Toronto-born Robert Roy Haw went to World War Two as a flight lieutenant with the Royal Canadian Air Force's 431 Squadron.
On March 11, 1945, the 26-year-old wrote home: "Dear Pop, think I better get around to reminding you that your youngest is still alive and kicking."
Four days later, Haw and his flying Lancaster X KB-815 SE-K crew went missing. In 1948, the wreckage of crew's aircraft was discovered in Perwez, Belgium. The men were buried in a communal grave.
Haw had been married for just 10 days when he left for war. His wife, Wilhelmina, died in the 1980s. His wartime letters were kept and preserved by one of his sister-in-laws.
The Toronto Star reports that the soldier's family was Googling his name one day and discovered a message board discussing Haw's particular plane and crew. The family discovered that a monument had been erected at the crash site. A dedication ceremony will take place this May.
Haw's sister-in-law's daughter, LeAnne Taylor, will fly to Belgium to honour Haw's memory.
"It's a family thing, I've always felt a sense of connection to him for some reason," she said.
