The 34-year-old's mother hopes a big crowd comes out to cheer when he finally receives the medal he was awarded after original third-place finisher Andrei Mikhnevich was slapped with a lifetime ban for doping.
"In some ways, I guess his moment was stolen," Judy Armstrong told Daybreak Kamloops' Shelley Joyce.
Armstrong finished fourth in the shot put competition in Beijing, less than one centimetre behind Mikhnevich of Belarus.
But that didn't stop him from celebrating at the time.
"I was there in Beijing and Dylan was very happy because he threw over 21 metres. He had a Canadian record, so he was really happy, but I think after reflecting and just closing by a centimetre, it was a bit bittersweet," she said.
"He's not one to mull over a negative situation. He just moved on and it gave him more energy to move forward."
Armstrong said her son is now training for the 2016 Olympics in Rio de Janeiro.
"Moral of the story is in the end, honesty prevails," she said. "For those that try to cheat the system, they do eventually get caught."
Dylan Armstrong receives his medal for the 2008 Olympic Games on Sunday, Feb. 15 in Kamloops at the Tournament Capital Centre at 12:45 p.m.
