 mourners gathered under grey skies in Prince George, B.C. on Wednesday for the funeral of Canadian soldier Kirby Tott. 

Tott, a 25-year-old prison guard and a reservist with the Rocky Mountain Rangers, died suddenly during training exercise at the Canadian Forces Base Shilo in Manitoba. He was learning to reinforce a trench when he collapsed suddenly.

An autopsy is underway to determine the cause of death.

On Wednesday, uniformed soldiers, prison guards, and veterans accompanied Tott's casket in a block-long parade through the streets of Prince George.

His family remembers Tott as a man with a kind heart, infectious smile, and a sarcastic sense of humour. 

Clara Archibald joined the Rocky Mountain Rangers at the same time as Tott and came to his funeral to say goodbye.

"He was a very funny person, very enjoyable to be around, and he really knew how to pick your spirit up if you were ever feeling down," she said.
