Thunder Bay's Bombardier plant is celebrating it's 100th anniversary this week.
And as part of the festivities two commemorative plaques were unveiled there.
With one plaque, Parks Canada recognized the factory's World War II "Can Car" era.
When a workforce largely comprised of women--around 3,000-- produced more aircraft than any other plant in Canada.
And one woman in particular was honoured with the other plaque unveiled today.
Elsie MacGill worked as a senior engineer at the plant and had a huge hand in the plants wartime production effort.
Voyage North's Josh Lynn talks to historian Gordon Burkowski about MacGill's legacy.
