On August 20, 1970, one of the deadliest tornadoes in Canadian history tore through Ontario's Nickle Belt.
The F3 tornado demolished houses and caused catastrophic damage to Sudbury and nearby communities.
Lively was the hardest hit with 300 homes damaged. A second tornado struck the field, where half of the community's 600 homes were damaged beyond repair.
There was little warning as Sudbury's airport didn't have radar able to detect tornadic activity.
Six people were killed.
